apparently there are not many good alternatives.I obviously have tried few popular that come up when you search for "open-source android keyboards" but asking here just in case I missed some.<p>No swipe typing is a deal breaker for me. I am very much used to Gboard swipe
I use the play store version of Simple Keyboard <a href="https://github.com/rkkr/simple-keyboard" rel="nofollow">https://github.com/rkkr/simple-keyboard</a>. It doesn't have swype, but for what it does have, it consistently just works; and it only has the vibrate permission, so it can't do very much (not even use the internet, which doesn't need a prompt, but does need a permission in the manifest)
I use OpenBoard, installed from F-Droid. It's lightweight and doesn't leak your data.<p><a href="https://f-droid.org/en/packages/org.dslul.openboard.inputmethod.latin/" rel="nofollow">https://f-droid.org/en/packages/org.dslul.openboard.inputmet...</a><p>Unfortunately, it doesn't have swipe but I decided to prefere a data protection friendly tool. I'm not sure if you can have both at the same time.
I've been using OpenBoard after learning about it here on HN:<p><a href="https://news.ycombinator.com/item?id=25669538" rel="nofollow">https://news.ycombinator.com/item?id=25669538</a>
