Prefacing this with the fact I don't know all that much about the product, only a quick glance
For a big team of developers, building a big website with complicated interactions or requirements, a tool like this isn't going to meet all the requirements the developers have
If you're building something simpler, then you're probably better served by something like Webflow or Squarespace.
In my head, I'm wondering if they are just way too early? Going from design -> code -> UI is, in theory, less efficient than just going from design -> UI, in a programmable, customizable, scalable way.
I'm super curious around what the sales strategy was.
I'd imagine for devs, it would have to be around productivity (time saved by exporting vs. manually coding, adherence to consistent CSS standards, etc.).
For designers, I would imagine it would be around taking more of the software dev lifecycle - e.g. designers can now eat up part of the value that front-end dev provides. Based on that, designers should be more in demand, paid more, and so on.
Those seem like huge levers to pull from a PMF perspective, but to your point, maybe it all sounds great until you get into that conversation, and it's really not something that teams are looking for (at least right now).
Loved Delphi, Forms, Blend, Netbeans Matisse and JSF designer, Blend, Outsystems, ...
As mentioned in another thread, these kind of tools with good workflows and developer experience don't get written for free.
making stuff is never going to go mainstream when you can just pay someone to do it for you
