Do you have any tips (or examples) using quadlets? I tried using them but I couldn’t wrap my head around them.

I’ve heard good things about Instander, but it may not satisfy all the requirements of an alternative frontend.

+1 for quadlet. It’s another file format to learn, but it’s worth it, particularly if you want your containers to auto-update. Also check out podlet to help mitigate some of the compose to .container issues.

LibreTube suddenly was really laggy on all instances, but the instances on browser are fine. I’m using NewPipe/Clipious for the time being.
