Since we're on Lemmy, which uses ActivityPub, I'd first recommend using PeerTube since it's also a fediverse ActivityPub platform. But it's pretty small right now.

Alternatively, Odysee has an established creator base and it's easy for YouTubers to sync video uploads, so it has a real chance at becoming mainstream if we can push adoption outside of the tech-sphere.

In terms of just YouTube privacy-respecting frontends, with your browser I recommend using Piped or Invidious.

For more instances for privacy-respecting front-ends, this link is a good resource. Furthermore, you could consider installing the LibRedirect extension to automatically redirect you to privacy-respecting frontends.

On Android, I strongly recommend downloading LibreTube or NewPipe from the F-Droid store. LibreTube is actually really pretty, so I prefer it to ReVanced on that basis as it doesn't require any level of login to manage a subscription list I think. Newpipe is already very well established and I use it personally, very good app.

Happy to answer any questions, but I'm not an engineer, I'm just a guy :p
