BrowserOS

BrowserOS is a local open-source browser that enables AI agents to perform tasks using the user's existing logged-in accounts and browser sessions.

BrowserOS neo is an open-source browser that allows AI agents to navigate the web, log in, and interact with websites using existing user sessions. The browser runs locally on the machine, keeping browsing data, session history, and video replays stored on the disk rather than in the cloud. It supports integration with agents like Claude Code, Cowork, Codex, Cursor, and any tool that utilizes the Model Context Protocol. Users can watch agents operate in real time through isolated tabs, with every session saved as a scrubbable video for auditing and verification. By utilizing compact page snapshots instead of raw HTML, the browser reduces token usage and batch-processes actions to minimize API costs. The software operates as a secondary browser, preventing agents from interfering with the user's primary web windows or open documents.
