No TeaVM doesn't do Swing or JavaFX. But WebFX does: https://webfx.dev/

Gluon also has a cool JavaFX in the browser demo but I think it's dead: https://gluonhq.com/developer-preview-for-javafx-inside-a-we...

This performs very poorly on whatever machine I use! https://raytracer.webfx.dev

Webfx looks like something I could use, thanks!

You could also check out https://jpro.one which is a commercial solution but very impressive - and because rendering is server side, very fast as long as you're in the same continent as the server. The website is itself served by JPro.

Of course you could also just distribute such apps as desktop apps... I will happily sell you a product that makes doing that easy :) https://hydraulic.dev/
