I am looking for a good FOSS keyboard with suggestions and the ability to add multiple languages.
I use OpenBoard most of the time and it’s good if you are more privacy focused.
Is it possible with this keyboard to swipe instead of type?
No, it’s not possible by now
If you install a fork of it with that feature, yes. I personally use this fork: https://github.com/erkserkserks/openboard
Haven’t seen unexpected keyboard mentioned. Been using that for a few months now. Lots of keys, not many other features. With a compose key, it would almost be perfect. Hackers is my backup keyboard.
I use AnySoft Keyboard. It is very configurable and has a lot of language options.
I use FlorisBoard
I was following this for a while but see it hasn’t received an update in a year now, is it abandoned?
Vanilla GrapheneOS keyboard as per their guide.
