Torrents?

Jellyfin is also useful for music collection. I tried both it and Navidrome to start with, and ended up only using Jellyfin.

There are some periods where YouTube make changes frequently so that e.g. FreeTube stops working for some time, but for the most part it works reliably well. I would say it provides a much better convenience than watching on youtube.com logged out, as you have profiles, subscriptions, playlist and history. Including adblock, sponsorblock and dearrow, and granular control over what to show or not (comments, shorts, live etc.).
