WebGL report
Web Graphics Library can expose graphics driver strings (vendor/renderer). Useful for debugging; also relevant to fingerprinting discussions.

WebGL renderer
This reads WebGL vendor and renderer strings from your browser. They can add uniqueness to a device fingerprint. The values stay in your browser session for display on this page.
What WebGL exposes
WebGL lets browsers render GPU-accelerated graphics. Along the way, some environments expose vendor and renderer strings that help debug graphics issues and that researchers discuss in fingerprinting conversations.
If renderer is blocked or WebGL is unavailable, your browser or extensions may be limiting access—common in stricter privacy setups.
Using the report
Developers use renderer strings to reproduce GPU-specific bugs. Everyday users mainly need this when troubleshooting black screens or driver mismatches.
You can disable WebGL in advanced browser settings, which may break maps and games. Pair with canvas fingerprint if you are auditing client-side signals.

Frequently Asked Questions
What is WebGL?
WebGL is a browser Application Programming Interface for hardware-accelerated 3D and 2D graphics. It can expose vendor and renderer strings for your graphics stack, which is useful for debugging and relevant to fingerprinting.
Why is renderer blocked?
Some browsers require a debug extension or reduce detail for privacy. We show what your browser allows.
How do I enable or disable WebGL?
- Chrome/Edge:chrome://settings/system → use hardware acceleration when available; or chrome://flags → search WebGL.
- Firefox:about:config → webgl.disabled (true disables WebGL).
- Safari:Settings → Feature Flags / Develop → Experimental Features → WebGL.
- Note:disabling WebGL can break maps, games, and 3D sites.

Is WebGL related to fingerprinting?
Yes. Vendor and renderer strings can add uniqueness to a browser fingerprint. Privacy modes may reduce or hide that detail.
What if WebGL is unavailable?
Hardware acceleration may be off, WebGL may be disabled, or the browser may block the Application Programming Interface. Games, maps, and 3D features may not work until it is enabled.
