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
- 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?
