Glassbox runs entirely in the browser, exposing raw fingerprinting data without transmitting it externally.
The tool incorporates recent techniques like silent audio waves, used by sites such as AliExpress, alongside traditional methods like canvas and WebGL fingerprinting.
Identifiability estimates vary widely, with Tor Browser offering the lowest uniqueness risk and mainstream browsers like Chrome often rendering users effectively unique.
