GoKawiilGlassBox tool exposes what browsers leak to trackers and fraud scripts
A developer released GlassBox, a Show HN project that runs live in a browser to capture the same fingerprinting signals used by tracking and anti-fraud scripts, then displays them to the user instead of hiding them. Users can also paste a JSON report from another browser or session to compare fingerprints, and GlassBox scores similarity to indicate whether the two reports likely come from the same machine, engine family, or browser.
