Freetube is nice alternative to using youtube without an account, since things like subscriptions, playlists, history are saved locally without an account. And you can back up that data.

And with Google being behind youtube its better to avoid signing into their accounts anyways.

Also blocks ads, can download videos, sponsor block, dearrow, and block channels.

Sometimes freetube breaks and that’s when I’ll fall back to youtube with adblock om browser, but I won’t log into youtube. But, you can still use it to get your subscription feed and click on the video to launch to browser.

For mobile I use pipepipe which is a fork of newpipe with sponsorblock and channel blocking.
