I am very interested in this. I am a low-coder you could say. I have to start coding a front-end in React soon (and I have yet to learn React) so with all the overhead of learning React as well as fiddling with html, css etc, it feels like a really big task. I saw some visual builders for React , downloaded/tried a couple but they had pretty big learning curves of their own so I didn't bother taking it any further.
You guys seem to be addressing the right pain point in the right way.
I will definitely give this a go soon
