◈ GPU Detection

What Is My GPU?

Detect your GPU model using WebGL. See your graphics card renderer, vendor, and WebGL version. No software needed.

How GPU detection works in a browser

Browsers expose GPU information through the WebGL API, specifically via the WEBGL_debug_renderer_info extension. This returns the unmasked renderer and vendor strings — the actual GPU model name.

Some browsers (like Firefox with enhanced privacy settings) may block this information to prevent fingerprinting. In that case, we show the masked WebGL renderer string instead.

How WebGL reveals your GPU

The WebGL WEBGL_debug_renderer_info extension exposes your actual GPU renderer and vendor strings, giving the real model name without any software install. This is how sites detect your specific graphics card directly through the browser.

GPU detection and privacy

Privacy browsers like Firefox with strict settings block this extension to prevent fingerprinting. GPU info contributes to browser fingerprinting, a method of identifying users across sessions without cookies. If you see renderer info blocked, your browser is protecting you from this tracking technique.

Can a website detect my GPU? +
Yes, via the WebGL debug extension. Privacy browsers like Firefox can block this to prevent fingerprinting.
What is WebGL? +
A browser API giving web pages direct GPU access for 2D and 3D rendering, used in games, data visualizations, and interactive maps.
What does renderer info blocked mean? +
Your browser privacy settings prevent GPU identification. This protects against fingerprinting but prevents detecting your GPU model.
Does my GPU affect browser performance? +
Yes. A strong GPU improves CSS animation smoothness, WebGL rendering, hardware video decoding, and performance on graphics-heavy pages.
