BrowserOS neo is a free, open-source browser for AI agents. It's a second Chromium that runs next to your normal Chrome. You import your Chrome profile in one click and connect Claude Code, Cursor, Codex, VS Code or Zed over MCP. The agent then gets its own tabs, signed into your accounts, while you keep working in your own window. The new-tab page shows which agent is running, on which site, and for how long. Most AI browsers want to replace the one you use every day. Neo doesn't bother. It's a spare window you hand to an agent so it can use Gmail, GitHub or Notion as you, and it saves sessions, screenshots and replays as files on your machine. It runs on macOS and Windows, is licensed under AGPL, and you bring your own model keys. If you were hoping for a smarter everyday browser, this isn't it.
BrowserOS neo gets the basics right. An agent doing real work needs a real browser session, with cookies, logins and single sign-on, but it shouldn't be using yours. A second Chromium profile with a control board and session replays is a better answer than a smarter address bar, and neo is the cleanest version of that idea available right now.
You get one-click import of your Chrome profile, MCP connections to the agents you already pay for, a live view of every running agent, and replays you can scrub through, saved as local files. The FAQ reads like it was written by someone who has watched agents fail. It says plainly what neo isn't (a cloud browser, or Chrome with a chatbot bolted on) and where your data goes, which is nowhere.
If you just want ChatGPT to browse for you, use the ChatGPT desktop app or its Chrome extension. If Comet is already your everyday browser, neo is a second install for a problem you've solved another way. And if you're not comfortable giving an agent your real cookies, stop here. That access is the whole point, and the whole risk.
It's one of the most honest, complete products in our list. Start it on a small, contained chore, and keep it away from your bank tab until it has earned more trust.
