## 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.

Why incognito fails

## Same device, same fingerprint. Drag to see the difference.

Incognito clears cookies, not your fingerprint. On the same machine every private window shares one identical hash, so five accounts still look like one person. Drag the divider to compare with Donut Browser.

Incognito, same device Donut Browser

On the left, incognito hands every account the same fingerprint hash, so a tracker links them instantly. On the right, Donut Browser gives each profile a unique, isolated identity that cannot be tied back together.

Features

## Key Features

01

### 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.

02

### 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.

03

### 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.

04

### 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.

05

### 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.

06

### 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.

Comparison

## 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 |

## Questions, answered.

### 01 How do I prevent browser fingerprinting?

Blocking fingerprinting APIs breaks sites and flags you as suspicious. The reliable way is to randomize the fingerprint: give each browsing session a different, realistic-looking device. Donut Browser does this automatically: every profile gets a unique Canvas, WebGL, AudioContext, font list, hardware profile, User-Agent and Client Hints, so sites see a different real device each time instead of a hardened privacy browser.

### 02 How can I test my browser fingerprint?

Use Pixelscan, IPHey, CreepJS, BrowserLeaks and fingerprint.com. Open each in a fresh Donut Browser profile and you will see different Canvas hashes, WebGL renderers, AudioContext values, fonts and User-Agents per profile, and no "automation/bot" flags. Profiles pass Pixelscan (including mobile), IPHey, CreepJS and BrowserLeaks, and fingerprint.com Pro does not detect them as bots.

### 03 Does incognito mode stop fingerprinting?

No. Incognito only clears cookies and history when you close the window. Your Canvas, WebGL, AudioContext, fonts, hardware and User-Agent are identical to your normal browser, so trackers still recognize you across incognito sessions. Donut Browser changes the fingerprint itself, which is what incognito does not do.

### 04 What is the best way to stop tracking by canvas fingerprinting?

Spoof the Canvas output per profile with a realistic, consistent hash rather than returning random noise (which sites detect). Donut Browser's Canvas fingerprint blocker pairs Canvas spoofing with matching WebGL, AudioContext and font lists so the whole fingerprint stays coherent and undetected.

### 05 How is this different from Tor Browser?

Tor Browser tries to make every user look identical, which makes Tor users very easy to identify as Tor users, and many sites block them outright. Donut Browser is a Tor browser alternative that goes the opposite way: each profile is a different, normal-looking device. You blend in instead of standing out, and you can still route any profile through a VPN or proxy if you want network-level anonymity.

### 06 How is this different from Brave or DuckDuckGo?

Brave and DuckDuckGo block trackers inside a single browser identity (useful), but you are still one fingerprint across everything you do. As a Brave alternative, Donut Browser lets you spin up unlimited identities, each with its own fingerprint, cookie jar, storage and optional proxy/VPN. It is a different model: separation of identities, not just blocking of trackers.

### 07 What fingerprint parameters does Donut Browser spoof?

Over 50 parameters: Canvas and WebGL rendering output, AudioContext (sample rate, latency, channel count), screen dimensions and color depth, hardware concurrency and device memory, User-Agent and Client Hints (brand, platform, architecture), installed fonts, timezone and language, WebRTC addresses, media devices (microphones, webcams, speakers), battery status, navigator properties (plugins, MIME types, platform) and accessibility preferences. Values are generated to be internally consistent so the fingerprint matches a plausible real device.

### 08 Does a VPN stop browser fingerprinting?

No. A VPN only changes your IP address. Sites can still identify you via Canvas, WebGL, AudioContext, fonts and User-Agent; your fingerprint is identical whether you use a VPN or not. Use Donut Browser's anti-fingerprint engine for the browser layer and add the built-in per-profile WireGuard or SOCKS5 proxy for the network layer.

### 09 Does Donut Browser collect any data?

No. Zero telemetry, no analytics, no crash reporters, no usage tracking. All profile data is stored locally. The Donut Browser app is open source under AGPL-3.0 on GitHub; you can verify this yourself.

### 10 Can I use Donut Browser for everyday browsing?

Yes. Create one profile per activity (personal, banking, shopping, social, work) and each one is an isolated identity with its own fingerprint and storage. Profiles persist across launches so you stay logged in.

### 11 Can I run automation through anti-fingerprint profiles?

Yes. Donut Browser exposes a local API so you can drive profiles with Puppeteer, Playwright or your own scripts while keeping the spoofed fingerprint and per-profile proxy. See the automation use case for the full setup.
