About BrowserOS

BrowserOS is an open-source browser designed to be used by AI agents. It is positioned as a secondary browser that sits alongside Chrome rather than replacing it, giving agents a place to carry out web tasks while you keep browsing normally. The project presents itself as an alternative to AI browsers such as ChatGPT Atlas, Perplexity Comet and Dia.

You can import logins, bookmarks and extensions from Chrome in one click so agents work with your real accounts, then connect agents such as Claude Code, Codex, Cursor or VS Code, which BrowserOS detects on your machine. Agents run in parallel in their own tabs. A live dashboard on the new tab page shows which site each agent is on, and every session is saved as a replayable video with a step-by-step action timeline.

Everything runs locally on your machine and the project is free under the AGPL-3.0 licence. Its topics point to local model tooling such as Ollama and LM Studio and it exposes tools through the Model Context Protocol. Typical tasks include posting to social media, clearing an inbox, updating a CRM or filing expenses. An enterprise offering is linked from the repository.
