Fingerprint

How unique is your browser?

We calculate canvas, WebGL, audio, font, and feature fingerprints — entirely in your browser. Each one is a slice of your unique configuration. Together, they often add up to a near-unique identifier.

Nothing is sent back. All fingerprint values are computed locally in your browser. Open DevTools → Network and reload to verify — you'll only see the standard page + analytics beacon.

Want to stop being uniquely identifiable? Tor Browser is the only mainstream browser that actively tries to make all users look identical. Brave and LibreWolf randomize/block individual fingerprint vectors but don't fully unify. See our recommended browsers.
