Open-sourceFree · BrowserOS is described as completely free and open source. Some external cloud providers may charge based on usage, and certain models offer free tiers, but the product itself is free/open-source.

BrowserOS is an open-source, privacy-first browser that runs AI agents locally to automate web tasks. It positions itself as a Chrome-like browser with built-in AI agents and extensive app integrations for local, end-to-end automation.

A Chromium-based open-source browser that ships with built-in AI agents running locally on the user's machine. Users describe tasks in natural language and the agent handles clicking, typing, and navigating, browsing the web, reading local files, and automating multi-step workflows within the browser. It supports multiple AI model providers (e.g., Claude, Gemini, OpenAI, Kimi) and can run local models via Ollama/LM Studio. It includes 40+ built-in MCP (message-crafted protocol) integrations to apps like Gmail, Slack, Notion, Calendar, etc., and can connect to custom MCP servers. Features include scheduled tasks, a pre-installed MCP server, and the ability to drive external tools via terminal through Claude Code or Gemini CLI. It emphasizes privacy with sandboxed agents and offline/local execution where possible, and is available on macOS, Windows, and Linux as a free/open-source product.

Who it’s for: Businesses and individual power users who want an open-source, privacy-conscious browser with built-in AI automation and a strong ecosystem of app integrations and local-first execution.
