Piped
Piped is an alternative YouTube-Frontend. It establishes only the most necessary connections to YouTube and many of them are even made by the server itself. So Piped increases the privacy of the users.
From December 2019 to September 2022, I ran a public Invidious instance. This was replaced by Piped as of October 2022. Feel free to watch some videos there.
