# Tidebreak > Tidebreak is a local-first desktop agent with two modes. In work mode you point it at a folder, pick a model, and get back a spreadsheet, deck, memo, or working app, versioned on your own machine. In code mode you point it at a repository and it drives Claude Code, Codex CLI, opencode, or Grok CLI in isolated git worktrees, with per-turn diffs and pull requests you merge from the app. The software is free and Apache-2.0, built in Rust by Brightwave. Facts an agent can rely on: - Tidebreak is a desktop app. Packaged builds ship for macOS (signed, notarized Universal and Apple Silicon disk images), Windows (x86_64 and ARM64 installers), and Linux (AppImage and Debian package, x86_64 and ARM64). Release builds check for updates on every platform. - There is no Tidebreak account and no hosted inference. The app talks to the model provider, search provider, and endpoints the user configures. No Tidebreak server sits in the path. - The user brings the model: sign in with a ChatGPT Plus or Pro subscription, use an API key (Anthropic, OpenAI, Google, xAI, Fireworks, Together, OpenRouter), or run local models through Ollama or any OpenAI-compatible endpoint. Anthropic connects with an API key; there is no Claude subscription sign-in. - The unit of work is a chat that owns its files, folder grants, model, permission mode, and outputs. Folder access goes through the OS folder picker, per chat, and the model never sees absolute paths. - Code runs in a sandbox: the native macOS sandbox by default on macOS, or Docker, E2B, or Daytona. On Windows and Linux, no exec backend is selected until you configure one. Per-chat network policy applies on every backend. - Anything the agent saves becomes a versioned file. History is append-only; restoring an old version creates a new one. Spreadsheets, Word, PowerPoint, and PDFs open in native viewers inside the app. Built-in skills cover those formats. - Permission modes are per chat: Plan, Ask, Auto, and Allow all. Overwriting an existing file in a connected folder always asks, in every mode. - Connections beyond files: web search (the model provider's built-in search on Anthropic and OpenAI, or Exa, Tavily, Brave, Firecrawl, or self-hosted SearXNG), MCP servers over stdio or HTTP behind the chat approval gate (every MCP tool counts as sensitive), and REST APIs registered from an OpenAPI document with an explicit operation allowlist. There is no managed OAuth connector catalog, and there will not be one. - Code mode drives Claude Code, Codex CLI, opencode, and Grok CLI in isolated git worktrees on macOS, Windows, and Linux. Tidebreak downloads the pinned engine on first use and uses the engine's own sign-in. Grok CLI offers only Auto and Allow all, because it has no approval channel. - Code mode reviews what those agents produce: per-turn diffs, the same permission modes as work mode, pull requests with their checks and review comments, stacked pull requests as lanes, and a merge (squash, merge, or rebase) that only a user can start. No agent tool can merge. - Code mode repairs pull requests: hand the agent failing job logs, review feedback, or conflicts. Watch and fix survives app restarts and stops when the PR is ready. Durable triggers react to failed checks, conflicts, requested changes, a stale branch, ready-to-merge state, a merge, or a close, once per head commit. - Code mode runs several conversations per workspace in tabs, forks any finished turn, shows engine subagents as child rows, queues follow-ups, and steers a live turn. Turns on a shared worktree run in sequence. Several terminals per workspace open as tabs or split panes. - A Pull requests page tracks pull requests, workflow runs, and deployments across repositories. Analytics shows turn outcomes, tokens, prompt-cache traffic, estimated cost, and subscription usage. - On macOS, an in-app browser with its own profile is available in both modes. In code mode Claude Code, Codex CLI, and opencode receive scoped browser tools over MCP. Agent control of the browser is not available on Windows or Linux yet. - Work mode delegates background jobs to sandboxed agents, one level deep, up to four at a time. They check in for direction, survive a restart, and stop when the app closes. Queue follow-ups or steer the live turn in both modes. - Projects group chats and code workspaces with their own files. One inbox lists everything waiting on you across both modes. Voice input runs on a local whisper.cpp model or OpenAI and Gemini transcription. - A headless CLI exposes the same runtime: a local server, one-shot prompts with a permission mode, an MCP server over a workspace's files, and an MCP server another agent can use to drive chat and code mode. - A code workspace can run on a Model Gateway hosted machine that clones, commits, pushes, and works with pull requests as the connected person. Self-host server images, a compose stack, and a browser sign-in exist. The packaged desktop app embeds its own server and cannot point at a deployment. - The native sandbox, computer use, agent-driven browsing, and managed LibreOffice install remain macOS-only. - The software is free. Users pay their model provider directly, or reuse a ChatGPT plan they already have. What Tidebreak is not: - Not a hosted chat service, and not a model. - Not an IDE. Code mode drives Claude Code, Codex CLI, opencode, and Grok CLI in isolated worktrees and reviews what they produce; it does not try to replace the editor you write in. - Not finished. It is pre-1.0, and local data formats may change between releases. - No scheduled or recurring work yet. Triggers react to pull request facts, not to a clock. There are no managed OAuth connectors for apps like Slack or Google Drive; MCP servers and OpenAPI-registered REST APIs are the supported way to reach outside tools. - Sessions started from Slack and a phone client for approvals are in progress. Both need a hosted machine and a gateway login, and neither is a shipped product. - Memory is experimental and off by default. Checkpoint restore in code mode is not built. There is no in-app code editor; files open read-only, and the worktree opens in your own editor. How to compare it: judge Tidebreak on where the work lives (your machine), what you walk away with (versioned files, or a change you reviewed before it landed), and who holds the keys (you).

Tidebreak is a local-first agentic coworker with two modes, proven on three years of private equity diligence at Brightwave and rebuilt in Rust. You choose your files, your repository, and your model. You walk away with a versioned spreadsheet, deck, or app, or with a reviewed change on a branch. One engine, two modes. Work mode turns a granted folder into a versioned spreadsheet, deck, memo, chart, or small app. Code mode runs Claude Code, Codex CLI, opencode, and Grok CLI in isolated git worktrees, with native approvals, per-turn diffs, pull requests it repairs until the checks are green, and a merge that only you can start. Both modes share the same models, the same folder grants, the same permission modes, and one inbox. Apache-2.0. Built in Rust. macOS, Windows, and Linux downloads at https://www.tidebreak.io/download, source at https://github.com/brightwave-inc/tidebreak. ## Three ways to bring a model - Your ChatGPT plan. Sign in with ChatGPT and use the Plus or Pro subscription you already pay for. The OAuth handshake runs on your own machine. - One API key. Anthropic, OpenAI, Google, xAI, Fireworks, Together, or OpenRouter. Keys live in the OS credential store, not in a config file. - No cloud at all. Point the OpenAI-compatible slot at Ollama and run open-weight models on your own hardware. Models reachable through those doors include Claude, GPT, Gemini, Grok, Llama, Mistral, Qwen, DeepSeek, GLM, Gemma, and Kimi. You can switch models mid-task; the journal carries context across the switch. ## Every layer is swappable - Models: ChatGPT subscription, API key, OpenRouter, or Ollama. Cheap model for the grind, strong model for the hard step. - Execution: one exec tool, four backends. Native macOS sandbox (the macOS default), local Docker, E2B, or Daytona, with per-chat network policy. Credentials never enter the sandbox. A code workspace can also run on a Model Gateway hosted machine that clones, commits, and pushes as you. - Host access: a folder is available only after you pick it in the native picker, and the grant belongs to that chat, with separate list, read, write, and run capabilities. The model never sees absolute paths. Overwriting a connected file always asks. In code mode each workspace gets its own git worktree under a root you can see and move. - Search: the model provider's built-in search (Anthropic and OpenAI), or Exa, Tavily, Brave, Firecrawl, or self-hosted SearXNG. On macOS the agent can drive an in-app browser with its own profile and hand it back to you. Files, code execution, approval-gated MCP servers, and REST APIs registered from an OpenAPI document are the interface to your data; a managed OAuth catalog is deliberately not. - Work products: versioned files with in-app preview for spreadsheets, Word, PowerPoint, PDFs, and interactive charts, plus small local apps kept in an Apps library. Built-in skills for those formats. Append-only restore, so a wrong file is a recoverable event. Markdown and text outputs are editable in place, and every edit is a new version. - Trust: permission modes per chat (Plan, Ask, Auto, Allow all), keys in the OS credential store, state in SQLite on disk. Every MCP tool asks. An agent can open, repair, and update a pull request, but only you can merge it. ## What working in it looks like - Every deliverable keeps its history. Preview any version; restore one without deleting what came after. - Switch models mid-task. One task, one journal, any provider. - Folders are scoped to a chat. Access starts when you grant it and ends there. - Sensitive actions ask first, in every permission mode. - Every turn in code mode arrives as a diff. Read what the agent changed before any of it reaches your branch. - Agents never share a checkout. Each workspace works in its own git worktree, so parallel work never collides. - Hand it the pull request and walk away. Watch and fix survives a restart, repairs each new failure, and stops when the PR is ready for you. - Rules that fire on the pull request, not on a clock. Triggers react to failed checks, conflicts, requested changes, a stale branch, or ready-to-merge state, once per commit. ## Code mode - Four engines: Claude Code, Codex CLI, opencode, and Grok CLI. Tidebreak downloads the pinned engine the first time you pick it and uses the engine's own sign-in. - Several conversations per workspace, each in its own tab, and workspaces side by side. Fork any finished turn. Engine subagents show up as child rows. Turns on a shared worktree run in sequence. - Set the model, reasoning effort, and fast mode from the composer. Queue follow-ups or steer a live turn. - Pull requests without leaving the app: open or update, move a draft to ready, read checks and review comments, update a stale branch, resolve conflicts, and merge by squash, merge, or rebase. Stacked pull requests render as lanes. - One page tracks pull requests, workflow runs, and deployments across repositories. Analytics shows turn outcomes, tokens, prompt-cache traffic, estimated cost, and subscription usage. - Several terminals per workspace, as tabs or split panes, in the worktree. Open the worktree in your own editor whenever you want to type. - On macOS, Claude Code, Codex CLI, and opencode get scoped tools for an in-app browser with its own profile: snapshots, clicks, forms, waits, responsive viewports. ## Who builds it Brightwave. For three years we built enterprise research agents for private equity diligence, the kind of file someone stakes their career on. Tidebreak is that engine, rewritten in Rust and open-sourced. Around it we are building governed model and app gateways, policy-bound access to production infrastructure, and a fully supported coding workflow. See the roadmap at https://www.tidebreak.io/roadmap. ## Practical notes - Packaged builds ship for macOS (Universal and Apple Silicon), Windows (x86_64 and ARM64 installers), and Linux (AppImage and Debian package, x86_64 and ARM64).

Tidebreak is a local coworker with two modes: one that turns a folder into a spreadsheet, a deck, or a memo, and one that drives coding agents across a repository. It is not a hosted chat tab, and it is not an IDE, so no single product maps onto it exactly. These pages compare it to the tools people usually weigh it against, and they say plainly when the other tool is the better choice. ## [Tidebreak vs Claude](https://www.tidebreak.io/compare/claude.md) Claude is a family of models and the cloud products built on them. Tidebreak is an open-source desktop app with no model of its own, and one of the models you can run inside it is Claude, through an Anthropic API key. The closest product comparison is Claude Cowork. The real differences are model choice, where the work executes, and who controls the account, the quota, and the data. ## [Tidebreak vs ChatGPT and Codex](https://www.tidebreak.io/compare/chatgpt.md) This is not a rivalry. The easiest way to set up Tidebreak is to sign in with the ChatGPT Plus or Pro plan you already pay for. The question is where the work should happen. ChatGPT does its file work in OpenAI's cloud, with agent usage metered against your plan. Tidebreak is a workspace on your own machine that keeps every version of every file it produces, whichever model is behind it. ## [Tidebreak vs OpenWork](https://www.tidebreak.io/compare/openwork.md) OpenWork and Tidebreak agree on most of the premise: an open desktop agent for macOS, Windows, and Linux; your choice of model; local workspaces; skills; and MCP. They organize that work differently. OpenWork packages capabilities so that people and teams can reuse skills, plugins, and connections across the desktop app and other agents. Tidebreak centers the finished work: versioned documents with native viewers, sandboxed execution, and coding agents in isolated git worktrees with per-turn review. ## [Tidebreak vs OpenWorker](https://www.tidebreak.io/compare/openworker.md) OpenWorker is the closest philosophical sibling Tidebreak has: local-first, open source, bring your own model or run one through Ollama, and judged on finished work rather than chat. The practical difference is the center of gravity. OpenWorker leans into connected apps, inbox and calendar work, and scheduled sessions. Tidebreak leans into documents: sandboxed code execution and versioned spreadsheets, decks, and memos on your disk. --- Canonical: https://www.tidebreak.io/compare Site briefing for agents and crawlers: https://www.tidebreak.io/llms.txt --- # Tidebreak vs Claude Claude is a family of models and the cloud products built on them. Tidebreak is an open-source desktop app with no model of its own, and one of the models you can run inside it is Claude, through an Anthropic API key. The closest product comparison is Claude Cowork. The real differences are model choice, where the work executes, and who controls the account, the quota, and the data. ## One subscription, three surfaces "Claude" covers three products that share an account and a usage pool. claude.ai is the chat assistant, on web, desktop, and mobile. Claude Cowork, launched in January 2026, is the agentic product: you connect a folder, describe a goal, and it plans the steps and writes real files. Claude Code is the coding agent that defined the category, in the terminal, the IDE, and the browser. All three run Anthropic models exclusively, and all three draw down the same five-hour rolling limit and weekly cap on your plan. Agentic work drains that pool much faster than chat, and the limit regime has changed several times with little notice. That history is the most consistent complaint Claude users have, and it is worth knowing before you build a workflow on any of the three. ## Cowork is the closest match Cowork deserves a fair description, because it is good. On desktop it reads and writes files in folders you connect, spawns parallel sub-agents, and produces spreadsheets with working formulas, decks, and formatted documents. Anthropic put real engineering into isolation: code and shell commands run inside a dedicated local virtual machine, and cloud sessions run in per-session sandboxes on Anthropic's servers, which means a task can keep running after you close the laptop and you can watch it from your phone. Tidebreak works on the same shape of problem with different commitments. **Models.** Claude products run Claude. Tidebreak has no model of its own: you connect Anthropic, OpenAI, Google, xAI, Fireworks, Together, or OpenRouter with an API key, sign in with a ChatGPT Plus or Pro subscription, or run open-weight models locally through Ollama. You can switch providers in the middle of a task and the journal carries the context across. One honest detail: Tidebreak has no Claude subscription sign-in. Anthropic connects with an API key only. **Where the work runs.** Cowork's agent loop runs on your machine in desktop sessions, but its execution lives in a managed VM, its inference is always Anthropic's cloud, and its cloud sessions move the whole task server-side. Tidebreak's engine runs on your machine, state sits in SQLite on disk, and generated code executes in the native macOS sandbox by default, or in Docker, E2B, or Daytona if you point it there. Inference still goes to whichever provider you configured; with Ollama, even that stays on your hardware. **The account and the data.** Cowork requires a paid Claude plan. On consumer plans, Anthropic uses your sessions for model training unless you opt out, with a five-year retention default when you do not. Tidebreak has no account and no server of its own in the path. Your prompts and documents go to the provider you chose, under the terms of your own key or plan, and to nowhere else. **Deliverables.** Cowork writes files into your connected folder. Tidebreak treats outputs as a catalog: every file the agent produces is versioned, restore is append-only, and spreadsheets, decks, documents, and PDFs open in native viewers inside the app. When a run goes wrong, the previous version is still there. ## Tidebreak runs Claude Code Claude Code is the reference point for coding agents, and its ecosystem of extensions and hooks is deep. Tidebreak does not compete with it; code mode drives it, alongside Codex CLI, opencode, and Grok CLI, each in an isolated git worktree. You review every turn as a diff, open a pull request, hand it to watch and fix until the checks are green, and merge without leaving the app. What you gain over running the CLI directly is parallelism and review: several agents on the same repository at once, none of them writing over each other, and nothing reaching your branch until you have read it. What you give up is the terminal you already know. If you want one agent in one checkout and nothing between you and it, use Claude Code on its own. One honest detail: in code mode Claude Code uses its own sign-in, so a Claude subscription drives that engine even though Tidebreak's work mode connects to Anthropic by API key only. ## At a glance | | Tidebreak | Claude Cowork | | --- | --- | --- | | Made by | Brightwave | Anthropic | | License | Apache-2.0, source on GitHub | Proprietary | | Price | Free; you pay your model provider | Paid Claude plans, from $20/mo | | Models | Anthropic, OpenAI, Google, xAI, Fireworks, Together, OpenRouter, local via Ollama | Claude only | | Account | None | Claude account required | | Agent runs | On your machine | Desktop sessions local, cloud sessions on Anthropic servers | | Code executes | Native macOS sandbox, Docker, E2B, or Daytona | Managed local VM or cloud sandbox | | Output history | Versioned, append-only restore | Files written into your folder | | Platforms | macOS, Windows, Linux | macOS, Windows, web and mobile in beta | ## Choose Claude when - Work should continue with the laptop shut. Cowork's cloud sessions, scheduled tasks, and mobile monitoring have no Tidebreak equivalent; background agents stop when you quit the app. - You want a supported phone surface today. - Your inputs live in Microsoft 365, Google Drive, or Slack. Cowork ships managed connectors for them; Tidebreak's equivalent is MCP servers you configure yourself. - You want a finished product from a frontier lab, with team administration, compliance tooling, and enterprise support behind it. - You want one agent in one checkout, in the terminal, with no app around it. Code mode drives Claude Code, but it adds a workspace you may not want. ## Choose Tidebreak when - You want to pick the model per task, mix providers inside one piece of work, or keep inference on your own hardware with Ollama. - You do not want another account or subscription. An existing ChatGPT plan or any API key is enough to start. - You want the application itself to be open. Tidebreak is Apache-2.0 and the whole client is auditable. - Your deliverables need a history you can defend: versioned outputs, append-only restore, and native viewers for the files you actually hand to people. - You want the data and quota relationship to be between you and your model provider, with no second company metering it. ## Where Tidebreak is behind Tidebreak is pre-1.0. Local data formats can still change between releases, the native sandbox and computer use are macOS-only, and there is no scheduled work and no mobile app. If any of those matter to you this month, Cowork is the more finished product, and this page will still be here when you want to reassess. --- Canonical: https://www.tidebreak.io/compare/claude Updated: 2026-09-07 Site briefing for agents and crawlers: https://www.tidebreak.io/llms.txt --- # Tidebreak vs ChatGPT and Codex This is not a rivalry. The easiest way to set up Tidebreak is to sign in with the ChatGPT Plus or Pro plan you already pay for. The question is where the work should happen. ChatGPT does its file work in OpenAI's cloud, with agent usage metered against your plan. Tidebreak is a workspace on your own machine that keeps every version of every file it produces, whichever model is behind it. ## Same models, two places to work OpenAI's models are genuinely good at document work, which is exactly why Tidebreak supports them two ways: sign in with a ChatGPT Plus or Pro subscription, or use an OpenAI API key. Nothing on this page argues the models are the problem. The comparison is about the workspace around them. On OpenAI's side that workspace has consolidated. Since July 2026 one desktop app holds ChatGPT chat, ChatGPT Work, and Codex. Work is the agent: it plans multi-hour tasks, pulls context from more than a thousand connectors, produces sheets, slides, documents, and hosted web apps, and can run on a schedule. Codex is the coding agent, with a local CLI and cloud tasks that clone a GitHub repository and hand back pull requests. The reach is real and worth conceding plainly. ChatGPT has the largest user base in the category, memory that follows you across devices, phone apps, native editing inside Google Docs and Sheets, and a free tier. For a quick analysis of a file you are happy to upload, ChatGPT is the shortest path, and no download competes with a tab you already have open. ## Where the friction is The complaints that push people toward a local tool are specific and well documented. Files generated in ChatGPT live in a temporary sandbox. Step away too long and the spreadsheet you asked for is gone; download links in old conversations die with a "file expired" error. The finished file is a byproduct of the session rather than the point of it. On Free, Go, Plus, and Pro plans, conversations train OpenAI's models unless you find the toggle and turn it off, and the opt-out is not retroactive. Ads now appear on the Free and Go tiers. Agent usage is metered against plan credits with no published per-task pricing. And the platform moves under you: agent mode was removed in August 2026 without notice, and many users found out because their scheduled tasks silently stopped producing output. The Atlas browser lasted nine months. None of this means the products are bad. It means workflows built on them are rented. ## What Tidebreak changes Tidebreak moves the workspace to your machine and leaves the model relationship exactly where it was. Work happens in chats that own their folder grants, permission mode, and outputs. Files come from your disk through a folder picker rather than an upload box, and the results land back on your disk as versioned files that do not expire. Spreadsheets, decks, documents, and PDFs open in native viewers inside the app, and restoring an old version never deletes a newer one. Generated code runs in a sandbox, the native macOS one by default on a Mac, or Docker, E2B, or Daytona, with a per-chat network policy. There is no Tidebreak account and no metering of its own. Through the ChatGPT sign-in you spend the plan usage you were already paying for; through an API key you pay OpenAI directly. And because Tidebreak is provider-neutral, the same chat can move to Claude, Gemini, or a local model through Ollama when a task calls for it. ## Tidebreak runs Codex Codex is developer-shaped: a terminal, repositories, diffs, and an AGENTS.md file. People do bend it toward spreadsheets and reports, but document work in Codex is a workaround rather than the product. Tidebreak has both shapes. Work mode is that same instinct pointed at documents. Code mode drives Codex CLI itself, alongside Claude Code, opencode, and Grok CLI, each in its own git worktree, with per-turn diffs, a watch-and-fix loop that repairs the pull request until its checks are green, and a merge you make from the app. If you want Codex on its own in a terminal, use it directly. If you want several agents on one repository at once and a review step before anything lands, that is what code mode is for. ## At a glance | | Tidebreak | ChatGPT Work | | --- | --- | --- | | Made by | Brightwave | OpenAI | | License | Apache-2.0, source on GitHub | Proprietary | | Price | Free; runs on your ChatGPT plan or API key | ChatGPT plans; agent use metered | | Models | OpenAI, Anthropic, Google, xAI, Fireworks, Together, OpenRouter, local via Ollama | OpenAI only | | Account | None | OpenAI account required | | Agent runs | On your machine | OpenAI's cloud, with permission-gated desktop access | | Generated files | Versioned on your disk, never expire | Sandbox files expire; exports to connected apps | | Training on your data | None by Tidebreak; your provider's terms apply | On by default for Free, Go, Plus, and Pro | | Platforms | macOS, Windows, Linux | Web, mobile, macOS, Windows, Linux preview | ## Choose ChatGPT when - You want the agent in your pocket and your browser, on every device, with nothing to install or configure. - The task lives in connected apps: Slack, Gmail, Drive, Salesforce. Tidebreak can reach tools over MCP, but it has no managed connector catalog. - You need scheduled runs, or a free tier to start from. - You want Codex on its own in a terminal, without a workspace around it. ## Choose Tidebreak when - The output is the point. You need the file to exist tomorrow, with its history, on your own disk. - The inputs are local folders you would rather grant than upload. - You want OpenAI models today without being limited to them tomorrow, including models that never leave your hardware. - You want the tool itself open source and the only usage relationship to be the one you already have with your provider. ## Where Tidebreak is behind Tidebreak is pre-1.0. It has no mobile app, no managed connectors, and no scheduled tasks. The native sandbox and computer use are macOS-only. It is a young tool with a narrow, deliberate center: real files, produced locally, with a history. If your work is shaped like that, the trade is worth it. --- Canonical: https://www.tidebreak.io/compare/chatgpt Updated: 2026-09-07 Site briefing for agents and crawlers: https://www.tidebreak.io/llms.txt --- # Tidebreak vs OpenWork OpenWork and Tidebreak agree on most of the premise: an open desktop agent for macOS, Windows, and Linux; your choice of model; local workspaces; skills; and MCP.

Tidebreak centers the finished work: versioned documents with native viewers, sandboxed execution, and coding agents in isolated git worktrees with per-turn review. ## What OpenWork is OpenWork, from Different AI and OpenWork Labs, is an open desktop agent built on OpenCode primitives. Its local app is free and does not require an OpenWork Cloud account. You can sign in with a ChatGPT Plus or Pro plan, bring provider keys, add a custom OpenAI-compatible endpoint, or run a local model through Ollama. Packaged builds ship for macOS, Windows, and Linux. The desktop app works with local files and repositories. It supports skills, plugins, custom MCP servers, connected services, generated-file previews, and a built-in browser that the agent can drive. The product's distinctive idea is that this setup should travel: OpenWork's MCP gateway can expose assigned skills, plugins, and connections to Codex, Claude Code, Cursor, OpenCode, and other MCP clients. OpenWork Cloud adds the team layer. Organizations can publish capabilities, manage model providers and service connections, apply desktop policies, assign access by member or team, and run hosted workspaces. None of that is required for the local app. ## Where the two projects part ways **Portable capabilities versus finished work.** OpenWork treats skills, plugins, and connections as the units that should move between agents and teammates. Tidebreak supports skills and MCP servers too, but its primary unit is the result: a spreadsheet, deck, document, PDF, local app, or reviewed diff with its history attached. **Team control versus a personal workspace.** OpenWork already has an organization control plane with roles, shared connections, managed providers, policies, and optional hosted workspaces. Tidebreak has no account and no server of its own. Organization-managed models and connected apps remain on its roadmap. **Documents and code.** OpenWork can preview, edit, download, and reopen generated files. Tidebreak goes deeper on the handoff: every output is versioned, restore is append-only, and spreadsheets, Word documents, PowerPoint decks, and PDFs open in native viewers inside the app. Code mode drives Claude Code, Codex CLI, OpenCode, and Grok CLI in isolated git worktrees, shows every turn as a diff, watches the pull request until its checks are green, and leaves the merge to you. **Execution and automation.** Tidebreak's work-mode code runs in the native macOS sandbox, Docker, E2B, or Daytona, with a per-chat network policy. OpenWork lists isolated Docker or microsandbox workspaces as partially available. OpenWork has built-in browser control today and partial scheduled tasks. Tidebreak has an in-app browser on macOS in both modes, with agent control still partial and macOS-only, and no scheduled work. Its triggers react to pull request facts, not to a clock. **The license.** Tidebreak uses Apache-2.0 across its repository. Most of OpenWork uses MIT, while its enterprise directory uses the Fair Source License. ## At a glance | | Tidebreak | OpenWork | | --- | --- | --- | | Made by | Brightwave | Different AI / OpenWork Labs | | License | Apache-2.0 throughout | MIT core; Fair Source enterprise directory | | Price | Free; you pay your model provider | Free local app; paid team and enterprise services | | Account | None | None for local use; required for Cloud features | | Models | API keys, ChatGPT plan sign-in, or local via Ollama | ChatGPT plan sign-in, provider keys, custom endpoints, or local via Ollama | | Primary unit | Versioned files and reviewed diffs | Shareable skills, plugins, and connections | | Team administration | On the roadmap | Available through OpenWork Cloud | | Generated files | Versioned with native Office and PDF viewers | Preview, edit, download, and reopen | | Coding workflow | Four coding agents, isolated worktrees, per-turn diffs, pull requests, watch and fix | OpenCode-based workspace agent | | Sandboxed execution | macOS sandbox, Docker, E2B, or Daytona | Docker or microsandbox support is partial | | Browser control | macOS, both modes; agent control partial | Built in | | Scheduled work | Not yet; triggers on pull request facts | Partial | | Platforms | macOS, Windows, Linux | macOS, Windows, Linux | ## Choose OpenWork when - You want one set of skills and connections to follow you across several agent clients. - Your team needs managed providers, shared connections, roles, policies, or hosted workspaces today. - Browser automation matters more than native document version history. - You already use OpenCode and want a desktop workspace built on the same primitives. ## Choose Tidebreak when - The work ends in a spreadsheet, deck, document, or PDF whose versions you need to inspect and restore. - You want several coding agents working in parallel without writing over one another, with a diff before anything reaches your branch. - You want generated code behind a supported sandbox boundary now. - You want the whole application under one permissive license and no product account in the path. ## Both are young OpenWork launched in 2026, and Tidebreak is pre-1.0. Both projects change quickly, so treat the feature rows as dated September 7, 2026. The durable distinction is simpler: OpenWork makes agent capabilities portable across people and tools; Tidebreak makes finished files and code changes inspectable across versions. --- Canonical: https://www.tidebreak.io/compare/openwork Updated: 2026-09-07 Site briefing for agents and crawlers: https://www.tidebreak.io/llms.txt --- # Tidebreak vs OpenWorker OpenWorker is the closest philosophical sibling Tidebreak has: local-first, open source, bring your own model or run one through Ollama, and judged on finished work rather than chat. The practical difference is the center of gravity. OpenWorker leans into connected apps, inbox and calendar work, and scheduled sessions. Tidebreak leans into documents: sandboxed code execution and versioned spreadsheets, decks, and memos on your disk. ## What OpenWorker is OpenWorker was announced in July 2026 by Andrew Ng and Rohit Prasad as an open-source agent that "doesn't just chat with you, but delivers finished work." It is MIT-licensed, free, and requires no account; the agent loop, history, and keys stay on your machine, and models are strictly bring-your-own, from the major API providers down to fully local through Ollama, switchable mid-conversation. Its strongest surface is connection to the tools work already lives in: more than twenty-five native connectors covering Slack, Gmail, Outlook, calendars, GitHub, Jira, Notion, and others, plus MCP, with Slack-triggered and scheduled background sessions on top. Writes, sends, and shell commands sit behind approval gates. If your working day is an inbox, a calendar, and a set of team tools, OpenWorker is aimed directly at it, and the people behind it have as much credibility as anyone in this field. We like this project. It argues the same things Tidebreak argues: that the agent should live on your machine, that the model should be your choice, and that the test is the finished work. ## Where the two lean differently **Connectors versus files.** OpenWorker reaches into your apps. Tidebreak reaches into your folders. Tidebreak supports MCP servers behind its approval gate, but it deliberately ships no OAuth connector catalog; its everyday interface to your data is documents, folder grants, code execution, and web search. That is a narrower surface, chosen so that the boundary stays inspectable: access exists per chat, granted through the system picker, and the model never sees an absolute path. **What comes out.** OpenWorker's documented outputs are documents, spreadsheets, reports, and actions taken in connected apps; slide decks are not among them today. Tidebreak produces spreadsheets, Word documents, PowerPoint decks, PDFs, charts, and small local apps, and wraps them in the machinery it was built for: every output versioned, restore append-only, and native viewers in the app so you review the real file before you send it. **How code runs.** Both projects gate risky actions behind approvals. Tidebreak goes a step further on execution: generated code runs inside a sandbox, the native macOS one by default or Docker, E2B, or Daytona, with a per-chat network policy. Overwriting a file in a connected folder always asks, whatever the permission mode. **Scheduling.** OpenWorker has scheduled and triggered background sessions. Tidebreak does not yet; a local scheduler is on the roadmap, and pretending otherwise would be the kind of claim these pages exist to avoid. **Hardware.** Tidebreak ships packaged builds for macOS (Universal), Windows, and Linux, including ARM64. OpenWorker's signed build targets Apple Silicon, with an unsigned Windows build and no Linux build at the time of writing. ## At a glance | | Tidebreak | OpenWorker | | --- | --- | --- | | Made by | Brightwave | Andrew Ng and Rohit Prasad | | License | Apache-2.0 | MIT | | Price | Free; you pay your model provider | Free; you pay your model provider | | Account | None | None required | | Models | API keys, ChatGPT plan sign-in, or local via Ollama | Bring your own keys, or local via Ollama | | App connectors | MCP servers; no OAuth catalog | 25+ native connectors plus MCP | | Scheduled work | Not yet | Yes | | Slide decks | Yes, with native preview | Not a documented output | | Output history | Versioned, append-only restore | No documented version history | | Code executes | Sandboxed: macOS sandbox, Docker, E2B, Daytona | On the host, behind approvals | | Platforms | macOS, Windows, Linux | macOS Apple Silicon; unsigned Windows build | ## Choose OpenWorker when - The work is operational: triaging an inbox, keeping a calendar honest, answering in Slack, moving tickets. - You want scheduled sessions running in the background today. - You want the shortest path from a connected app to an action taken in it. ## Choose Tidebreak when - The work ends in a file: a model in a spreadsheet, a deck, a memo, a report with its history intact. - You want code the model writes to run inside an isolation boundary, not just behind an approval prompt. - You are on an Intel Mac, Windows, or Linux, or you want to start from a ChatGPT plan instead of creating API keys. ## Both are young OpenWorker is weeks old as we write this, and Tidebreak is pre-1.0, so treat the details above as dated the day we published them. The split itself should last: apps and operations on one side, documents and their history on the other. Plenty of people will be well served by either, and some genuinely need both. --- Canonical: https://www.tidebreak.io/compare/openworker Updated: 2026-08-18 Site briefing for agents and crawlers: https://www.tidebreak.io/llms.txt --- # Tidebreak roadmap What's live. What's next. Tidebreak is in alpha; this covers the client and the wider agent infrastructure we are building around it. It is an honest list, not a launch calendar. Status labels: - Live: In the current build - Partial: Works, with limits we are honest about - Next: Specified or in progress, not shipped - Exploring: A direction, not a commitment ## The coworker on your machine The desktop app is the Tidebreak experience. It is where you sign in, grant a folder or a repository, pick a model, and get a file or a pull request back. Packaged builds ship for macOS, Windows, and Linux, including ARM64. The native sandbox, computer use, agent-driven browsing, and the managed LibreOffice install remain macOS-only. - macOS Universal app (Live). Intel and Apple Silicon, signed and notarized. Local-first, no Tidebreak account. State in SQLite on disk. - Windows and Linux installers (Live). A Windows installer plus Linux AppImage and Debian packages, from the same release as macOS, for x86_64 and ARM64. Release builds check for updates on every platform. The Windows installer is not Authenticode-signed yet. - Your ChatGPT plan, an API key, or Ollama (Live). Sign in with ChatGPT Plus or Pro, drop in a key for Anthropic, OpenAI, Gemini, xAI, Fireworks, Together, or OpenRouter, or point the OpenAI-compatible slot at Ollama. Switch mid-chat. - Four permission modes, per chat (Live). Plan, Ask, Auto, and Allow all. Overwriting a connected file always asks. Every MCP tool asks in Ask and Auto. - Projects and one inbox (Live). Group chats and code workspaces under a project with its own files. One inbox lists everything waiting on you, across both modes. - Voice input (Live). Dictate with a local whisper.cpp model downloaded on demand, or through OpenAI or Gemini transcription. - Headless CLI and MCP surface (Live). The same runtime as the desktop app: a local server, one-shot prompts with a permission mode, an MCP server over a workspace's files, and an MCP server another agent can use to drive chat and code mode. ## A file you can put your name on Outputs are a catalog, not a transcript. Same filename appends. Restore appends too. - Versioned outputs (Live). Work saved to output/ lands in the chat catalog with who produced each version and when. Delete is soft, with undo. - In-app preview (Live). Spreadsheets, Word, PowerPoint, PDFs, images, and interactive Plotly charts open without leaving Tidebreak. Source links jump to the page, line, sheet, or cell. - Append-only restore (Live). Restoring v2 from v5 produces v6. A wrong file is a recoverable event. - Edit in place (Live). Markdown and plain-text outputs are editable in the app. Save publishes a new version with the one you started from as its precondition. Nothing is overwritten. - Local apps that persist (Live). Ask once for a triage view and keep a sandboxed mini-app in the Apps library, with a manifest per revision. - Built-in document skills (Live). Word, PDF, PowerPoint, spreadsheets, and charts ship as packaged instructions. Add your own skills and prompts, or install a plugin from a pinned git URL, including plugins that bring their own MCP servers. - Sources per version (Partial). Each revision lists the sources the producing turn retrieved. Sentence-level citations on the file itself are still ahead. ## A change you can read before it lands Code mode is the second surface. You point it at a repository, pick an engine, and review every change before it reaches your branch. - Four engines, one app (Live). Claude Code, Codex CLI, opencode, and Grok CLI. Tidebreak downloads the pinned engine the first time you pick it and uses the engine's own sign-in. macOS, Windows, and Linux. - An isolated worktree per workspace (Live). Every workspace gets its own branch and git worktree under a root you can see and move, so agents never write over each other or your working copy. Archive a workspace and keep the branch. Release it and Tidebreak bundles the branch before dropping it. - Several agents in one workspace (Live). Keep several conversations in one workspace, each in its own tab, and run workspaces side by side. Fork any finished turn. Engine subagents show up as child rows with their own transcripts. Turns on a shared worktree run in sequence. - Per-turn diffs and native approvals (Live). Each turn is a checkpoint with its own diff. The same permission modes as work mode apply, and you can change the mode between turns. Deny with a reason and the agent reads it. - Pull requests without leaving the app (Live). Open or update a pull request, move a draft to ready, read checks and review comments, update a stale branch, resolve conflicts, and merge by squash, merge, or rebase. Stacked pull requests render as lanes. Merge only ever starts with you. - Watch and fix (Live). Hand the agent failing job logs, review feedback, or conflicts. Watch and fix survives an app restart, handles new failures as they land, and stops when the pull request is ready for you. - Triggers on pull request facts (Live). Durable rules that react to failed checks, conflicts, requested changes, a stale branch, ready-to-merge state, a merge, or a close. Each fires once per head commit. - Delivery and analytics (Live). One page tracks pull requests, workflow runs, and deployments across repositories. Analytics shows turn outcomes, tokens, prompt-cache traffic, estimated cost, and subscription usage. A command palette reaches all of it. - Terminals beside the agent (Live). Several terminals per workspace, as tabs or split panes, running in the worktree. Open the worktree in your own editor whenever you want to type. - Checkpoint restore (Next). Every turn already lands as a checkpoint. Rolling a worktree back to one is not built. ## How the work actually runs Same exec tool. Different backends. Credentials stay out of the sandbox. The model never sees an absolute path. - Native macOS sandbox (Live). The default execution backend on macOS, with per-chat network policy: offline, package installs, custom hosts, or open. - Local Docker (Partial). Available today, opt-in. Only a chat set to no network is fully enforced there. - E2B and Daytona (Live). Managed sandboxes for the same exec tool when you want the work off-box. - Folder grants (Live). A native picker, attached to that chat, with separate list, read, write, and run grants. Nothing about siblings or your home directory. Disconnect from one chat, or forget the folder everywhere. - Connected folders inside code execution (Partial). Host folders reach the sandbox on macOS. Managed providers cannot see them. - Queue and steer (Live). Queue follow-ups behind a live turn, or steer the turn while it runs, in both modes. The queue survives a restart. - Background agents (Partial). Parallel jobs from one turn, one level deep, up to four at a time. They check in for direction instead of stopping, you can resume or cancel them, and an admitted job survives a restart. Nothing keeps running after you close the app. - An in-app browser (Partial). macOS. Its own profile, never your everyday browser, with a reset path. In work mode, downloads land as outputs. In code mode, Claude Code, Codex CLI, and opencode get scoped browser tools over MCP: snapshots, clicks, forms, waits, responsive viewports, an inspect overlay. Windows and Linux agent control is not in the release yet. - Computer use (Partial). Screen capture and consent-gated app control. In the product on macOS, not finished. Unavailable on Windows and Linux. ## Search and connections Tidebreak can search the web, connect MCP servers to chats, expose REST APIs to the agent, and serve its own workspaces to other agents over MCP. There will not be a Tidebreak-owned OAuth catalog. - Web search and extract (Live). Exa, Tavily, Brave, Firecrawl, or self-hosted SearXNG, or the built-in search on Anthropic and OpenAI models. - MCP servers (Live). stdio or HTTP, added in Settings with save-and-verify, or imported from JSON. Every MCP tool counts as sensitive, so Ask and Auto both ask. - REST APIs (Live). Register operations from an OpenAPI document with an explicit allowlist. Credentials never reach the app or the model. - Tidebreak as an MCP server (Live). Expose a workspace's files read-only over stdio, or let another agent drive chat and code mode. - Organization-managed connected apps (Partial). Tidebreak signs in to a Model Gateway for hosted models and machines today. The managed catalog of MCP-connected apps behind that gateway is still being built. ## The system around the client Tidebreak is the open desktop surface. We are also building the shared control and access layers teams need when agents move from local files into company systems and production infrastructure. These products are in development. The capabilities are the commitment; their names and packaging are not final. - A governed model and app gateway (Partial). One self-hosted control plane for model providers and MCP-connected apps: identity, team grants, credentials, routing, usage, spend, and audit. Tidebreak already uses it for on-behalf-of inference and hosted machines. - Hosted machines (Partial). A code workspace can run on a Model Gateway machine that clones, commits, pushes, and works with pull requests as you. Server images, a compose stack, and a browser sign-in exist. The packaged desktop still embeds its own server and cannot point at a deployment. - Governed access to real infrastructure (Next). Policy-bound agent access to Kubernetes, PostgreSQL, cloud CLIs, SSH, and SaaS without distributing long-lived downstream credentials. - Sessions from Slack (Next). Start a code session from a Slack thread and have it run on a hosted machine, under the same approvals. The design is published and the machine side is in. The adapter ships as a gateway add-on, and approvals are still answered from the desktop. - Approvals from your phone (Next). An iOS and Android client that pairs with a gateway and supervises hosted sessions: live timelines, approvals, steering, follow-ups. Not in the app stores yet. - A fully supported coding workflow (Next). Watch and fix, triggers, and CI repair are in. What is still missing: a scheduler, checkpoint restore, and tests an agent is trusted to act on. ## After this alpha Tidebreak is pre-1.0. Schema changes are migrations now, not resets, but treat the local profile as replaceable until 1.0. This is what we are willing to say is next, and what is still only a direction. - Scheduled and recurring work (Next). Triggers already fire on pull request facts. A clock-driven scheduler on the same run journal, one-time, daily, weekly, is next. Not cloud cron. - Agent-driven browsing on Windows and Linux (Next). The in-app browser and its agent tools are macOS-only today. The other two platforms follow the same release bar. - Memory (Partial). An experimental memory layer is in the build, off by default under Settings. Turned on, conversations receive memory records and a memory tool. Shared and searchable memory are only a direction. - Citations on the file (Exploring). Sentence-level sources on the work product, so a claim can be walked back to the file it came from. - A plugin marketplace (Exploring). Plugins install from a pinned git URL today. A browsable catalog of instruction-only plugins is a direction, with explicit updates and no background auto-update. --- Canonical: https://www.tidebreak.io/roadmap Site briefing for agents and crawlers: https://www.tidebreak.io/llms.txt
