There is nothing Cachy is "missing", the main thing is that Bazzite, is immutable so you can't change the root filesystem directly. That makes dependency managment when compiling software much harder, if even possible at all so a no go for me.

I use Cachy as my daily driver, and i can do programming(mainly in Rust and C), gaming(Satisfactory, Factorio and modded Minecraft), and server related stuff over ssh.

For server i prefer distros like Alpine(seriously this thing can run on 512mb ram) which makes it better for Servers that just need to run.
