I've always had a fascination with reverse-engineering browser fingerprinting scripts. Most of my time has been spent looking at the usual suspects (popular fingerprinting libraries like FingerprintJS and more sophisticated scripts used by anti-bots like Cloudflare Turnstile, Akamai, and others). At some point, I wanted to know what else was out there. I had an idea: What if I crawled the web and intercepted fingerprinting-related browser API calls and mapped it all?
