It's very easy to install Chrome on a linux box and launch it with a whitelisted extension. You can run Xorg using the dummy driver and get a full Chrome instance (i.e. not headless). You can even enable the DevTools API programmatically. I don't see how this would be detectable, and probably a lot safer than downloading a random browser package from an unknown developer.
Hmm maybe I will if I have time. We've been using this technique for user-initiated scraping. The only issue we've run in to is we get rate-limited by IP sometimes. Changing the IP has solved the problem each time.
If I am correct in assuming the parent is talking about puppeteer, there is a plugin[1] that claims to evade most of the methods used to detect headless browsers. I have used it recently for just that purpose, and I can say that it worked wifh minimal setup and configuration for my usecase, but I guess depending on the detection mechanisms youre evading YMMV.
The creator of that plugin does mention it is very much a cat and mouse game, just like most of the “scraping industry”
