Out of all the apps you've worked on, what's one or two that you think came out really well?
Honestly, I have so many features in it now it's hard to describe it, shared work calendar, parts shopping list, recurring maintenance, blah blah blah. It's very bespoke and I doubt anyone else would want to use it the way we do.
In my case I just don't expose them to network at all, any interaction happens through bots in IM or on a tablet at home (through wireguard).
Theoretically locking it down with OAuth on proxy level would also work, but I prefer to keep it off the internet (apart from the tunnel, obviously).
