I've been using Baïkal for about a decade. I have it in a docker container on my home lan. Android and iOS transparently and gracefully tolerate the server being unreachable outside the house.
The main issue is that I only touch it every five years or so, and at that point, I've forgotten what it is called or where it is running!
(I use synology's HyperBackup to E2E encrypt + backup it and a bunch of other docker containers.)
