Maker here. GlassBox runs 30+ live fingerprinting checks against your browser and scores how identifiable the result makes you, measured against the ~33 bits of information it takes to single out one person on Earth. Everything runs locally in your tab, nothing is sent anywhere.
Glassbox shows you exactly what your browser hands to every site you visit: canvas and WebGL fingerprints, fonts, timezone, hardware signals, WebRTC IP leaks, and the trackable combination they form. Everything runs in your browser. Nothing is uploaded, stored, or sent anywhere. Built by a security engineer who wanted to see his own fingerprint the way trackers see it, then fix it. Open source, no account, no backend. Open the box, see what's leaking, close the gaps.
