Who makes Yab

Me, Serafim Korablev (@korablev). It’s one person and a lot of AI agents. About 3,000 people use Yab every day.

Your data

Yab has no account. Your tabs, history and settings stay on your Mac, and passwords live in the macOS keychain. Sync is end-to-end encrypted: our server can’t read it. What little leaves your Mac is on the privacy page.

Security

Every build is signed and notarized by Apple. Chromium tabs get Chromium’s security fixes as they come out.

Open source

The browser isn’t open source yet. The MCP server and plugins are. Found a security problem? Send it through Feedback in Yab or DM me on X, and I’ll answer myself.
