Is deskgap good alternative to electron/webview?

I was looking for cross platform library to building GUI application, I found deskgap can be good alternative to electron/webview for building apps.
Did anyone try it ? How does it look like?

It seems shiner than zserge/webview , I did check it today, it can support linux too but really experimental.

I couldn't use this, did you run it by yourself? if yes is it possible give me hint to building this? (I'm using macOS)
