Rehike. It’s meant to be a re implementation of the older hitchhiker youtube layout that youtube had back between around 2015-2020. It doesn’t do anything for privacy but that’s not the point of it so I don’t mind. I’ve tried things like newpipe and invidious but youtube is around 90 percent of my media consumption so having my history, likes, playlists, and recommendations synced between all my devices is too much for me to give up.
