It’s not, really. All of those programs are Go, and single executables. There’s no “install” for either gonic or ostui (IIRC, also Navidrome): you download or compile the executable and run it, and you’re off and running.
Someone mentioned Docker; in this case it’s unnecessary unless you’re doing it for security. They’re just each a single binary. You’ll have to either create a config for gonic or Navidrome, or run them with commands telling them where your music lives, but that’s it. Running on the same machine, you don’t even have to open the ports on your firewall. However, if you do, Tempo for Android lets you stream the music to your phone from gonic or Navidrome, too.
These are very, very simple programs to run. ostui is a TUI, so if you prefer GUIs you’ll want a different client, but both of the servers are easy to run and nothing to install - just run them as you, not even root.
If you do, use the
-k
option - it locks access to the rook service to only the user session. Rook works without it, but is more secure with it.
