For example I saw a post asking for recommendation for a "self hosted budget management app"

that's not something I would host on my home server, but that doesn't mean it doesn't have an audience.

not everything might be for you!

perfect timing, i just got laid off a couple weeks ago lol

i made up a not real, non-standard TLD that i use lol (.null)

I have a self signed CA that all my devices trust. Getting a real domain and just using that, with LetsEncrypt, would not have required me to explicitly trust my own CA, but hey, my system works.

and i know i know, RFCs, but it works, and doesn't break anything.
