BrowserOS · Redwood City, California, United States · founded 2024
What it is
BrowserOS is a free, open-source Chromium-based browser for desktop that uses AI agents to carry out web tasks from natural-language instructions. Its agents can click, type, navigate, fill in forms, extract data, and run multi-step workflows. Chat Mode answers questions about the page you are viewing; visual Graph Mode for repeatable workflows is marked as coming soon.
BrowserOS supports Gemini, Claude, and OpenAI, as well as local models through Ollama or LM Studio. The maker lists 40+ app integrations through MCP, including Gmail, Slack, Notion, and Calendar, and 53 built-in browser tools. An included MCP server can connect with Claude Code, Gemini CLI, or Codex. As a Chromium fork, it supports Chrome extensions and importing Chrome bookmarks, passwords, and settings.
Browsing data stays on the device unless cloud syncing is enabled; it is off by default, and synced activity is encrypted on BrowserOS servers. BrowserOS says it does not store or log AI prompts or responses, though providers may handle submitted data under their own policies. It runs on macOS, Windows, and Linux and is licensed under AGPL-3.0.
For and against
For
- Free and open source under AGPL-3.0
- Agents handle clicks, forms, and multi-step tasks
- Supports Chrome extensions and imports browser settings
- Local models available through Ollama or LM Studio
Against
- Graph Mode is marked as coming soon
- Local LLMs are not yet powerful enough for Agent Mode
- Default AI model has limited daily usage
- Cloud AI provider usage may cost extra
The verdict
BrowserOS combines Chromium browsing with agents for automating web tasks, plus broad extension and model support. Keep in mind that Graph Mode is not yet available, and local models are not ready for Agent Mode.
Who it suits
BrowserOS suits desktop users who want AI agents to automate browser tasks or build workflows, and developers who use an MCP server. It also fits users looking for an open-source browser with local-model options.
