The author seems to be making use of: fpscanner[1] and fp-collect[2] libraries for achieving his task though he doesn't seem to explain how exactly the detection is done. [1]: https://github.com/antoinevastel/fpscanner [2]: https://github.com/antoinevastel/fp-collect

On his actual "test" page, he claims he is not using fpscanner: https://arh.antoinevastel.com/bots/areyouheadless

That's from the linked test page https://arh.antoinevastel.com/bots/areyouheadless

This would be more interesting if the author explained this technique. People that are knowledgeable enough will deep dive into the webpage, but for everyone else, expect disappointment.

I'm not sure if diving deep into the page will yield results of how it's done. The page's javascript does a POST to a backend with the browser's fingerprint, and the server does all the "magic" where we can't see it. Unless there is new fingerprint info that is being sent to the server that wasn't around before, I'm skeptical about the javascript in the page revealing the full technique.
