About Donut Browser

Donut Browser is an anti-detect browser for macOS, Windows and Linux. It creates unlimited isolated browser profiles on your own machine, each with its own fingerprint, its own cookie store and its own proxy or WireGuard VPN. This page explains what it is, who makes it, and how it pays for itself.

What it is

Regular browsers leak the same canvas, WebGL, audio, font and TLS fingerprint across every tab and every user profile, so accounts that share a browser are trivial to link. Donut Browser puts each account in a separate browser identity. To a website, two profiles look like two different devices.

Everything runs locally. Profiles, cookies and logins are written to your own disk and are never sent to our servers. Cloud backup is optional, off by default, end-to-end encrypted, and can be self-hosted from the same open-source sync server we run.

Who builds it

Donut Browser is built by one maintainer, in public. The desktop application is open source under the AGPL-3.0 licence and every line of it is on GitHub, so the claims on this site can be checked against the code rather than taken on trust.

One component is not open source: the Wayfern browser engine, a Chromium fork, ships as a binary. That is stated plainly here because it is the kind of detail a comparison page usually leaves out.

How it is funded

There is no venture funding, no advertising and no data business. The free plan is funded by the paid plans, and the paid plans sell capacity and convenience: cloud profile backups, remote sessions, team seats, the browser-launch API, and a commercial licence for companies that cannot take on AGPL-3.0 obligations.

Nothing is funded by your data. The application collects no telemetry, and this website uses cookie-free analytics that record no IP addresses and no personal data.

The company

Donut Browser is operated by Internet Technology Services LLC, a company registered in the United States. Its services run on infrastructure in the European Union. The same entity is named in the privacy policy and the terms of service.

How to reach us

Support, security reports, press and licensing questions all go to the same address, and bug reports are best filed in public on GitHub so other people can find them.
