I’m self-hosting Piped and couldn’t be happier. Clean, distraction free and, importantly, private. No data mining. Importing your subscriptions from a Google Takeout dump is simple.
LibreTube for Android is my mobile client, and talks to my Piped server without any issues. The only thing missing at this stage is a client for my Chromecast GTVs. For those, I still watch YouTube with SmartTubeNext, which means keeping two sets of subscriptions in sync. A little frustrating, but relatively painless, for the privacy benefits.
