A second browser, just for your AI agents. Import your logins from Chrome in one click, connect Claude Code, Codex, 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.
BrowserOS neo is not a Chrome replacement. It is a secondary browser that sits next to Chrome, made friendly to agents.
Get started
1. Install BrowserOS neo
brew tap browseros-ai/tap
brew install --cask browseros-neo
Prefer a direct download? Grab it for macOS, Windows, or Linux x64 (AppImage · DEB).
2. Import from Chrome
One click brings over your logins, bookmarks and extensions. Your agents work with your real accounts from the first task.
3. Connect your agent
BrowserOS neo finds Claude Code, Codex, Cursor, VS Code, OpenClaw and Hermes on your machine. Connect any of them with one click.
4. Give it a task
From your agent, not from the browser:
Book me the cheapest flight to London.
Watch it happen live in your new tab, or replay it later.
What can your agents do?
Anything that needs a logged-in browser:
- Post content to your social media (LinkedIn, Twitter/X), queue posts, pull engagement numbers
- Clear your inbox, unsubscribe from junk email
- Update your CRM, file expenses, pull reports from internal tools
Key features
Live dashboard
Your new tab shows every agent working right now: which site it's on, what it's doing, how far along. Docs

|
One-click connect
Automatically connects to every harness. We built tools optimized for web use! Docs
|
|
Replay every session
Every 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 your logged-in accounts, 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. For the same task, BrowserOS neo uses fewer tokens than the alternatives, such as Claude's Chrome extension or the Codex browser.
- Local-only, privacy-first. 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 agent-browser spin up a fresh Chrome subprocess with no logins. Great for CI, useless for real work which requires your logged-in state like "read my inbox." BrowserOS neo imports your logins with one click and persists them across sessions.
- Not a cloud browser. Cloud browsers (like browser-use, browserbase) run in a datacenter, so logging into your accounts is a pain, and sites like Twitter and LinkedIn block you because you are on a datacenter IP. 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: Claude Code, Cowork, Codex, Cursor, and others.

BrowserOS, the AI browser for humans
A Chromium fork with an AI agent built into every new tab, for when you are the one browsing. Bring your own AI keys or run everything locally with Ollama.

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, Hermes, OpenClaw and Antigravity connect with one click.
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 and BrowserOS run on macOS, Windows, and Linux. Neo's Linux builds are x64. System requirements match Google Chrome.

For developers
Both browsers ship from this monorepo. Two main subsystems: the browser (Chromium fork, C++ and Python) and the agent platform (TypeScript and Rust).

BrowserOS 是一个单一代码仓库（monorepo），包含两款开源的 Chromium 分支浏览器：'BrowserOS neo'，一款由你的 AI 智能体操控的辅助浏览器（通过 MCP 连接 Claude Code 或 Codex 等工具）；以及 'BrowserOS'，一款由你自己用 AI 智能体操作的浏览器，每个新标签页内都内置了 AI 智能体。
