Show HN: GlassBox – what the browser reveals, and how identifiable you are

GlassBox is a browser tool that measures your digital fingerprint across four tiers—from hardware/environment factors to session-specific data—to show how identifiable you are and how trackers might link you across browsers. The tool runs locally in your browser (except for optional IP geolocation lookups) and allows users to compare fingerprints across different sessions to understand cross-browser tracking techniques. It provides guidance on reducing your fingerprint and demonstrates the methods real trackers use to identify users.
