The main problem with these kind of tools is that they sit in a "dead zone" of being too in depth for non-technicals, yet too limiting and inefficient for engineers to bother with, as they end up injecting a huge bundle on the page just to render a form. How are you solving for that?
I think this is a great example of why we need more product people involved with FOSS. Having worked in dev for quite some time before I got into design, I’ve experienced the blind spots inherent to having a purely technical focus. From the dev perspective, user needs often seem straightforward or even intuitive, but that’s heavily skewed by a completely different approach to using and reasoning about software than end users have. Developers are often pessimistic about users that seemingly always fail to grasp something they consider trivial, but developers rarely have to confront the actual complexity of other people’s jobs. Lots of people are smart and can solve problems, even if they don't have a formidable mental model of software development. Tweaking basic HTML/CSS generated by something else is well within their problem-solving capability and doesn’t require much technical know-how.
