GlassBox - What your browser reveals to every site you visit
Show HN: GlassBox – what the browser reveals, and how identifiable you are
GlassBox is a diagnostic mirror that runs 31 fingerprinting and device-enumeration techniques to show you exactly what your browser exposes to websites. It rates each signal's identifying power, from high-signal canvas and WebGL fingerprints to medium and low signals like timezone, fonts, and network info. The tool computes an identifiability percentage based on published entropy, helping you understand how uniquely trackable you are. It also simulates third-party tracking pixels to reveal what Facebook and Google Analytics see. Perfect for privacy-conscious users, developers, and researchers, GlassBox is a companion to CodeCanary and is open-source on GitHub.
Individually, most signals are weak; combined, they routinely single out one browser in millions. That combination is the whole game.

The solution for me is not to be more common. The solution is to create a very unique profile each and every time.

Pretty sure someone else also promoted Claude to make something like this and posted it a few weeks back.

> 1 in 7.6 billion browsers share this profile
I always knew I was so unique

This doesn’t seem right. 1 in 6.2 billion for Firefox on an iphone, not including ip/network uniqueness?
Seems more plausible that anti-fingerprinting is throwing it off?
