BrowserOS neo: the browser for your agents
What is BrowserOS neo? A second browser, just for your AI agents. Import your logins from Chrome in one click, connect Claude Code, Codex, Cursor, or any MCP agent, and hand off your web tasks. Agents run in parallel in their own tabs. You watch live, or replay any session like a video.
Your AI is smart, but it can't press the buttons. Ask it to book a flight or reply to an email, and it stops at the login screen. BrowserOS neo fixes that.

Get started
- Install BrowserOS neo and import from Chrome in one click: logins, bookmarks, extensions.
- It finds your agents. Claude Code, Codex, Cursor, VS Code, Zed, OpenCode, and Antigravity connect with one click. Anything that speaks MCP connects with a URL.
- Give it a task from your agent. "Book me the cheapest flight to London." Watch it live from your new tab, replay it later.
What can your agents do?
Anything that needs a logged-in browser:
- Book flights and restaurants
- Unsubscribe from junk email
- Find apartments and message landlords
- Reply on X, queue posts, pull engagement numbers
- Update your CRM, file expenses, pull reports from internal tools
Key features
Live dashboardYour new tab shows every agent working right now: which site it's on, what it's doing, how far along. Docs |  |
One-click MCP connectOne endpoint, every harness. Seven AI tools set up with a single click. Docs |  |
Replay every sessionEvery session is saved as a scrubbable video on your disk with a step-by-step action timeline. Rewind and see exactly what happened. Docs |  |
- Your logins. Agents automate your real work using the sessions you already have, not a blank sandbox. How it works
- Parallel agents. Fire off several tasks at once. Each agent works in its own tab while you keep browsing.
- Fewer tokens. Agents get compact page snapshots instead of raw HTML and batch actions in one call. Same automation, smaller bills.
- Local-only. Sessions, screenshots, and history live under
~/.browserclaw/and never leave your machine. Privacy
Why BrowserOS neo over the alternatives?
- Not a headless driver. Playwright and browser-use spin up a fresh Chrome subprocess with no logins. Great for CI, useless for "book my flight" or "read my inbox." BrowserOS neo is the browser your logins already live in.
- Not a cloud browser. Browserbase and Browser Use Cloud run your agent's session on someone else's infrastructure. Your prompts and session tokens pass through their servers. BrowserOS neo runs on your machine, on
127.0.0.1. - Not a locked-in AI browser. Atlas, Comet, and Dia only work with their own AI. BrowserOS neo works with the agents you already use and pay for.
BrowserOS: the AI browser for humans
What is BrowserOS? BrowserOS is a free, open-source Chromium fork with an AI agent built into every new tab. Ask it to summarise a page, click through a flow, extract data, or run a scheduled task, and it uses 20+ built-in tools plus 40+ app integrations to get the work done. Bring your own AI keys or run everything locally with Ollama.
Every AI browser today asks you to sign into their cloud and hand over your data. BrowserOS is the one that doesn't. Same daily browser you already use, with a helpful agent one keystroke away.

Get started
- Download and install BrowserOS: macOS · Windows · Linux (AppImage) · Linux (Debian).
- Import from Chrome in one click. Bookmarks, passwords, extensions all carry over.
- Connect your AI provider. Claude, OpenAI, Gemini, ChatGPT Pro via OAuth, or local models via Ollama or LM Studio.
Key features
BrowserOS agent in actionAsk it in plain English. 20+ built-in tools plus 40+ app integrations (Gmail, Slack, GitHub, Linear, Notion, and more). Docs |  |
Install as MCP and control from claude-codeTurn BrowserOS into an MCP server and drive it from Claude Code, Cursor, or any MCP client. Docs | |
Use BrowserOS to chatChat about the current page from the side panel. Summarise, ask questions, transform what you're reading. Docs | |
Use BrowserOS to scrape dataPoint the agent at a page, tell it what to pull, and get structured data back. Docs |
- Cowork with files. Combine browser automation with local file operations in one session. Docs
- Scheduled tasks. Run agents on autopilot: daily, hourly, or every few minutes. Docs
- Bring your own AI. 11+ providers, or fully local with Ollama and LM Studio. Provider list
- Real ad blocking. uBlock Origin with full Manifest V2 support. Docs
Why BrowserOS over the alternatives?
- Not Chrome with an AI extension. Extensions can't touch the browser chrome, can't run scheduled background tasks, can't ship the 20+ built-in tools that the agent uses natively. BrowserOS builds the agent into Chromium itself.
- Not Comet, Atlas, or Dia. Those AI browsers route your prompts through their cloud with their model. BrowserOS runs on your machine with your AI keys. Your data stays yours.

FAQ
What's the difference between BrowserOS neo and BrowserOS?
BrowserOS neo is a browser your AI drives. BrowserOS is a browser you drive, with an AI agent built in. Both ship from this repo and run side by side. Keep your daily browser, and let agents work in neo.
Which AI tools work with BrowserOS neo?
Any AI that speaks MCP. Claude Code, Codex, Cursor, VS Code, Zed, OpenCode, and Antigravity connect with one click; Claude Desktop connects via a drop-in extension; anything else connects with a URL.
Does my AI share my logins?
Yes, and that's the point. Agents drive BrowserOS neo using the sessions you already have, so they automate your real work instead of poking a blank sandbox. Every agent's tabs sit in their own colored tab group so you can always see whose is whose.
Does anything leave my machine?
Your sessions, screenshots, history, and settings live under ~/.browserclaw/ and never upload. BrowserOS neo sends anonymous product-usage events (agent connect/disconnect, version, OS) to help us improve the app; it never sends URLs, page content, prompts, tool results, or screenshots. Off with one toggle in Settings. Full policy.
Do my Chrome extensions and bookmarks work?
Yes. Both browsers are Chromium forks, so Chrome extensions work and your bookmarks, passwords, and settings import in one click.
What platforms are supported?
BrowserOS neo runs on macOS and Windows. BrowserOS runs on macOS, Windows, and Linux. System requirements match Google Chrome.

We'd love your help making BrowserOS and BrowserOS neo better. See the Contributing Guide for details.
- Agent development (TypeScript/Go): see the agent monorepo README for setup.
- Browser development (C++/Python): requires ~100GB disk space. See <code class="ra0-md-code">packages/browseros</code> for build instructions.
