Only other option would be a domain name and a reverse proxy.

This is how I set it up for my family and friends. Works like a charm, especially if you have a dynamic IP. Everyone just signs in through whichever app they want to use.

Futo is open source. It’s not FOSS though.

I used AnySoft Keyboard until someone recommended Futo here on Lemmy.

It’s ridiculously good, even with languages other than English. It will nail German 20-character compound words first try and I haven’t seen any other keyboard do it this well.
