Yeah, getting a webapp up and running for small amount of users is tedious. Either complicated install or permanent hosting cost and permanent cost for keeping maintained. A desktop tool has a lot less security vectors as it's all local.

Of course there is electron, but that has its own set of complications.

For simple tools RAD is great.

Since Firemonkey draws on Skia anyway, they could also provide something similar to Flutter/WASM.

I love the Flutter/WASM idea, but cannot get warm with the widget in widget approach flutter uses. Having a designtool like Delphi's would be nice.
