Are there any widget sets for native-like programming inside a browser?

I was pretty excited to see this article today:

It’s got me wondering: Are there any widget sets usable from Python in Web Assembly yet? How mature are they?

I’ve been on the fence about jumping to Rust or C++ to use EGui or ImGui, but I’m not sure I really want to abandon my history with Python.

What I definitely don’t want to do, though, is to get stuck using the DOM from JavaScript and TypeScript.


I developed LTK and made it open source, see github.
I am actively using LTK to develop PySheets.

LTK is elegant, easy to use and enhance, and quite stable now. Try it out.

You can run many Panel widgets on top of PyScript/Pyodide.

You might also look at starfyre,a reactive frontend framework built by @sansyrox on top of PyScript.

Are there no Immediate Mode or Retained Mode GUI toolkits for Python+WASM? That’s really what I’m hoping for.

I actually am kinda hoping WASM is going to make all this Reactive stuff go away. It’ll be hard to stop JavaScript/TypeScript/HTML/CSS/DOM/Components’ inertia completely, but I see them as a bit of a mess that was temporarily necessary in the history of computing.
