The sheet looks really useful, thank you for sharing it. I did the same research and ended up with the same conclusion which is why I went with hostingby.design, but after interacting with the people on discord it looks like the main guy is swamped with work and unable to really make new scripts and stuff.
Ultra.cc looks to have better app support and they aren’t using swizzin as their backend but app-box or something like that.
I tried distrobox without root which doesn’t work I also tried user install using apt, but unless the whole program is a single compiled binary, it isn’t working very well.
My other complaint is that I don’t know how their reverse proxy and wildcard certs work, so I can’t even put all these unofficial things (prowlarr, overseer) behind https.
