NewPipe is good for privately watching YouTube without ads and other premium features like picture-in-picture, listening in background and downloading the videos for offline view. https://newpipe.net/

Like Alex said NewPipe is one there's also libre tube

https://libretube.dev/ and https://invidious.io/

Rumble, Bitchute

Hm, pip and dowloading without using tubemate is a plus compared to the brave browser.

Hm, I would zap you, but it fails again.

😐

Invidious - still youtube but without the crap. Use with a vpn for better anon set.
