Browser Check
What your browser reports about itself, your display, and its graphics capabilities. Every value on this page is read locally and never uploaded.

How this works
Each value is read directly from browser APIs in your browser. Graphics checks create a throwaway canvas and read its context. Nothing is sent to the server.
Input
- No input required
Output
- Browser name, version and rendering engine
- Operating system and platform
- Screen size, viewport size and device pixel ratio
- Language, timezone and touch support
- WebGL and WebGPU availability and details
- Automation indicators
Privacy
Everything on this page is computed locally and never uploaded. The page does not ask for camera or microphone access and does not enumerate your media devices.
Limitations
- The user agent is what the browser claims, and can be changed by the browser or an extension.
- WebGL and WebGPU being unavailable is a capability limit, not a fault.
- Automation indicators are observations; a positive result does not mean an account would be blocked.
- Screen size describes the display, not the window, unless the viewport value is read.
Frequently asked questions
What browser am I using?
This page reports the browser name, version and rendering engine as your browser describes them, using the user agent string and, where available, the structured userAgentData API.
Why is WebGL or WebGPU unavailable?
Hardware acceleration may be disabled, the GPU may be blocklisted, or the browser may not implement the API. Unavailable is reported separately from failed.
Does this page identify me?
It reports environment values that a website can read. It does not compute or send an identifier, and there is a separate page that explains fingerprinting in more detail.
