Discover Your Browser's Unique Fingerprint
A scientific browser fingerprinting tool with real entropy-bits scoring (not just a vague "rating"), live cohort comparison against today's visitors, defense-test mode that detects whether your anti-fingerprint extensions are actually working, and a unique visual fingerprint art generated from your hash. Free, instant.
How to test your browser fingerprint
The tool scans 8 vectors in your browser: Canvas, WebGL, Audio, Fonts, Hardware, Math, Timezone, and Features. Each is hashed with SHA-256.
Total bits of entropy is the scientific measure: under 8 bits = grade A (hard to track), 26+ bits = grade F (uniquely identifiable).
See live how many of today's visitors share your exact fingerprint. "1 of N" means you stand alone among today's scans.
If you have CanvasBlocker, Brave Shields, Firefox RFP, or Tor — click "Test my defenses" and we run scans twice to detect whether protection is actually randomizing output.
Save the current fingerprint locally; return later to see which vectors drifted. Fingerprints are not actually static — installing a font, updating a driver, even changing screen resolution moves the hash.
