BrowserOS
BrowserOS is a desktop web browser for macOS that lets AI agents use your logged-in accounts while you watch, replay, and manage their browser sessions.
What is BrowserOS?
BrowserOS is a native desktop web browser for macOS built to let AI agents perform real browsing tasks using the accounts and sessions you already use. It is designed for people who want tools such as Claude Code, Codex, Cursor, and other MCP-compatible agents to open tabs, navigate sites, click through workflows, and complete web tasks in a separate browser environment. The app supports connecting compatible agents, running several agent-driven sessions at once, and replaying past sessions so you can review what happened. BrowserOS also emphasizes local operation, with session history, screenshots, replays, and settings stored on your machine rather than in a hosted dashboard. Published by Nikhil Venkat Sonti, it fits workflows where users want a browser dedicated to AI-assisted automation without replacing their main day-to-day browser habits.

Safety overview
Status: Mostly safe
BrowserOS is intended to control web sessions on your behalf, so it may access sites where you are already signed in and may store browsing-related data such as history, screenshots, and replays on your Mac. That behavior is consistent with its purpose, but it also means you should be thoughtful about which accounts you let an AI agent use and review sensitive actions before relying on them. If you use it for work, finance, shopping, or admin tasks, keep an eye on session playback and avoid giving agents more access than needed.
Recommendation: Keep BrowserOS if you actively use AI agents to handle browser-based tasks or want a separate browser for that workflow. If you do not use agent-driven browsing, you can remove it without affecting macOS, though you may lose local session history, screenshots, and replay data saved by the app.
