Yes, it’s a paid service. It’s about 3 or 4 euro per month. I tried it once because I was annoyed by the lack of seeders and buffering in stremio and I’ve never looked back since. It requires a bit of setup, but when that’s done you’re good to go.

I pay for YouTube premium but still use Revanced since the regular app sucks.

Jup, debrid is the way to go.

I always use Stacher. You can find it on Stacher.io

I use https://stacher.io/. It’s a yt dl UI.

Absolutely love it. Very easy to use and lots of options.
