I don't remember for sure. It is it's own open source project however. I do use lutris as well, but mostly for emulators. > Personally I had better luck fiddling with Wine than with Proton.

Almost all of my Window's only games I have in my steam library and I've just been able to click install and play, so I haven't looked in depth at any of the other options yet.
