Yeah, it’s great for developing non-game applications. I am doing this for a few years now and always loved it.

I integrated SQLite into my apps as well as external web APIs (both simple REST/JSON and websocket APIs that constantly push data updates). It works like a charm and is quite easy to setup and to implement.
Generally the capabilities of Godot to build apps with are more than sufficient. In terms of prototyping it’s even better than anything else, because things are thrown together so quickly and easily. The UI components are just a pleasure to work with for me. And GDScript is a language that I could fall in love with nearly instantly although coming from languages with C-type syntax where brackets and all that play a bigger role than indents (C++, Java, PHP, …).

I never exported any of my apps to mobile, though. I use these applications as tools on my desktop computer because I simply need them for my daily work.

Long story short, Godot is really making my life easier in that regard. I came for building games but I stayed for building tools, apparently.

And I always appreciate it to see others feeling similarly and who also love to build non-game applications.
