Libretube with my own Piped instance, almost flamless. One line setup with docker, Runs perfectly on a 5$ VPS. I haven’t entered youtube in months, there is no reason other that to import suscriptions, channels, etc.
Only problem is for some reason some not-so-popular videos are slow to load on 720p, but load fine in 480p or 1080p. Really weird.
A year ago that would randomly appear for me. It seems they were a/b testing it.
