Donut Browser

Donut Browser is an open-source, anti-detect browser built by a single independent maintainer that lets users run unlimited isolated browser profiles, each with real per-profile fingerprints, and per-profile proxy or WireGuard VPN configuration, with all data stored locally on the user's device. It offers isolated storage and extensions per profile, per-profile fingerprinting across canvas, WebGL, audio, fonts, and timezone, HTTP/SOCKS proxy and WireGuard VPN support per profile, and profile grouping and organization tools. Donut Browser includes a local REST API and MCP server integration for automation, operates with zero telemetry, and is fully open source under the AGPL-3.0 license, cross-platform on macOS, Windows, and Linux. Pricing is freemium: the core app is free forever with no account needed, offering unlimited profiles and proxy support, while paid Pro plans unlock browser automation APIs, MCP tooling, self-hostable cloud sync with end-to-end encryption, team collaboration, and commercial licensing. The latest release is version 0.29.6.
