Well, to be fair, I do have an experience working on a Windows Forms app from scratch. App connects to a very specific scanner via customs drivers and makes use of a remote API for data tasks. The app works, it's stable, but I'm not going to lie, AI assisted coding for this particular stack does require a very large amount of nurturing, it is just not the same experience you get with web apps. Nevertheless, it did it.
I took a few shots at building desktop apps with Tauri, Wails and Electron using Claude Code, and the results were not very good at all. In fact, they were by far the worst results I've gotten with the tool. I can easily clone one of my boilerplate repos in Rails, or Django and prompt away, and the results are consistently good, as in, functional MVP in a few hours. This was never the case for the desktop tools I mentioned.
This looks like a highly specialized tool for desktop that actually works. I watch the demo and I am assuming the apps are actually made with some kind of technology a la Tauri, or Electron, thus making the apps cross-platform.
I don't think we are anywhere near a tool like this for native, but that's a lost battle anyway.
