What it is
Donut Browser is an open-source anti-detect browser. It provides unlimited browser profiles, an anti-detect Chromium engine, DNS ad-blocking, per-profile proxy and VPN support, a local API and MCP for integration, profile groups, and import/export of cookies and extensions. It also offers a default browser setting, cloud self-hosted sync, end-to-end encrypted sync option, and zero telemetry.
How it works
The project uses an anti-detect Chromium engine built on Wayfern to spoof fingerprint data. It supports per-profile DNS blocking, per-profile proxies (HTTP, HTTPS, SOCKS4, SOCKS5) with dynamic URLs, per-profile VPN via WireGuard configurations, and a REST API plus Model Context Protocol server for automation and integration. Profiles, groups, and import/export flows enable management of cookies and extensions.
