Donut Browser

Donut is an anti-detect browser that runs locally on the user's machine, providing unlimited isolated browser profiles with per-profile fingerprints, proxies, and WireGuard VPN. It solves the problem of managing multiple online identities securely without cross-profile data leakage. It targets IT teams, security teams, developers, and operations professionals in small to large organizations, as well as individual power users. It is positioned as an open-source, local-first alternative to cloud-based anti-detect browsers, with zero telemetry and self-hostable sync.
