Donut Browser0.31.3

Donut Browser lets you operate multiple isolated browser identities on one computer, keeping each account in its own local profile. It is an anti-detect browser with unlimited profiles, individual fingerprints, separate storage and network settings, and per-profile proxies. Sellers can run eight accounts at once, for example, checking inventory and changing prices while each account presents a different device fingerprint, time zone and proxy exit.

Canvas, WebGL, audio, fonts and timezone signals remain consistent inside a profile while differing between profiles. Profiles accept HTTP, HTTPS, SOCKS4 and SOCKS5 proxies, along with basic authentication, IP allowlists and dynamic proxy URLs; a .conf file can also define routing so the country, ASN and timezone match. Users can assign links to particular profiles, making calendar invitations, dashboards and advertising platforms open in the intended identity, and existing profiles can be brought into Donut.

The desktop app supports grouping and tagging, a local REST API, and profile-driven workflows without a cloud dashboard or an open browser tab. Pro adds browser-automation APIs, MCP tooling, remote MCP access for AI agents, and end-to-end encrypted cloud backup for teams and high-volume operators; an optional Docker sync server can synchronize profiles, proxies and groups across devices using a password known only to the user. Donut keeps profile data on the machine unless the user directs it elsewhere, and includes no tracking, device fingerprinting or analytics SDK.

The freeware release, currently version 0.31.3, runs on MacOS with Apple Silicon, including M1 through M4 and newer Macs, while Macs from before the Apple Silicon transition have a supported build; brew upgrade handles updates. Donut is open-source and also available for Windows and Linux, making it useful for multi-account social work, client management and other persistent identity-based browser tasks.
