# Your WebGL fingerprint, checked for consistency

Websites can read your graphics card's identity and capabilities through WebGL, and render hidden images that hash differently on every GPU. This test shows everything WebGL reveals about your machine and checks whether it is consistent, spoofed or broken.

## What WebGL reveals

WebGL gives websites a direct line to your graphics stack: the GPU vendor and model, driver-dependent capability limits, supported extensions and pixel-exact rendering output. Any page can read all of it without asking permission.

02

## Why consistency matters

Blocking WebGL or randomizing its output doesn't hide you; it makes you the browser with impossible graphics. Detection scripts cross-check the renderer against your platform, the parameters against the claimed GPU, and repeated renders against each other. [Donut Browser](https://donutbrowser.com/#download) keeps every profile's WebGL believable and internally consistent.

## Every profile its own identity

Donut Browser is a free, open-source anti-detect browser. Each profile gets its own consistent fingerprint, IP and proxy, so the signals on these tools can't tie your accounts together or back to you.

## Questions, answered.

### 01 What is a WebGL fingerprint?

It's an identifier built from what WebGL exposes about your graphics stack: the vendor and renderer strings, dozens of capability parameters, the extension list and a hash of a rendered image. Together they are stable for your device and readable by any website.

### 02 What does spoofed WebGL look like?

Typical signs are a renderer that doesn't match the operating system, capability values no real GPU of that model would report, WebGL 1 and WebGL 2 disagreeing with each other, and rendered images that change between identical draws. This tool checks for all of them.

### 03 Should I disable WebGL?

Disabling it breaks sites and makes your browser rarer, not more private. A consistent, believable WebGL identity per profile is more effective. Donut Browser provides exactly that.
