I’ve looked at a few on fdroid and they all seem like they aren’t being maintained anymore.
Edit: I’ve spent the past day trying most all of the suggested keyboards here and I think I’ve landed on either Unexpected Keyboard or AnySoftKeyboard. Thanks for all the suggestions. Thumbkey is quite the thing to get used to.
I tried most of them, it’s just not the same as Gboard.
Anyone know if you can block Gboard with DNS?
Idk but you could always just install gboard & not give network permissions. You’ll lose a little functionality like the ability to add gifs from the keyboard which obviously need internet to search/load.
