It started as a paid app closed source, it is now a paid app open source. kindaVim brings Vim motions to the whole macOS, in texts and in UI. It costs a coffee a month or else the app “falls asleep” sometimes. Or you can just compile it from scratch and you’re good to go.

Available on https://kindavim.app.

The source is as usual on GitHub: https://github.com/godbout/kindaVim.theapp.
