It may be a very niche space, but sometimes you might want to build a desktop app. Of course native apps always allows the best compatibility, for example swift for mac/ios and I presume win32 or .net for windows.
However, sometimes you want to use a language that can build for everything.
This is where technologies like Electron, Tauri, flutter come into play. But one technology, often goes under the radar.
Actually, I think this technology is really good. And that technology is QT. The reason why I think it is good is because, the widgets look native by design, and performance is great being written in c++. QT is one of the few technologies that also supports embedded systems.
I read somewhere that the interface Tesla uses for their cars is based on QT and it looks beautiful and is also buttery smooth. If I were to build a desktop app, I would most certainly consider QT as a primary contender. And even taking it one step further, when it comes to simplicity is pyQT, which allows you to use python - this too, seems a great idea.
I don't have the time to explore this, nor do I have an app idea that would benefit from being a desktop application. But yeah, I really like QT.
