The amount of gatekeeping I’m seeing here is insane

I tried both and for some reason Baikal just played nicer. I’m sure either is fine though.

Nextcloud was too bulky for my needs.

You could try Withings. I believe they’re based out of France.

As others are saying, OSMC might work. Most difficult part is making it so that the TV turns on when you turn on the computer since ARC isn’t a thing for most computers.

I ended up giving up on OSMC and bought an Apple TV since nothing else got the “wife approval” factor. It’s better than Google getting my data, has a Plex client, and let’s me stream my Steam library.
