Browser Info, Fingerprint & WebGL
See what any website can read about your browser and device. Details, fingerprint and WebGL in one page, all measured locally.
Three views of one browser
Overview lists the browser, system, screen, hardware, language and privacy settings plus supported features and codecs. Fingerprint builds the identifier that sites can compute from canvas, audio, fonts and layout. WebGL shows your GPU, its limits and extensions.
Nothing leaves your browser
The scan runs locally. Only the headers of your own request are shown from our server, so you can compare them. You can copy or download the report as JSON, for example for a bug report.
Stable or randomised
Every fingerprint signal is marked as stable or randomised, and the result is compared with your previous scan on this device. A fingerprint that stays the same between visits lets sites recognise you without cookies; one that changes each time is far harder to follow. The tips under the report show how to blend in.
Frequently asked questions
Does this page send my data anywhere?
No. Everything is collected in your browser and shown only to you.
What is a browser fingerprint?
A combination of small differences in your browser and device that can identify you without cookies. A stable fingerprint makes you easy to recognise; a randomised one is harder to track.
How can I reveal less?
Use Firefox or Brave with fingerprinting protection, or Tor Browser, and avoid unusual extensions or settings that make your browser unique.
Why does the page say Windows 10 on Windows 11?
Browsers freeze part of the user agent for privacy. The real version is only available through Client Hints.
