Anti-Fingerprint Browser
Stop sites from fingerprinting you. Canvas, WebGL, WebRTC and user-agent spoofing built in, an open source Tor and Brave alternative.
Stop browser fingerprinting at the source
Modern trackers do not need cookies. Canvas, WebGL, AudioContext, fonts, screen, hardware, timezone and client hints combine into a fingerprint that is unique for over 90% of users, and it follows you across incognito, cleared cookies and even VPNs.
Donut Browser is a fingerprint randomizer, not a blocker. Each profile gets a realistic, internally consistent fingerprint across 50+ parameters (Canvas, WebGL, AudioContext, WebRTC, fonts, User-Agent and Client Hints) so you look like a different real device every time instead of a flagged "privacy browser".
It is open source under AGPL-3.0 with zero telemetry: no analytics, no usage tracking, profile data stays on your machine. Profile manager, API and sync service are all on GitHub for anyone to audit.
Block fingerprinting in under 2 minutes
Free, open source, and verified against Pixelscan, IPHey, CreepJS and BrowserLeaks. No account, no telemetry.
Key Features
Canvas fingerprint blocker & WebGL fingerprint protection
Per-profile Canvas, WebGL and AudioContext spoofing with internally consistent values. Passes Pixelscan, IPHey, CreepJS and BrowserLeaks instead of just blocking the API and getting flagged.
WebRTC leak protection
Blocks WebRTC IP leaks per profile and spoofs local IPv4/IPv6 so your real address never escapes, even when your VPN is on.
Spoof user agent & client hints
User-Agent, Sec-CH-UA brand/platform/architecture, navigator.platform and accept-language are all spoofed together so headers and JS never disagree.
Per-profile VPN & proxy
Bind WireGuard or HTTP/SOCKS5 proxies to each profile, so each spoofed identity also has its own IP and geo; no global VPN required.
Isolated identities, no cross-site tracking
Cookies, localStorage, IndexedDB, cache and history are fully isolated per profile. Banking never meets social; pair this with the multi-account workflow for separate identities at every layer.
Open source privacy browser
AGPL-3.0 on GitHub with zero telemetry. Audit the profile manager, API and sync yourself, unlike closed-source anti-detect competitors.
Donut Browser vs Tor, Brave & regular browsers
How an anti-fingerprint browser compares to Tor, Brave, DuckDuckGo and incognito mode for stopping browser fingerprinting and tracking.
| Feature | Donut Browser | Regular Browser |
|---|---|---|
| Canvas / WebGL / AudioContext spoofing | Realistic, consistent values per profile: passes Pixelscan, IPHey, CreepJS, BrowserLeaks | Same Canvas/WebGL/Audio hash every session: trivial to fingerprint |
| User-Agent & client hints spoofing | UA, Sec-CH-UA brand/platform/arch, navigator.platform and language spoofed together | Fixed UA; client hints leak the real OS and CPU even if you change the UA string |
| WebRTC leak protection | Per-profile WebRTC blocking and local IP spoofing: real IP never exposed | WebRTC leaks the real IP even with a VPN enabled |
| Multiple identities | Unlimited profiles, each a distinct fingerprint + cookies + storage + optional proxy | One identity per browser; incognito just resets cookies |
| Cross-session tracking | Impossible: every profile is a different device to the network | Trivial via fingerprinting, even in private/incognito mode |
| Per-profile VPN / proxy | WireGuard, HTTP, HTTPS, SOCKS4, SOCKS5 bound per profile | System-wide VPN only; one IP for everything |
| Telemetry | Zero telemetry, verifiable in the open source app | Usage data, crash reports and browsing history commonly collected |
| Source code transparency | AGPL-3.0 on GitHub: profile manager, API and sync are auditable | Closed source: you must trust the vendor |
| Detected as a privacy browser? | No: looks like a normal Chromium device, not flagged like Tor | Tor is detectable and often blocked; Brave/DDG ship a known fingerprint |
