It’s this one: https://git.gammaspectra.live/git/go-away
the project name is a bit unfortunate to show for users, maybe change that if you will use it.
some known privacy services use it too, including the invidious at nadeko.net, so you can check there how it works. It’s one of the most popular inv servers so I guess it cannot be bad, and they use multiple kinds of checks for each visitor



ps: I was wrong it’s not a fork, but a different thing doing the same and more
