I was wonder why aren’t devs making desktop apps any more, especially since everyone is buying laptops and desktops again? With all the tooling out there for cross platform, a native experience, and better privacy/security than a webapp.
For example, Here are just two frameworks/tool kits that are easy to use and to build desktop apps with.
React Native for Windows and MacOS: https://microsoft.github.io/react-native-windows/
Avalonia UI: http://avaloniaui.net/
Also, If they do use frameworks like the ones mentioned above they will still only release the app for mobile and then rebuild the code for a webapp which is slower and does not have the functionality.
