About BrowserOS
BrowserOS is an open source agentic browser, written in TypeScript under AGPL 3.0, that puts AI agents inside a real Chromium browser on the user's own machine so they can work with real logged in accounts, and it is aimed at people who already use an agent harness such as Claude Code, Codex, Cursor, or any MCP agent and want that agent to handle web tasks instead of a sandbox.
