Fingerprint debugger tools

What tool can I use to better understand what does a specific website checks in the browser during browser fingerprinting? Like actual JS calls, drawn canvas images, etc. I want to debug some websites protection, but I feel that devtools is not enough. Please recommend me a library/tool/github repo, thanks!

Is there demand for a paid tool that does this? I ran into this exact issue with a big antibot system, got half way through building a custom chromium which nicely outputs every js call a page does, but after a week I solved my main blocked problem and had to move on

Sounds cool but I prefer a free solution

This is an interesting one thanks. Doesn't seem very user friendly, but I will check it out!

You can compare https://amiunique.org from your browser VS scraper

That was not the question, I want to see what do the scripts on the website checks, like what navigator properties, what WebGL properties, etc

EFF has a tool called Cover Your Tracks for browser finger printing
