@seeker I think there are firmly held opinions about this, but hosting at home is more properly called homelabbing, or, running a homelab. I think there is a big enough difference in what you need to keep in mind between running a server (whatever shape or form) at home vs running apps and services on a VPS or bare metal server, not the least of which is going to be network access and security.
That article does make a nice point distinguishing "self-host" OSes from dashboard/docker management systems.
I think voting for apps is based more on the fact that enough people have been paying for a commercial version of an app and know about and want to move to an open source alternative. I don't think anyone here is voting for apps they have no familiarity with. That said, seeing what gets suggested has sometimes led me to see which other platforms might already have it (I'm using affine on my runtipi VPS, for example) and I see what the fuss is about there. My curiosity has led me to install runtipi on my Dedirock VPS where I have affine, Obsidian LiveSync, GrampsWeb, FlightLog, and Write-freely. I'd switch them all to Cloudron if these were available here. I've tried almost all the alternatives, and I've stuck with runtipi the longest (despite the stupid name). The rest just always, and I mean ALWAYS, crap out eventually and either the forums or help have been very very weak, or actually non-existent (no one knows what went wrong and how to fix it). Forget them!
