Kivy in beta stage - I'm not sure how to answer that question. Kivy is at 1.9 at the moment. That said, I believe the changes are fast and quick. Meaning - keeping up is an issue. Mostly, they are adding features like more sound and video. But as far as I'm concerned they haven't broken anything for a very long time. The biggest issue with kivy has been the build process. But the programming has been easy and slick.

As far as Dabo there are three versions - the stable version that works with wxPython 2.8.x but not with python 3 , what I call Dabo 2 that works with wxPython 3.x and python 2.7.x, and Dabo 3 which works with wxPython Phoenix and python 3. Dabo 3 lacks a complete working grid control that matches how Dabo works with grids. But most other controls work just fine. Everything works with Dabo 2 and Dabo stable but only with python 2.7.x. All three are cross platform.

That's the current state of the two!

What we do:

We still have users that are using desktops (and in fact do not want browser solutions) and they are using Dabo. As you know Dabo provides a very easy way to provide CRUD apps. And it covers all the desktops without any question (including windows 10). But we soon needed a mobile app and we turned to Kivy. The reason we did so was that we could re-use the much of the Dabo business rules and code. We created an off line sales ordering app, a warehouse scanner app, and a management dash board all using Kivy. We are also using Kivy on the desktop now. Kivy is cross plateform and that includes mobile. Dabo is easier than Kivy for CRUD apps but in other ways Kivy has some advantages - like declaring the UX/GUI. The UX/GUI is not fixed with Kivy like it is with Dabo.

As far as Dabo and the web - you realize that at least five years ago Dabo had a web solution. That said, I've not used it. So I don't know much about it. Ed Leaf demo'd it at one of the Python conferences. I saw it working and at time had little use for it.

Now that said - I would still recommend that you learn javascript, css, html and the rest of the web stuff. When we need a web solution we turn to Django. Although Django is python it still requires some javascript etc...

Hope that helps.
