What it is
BrowserOS is an open-source Chromium fork with an AI agent built into every new tab. It supports 20+ built-in tools and 40+ app integrations, with local operation options via Ollama or LM Studio. It ships two products from the same repo: BrowserOS neo (the agent-driven browser for AI tasks) and BrowserOS (the AI-enabled regular browser).
How it works
The architecture comprises a browser component (Chromium fork) and an agent platform, including MCP server and various UI/back-end components. BrowserOS neo enables MCP connections to drive agents across tabs, while BrowserOS provides both normal browsing and integrated AI capabilities. The components are organized into packages such as:
- packages/browseros: Chromium fork, build system, patches, signing
- apps/claw-server-rust: MCP backend and API for the dashboard
- apps/server: Bun server exposing MCP tools and the AI agent loop
- apps/app: BrowserOS extension UI
- apps/cli: Go CLI for terminal control
