BrowserOS

BrowserOS is a Chromium fork built for AI agents to drive. The neo variant runs as a second browser where Claude Code, Cursor, or any MCP-compatible agent does web tasks in its own tabs using your logged-in accounts, with every session recorded and replayable as scrubbable video. The full browser variant is a daily driver with an agent built in. AGPL, free, bring your own model keys.

Setup is signed installers for macOS and Windows, with Linux on the full browser. There's no BrowserOS subscription; cost is whatever your model provider charges, and local models via Ollama bring that to zero. Building from source is a Chromium build, so plan on hours, not minutes.

This is for developers already using coding agents who want them doing authenticated web work, pulling data from dashboards, filling forms, without handing credentials to a cloud service. The proprietary comparisons are ChatGPT Atlas, Perplexity Comet, and Dia.

The catch is trust and blast radius. You're giving a young third-party Chromium fork your live sessions, and an agent holding your cookies can act as you. Chromium forks also historically lag upstream on security patches. Keep it away from anything you can't afford to have clicked.
