I have looked around the website and I really have no idea what this is. I feel their marketing and doc could do with a bit more explanation if it's intended for devs. Is it like applets in that there is a runtime in the browser? Or more like GWT which compiles Java to Javascript?

Also, the website which is apparently created with the technology, is incredibly slow, at least for me.

And the website doesn't give useful loading indicators, e.g. click a link, nothing happens, or go to the doc section and navigate and lots of empty screens (presumably while the content is loading). No browser loading indicator, nor spinner in the content.

Judging from the browser developer tools, something that (very slowly) sends the client stuff via a socket.

Interesting. Runs app on the server, does final rendering of the UI's scene graph on the client (within the browser).

It's not clear from skim reading if the client side rendering is implemented with the DOM or a canvas element.

I've always thought it'd be hysterical to use canvas. The whole browser just to hoist a client side frame buffer. X-Windows reinvented.

FWIW, JavaFX is so close to The Correct Answer™. Definitely the best effort thus far. (I haven't used SwiftUI yet.)

The calendar demo I tried was quite slow as well.

there's a price for this??

I'm not sure what this is by looking at their homepage, is this similar to WASM?

also who would pay to develop something for the web anymore?

I made an applet in ‘99. As good as a React app these days.

Looks like it’s a custom webserver.

Site appears to be down, there is an archive here from June 2020:

Newer archive on IA from March this year doesn't load anything:

However has source code including:

So assuming there was a newer site that had some sort of embedded Java thing...

By the sounds of it, it was a demo where the website ran as java on the server, rendering and pushing to the browser in real time? Guessing it couldn't handle HN traffic...
