Work with an AI agent inside a macOS web browser
Manage isolated browser profiles with local storage

Donut Browser manages separate browsing profiles for work that needs distinct cookies, logins, history, and browser fingerprints. Each profile can have its own proxy or WireGuard connection, and profile data stays on your computer by default. The open-source desktop app supports macOS, Windows, and Linux, with local profiles available without creating an account.
Profiles can be grouped, protected with a password, or cleared after use. Optional encrypted synchronization and a self-hostable sync server support access across devices, while API and AI-agent integrations provide ways to automate browser tasks. Donut suits users who need to organize multiple browsing contexts and control where profile data is stored, including teams sharing selected profiles.
