Fascinating technology - it's good to see good ol' Swing and Graphics2D being used to target browsers in the same way React Native has gone the other way and allowed swapping the DOM renderer for a native renderer. I have a couple of questions, though. What is the pricing strategy? (Programmers who'd use it will grumble that its not FOSS, then those same programmers will grumble when the maintainers quit maintaining it. I suggest ignoring the grumbling entirely.) It's also a bit awkward in that my sense is that most (enterprise) UI programming is done with web tech, and has been for at least 10 years. Where are these Swing programmers going to come from?!
