I think you can search for discord servers in the web/desktop app, can’t you? I’m on mobile at the moment and don’t see it in the app. I feel like I’ve done it before though.
Ordinarily I look for something more specific about what I’m trying to do… For self hosting stuff, the kubernetes@home thing is solid. The cncf server is great too. If that’s not you jam though obviously it won’t help… For me personally, kubernetes is basically just a modern implementation of a Linux distro. Obv ymmv.
