I know this isn’t a self hostable app and just a alternative client that pulls music from youtube and uses song recommendations from spotify, but I switched to Spotube. It has some bugs, but hey it’s written in flutter and I know flutter so I’m able to contribute.
Its less of a need for powerful hardware and more of a want.
I started off my days with a laptop that had a broken screen. I took screen off and hid it behind my desk, worked perfectly fine, even came with a built in backup battery too xD
