But also I think that's kinda the point. Like for example we have to do a UI redesign of an app my company is building and our "wireframes" are just v0 projects my PO created in one afternoon.
I think wireframing is where these tools really shine. It's gives you roughly the same ideas as building a wireframe in Figma but it's way less work and you end up with higher fidelity wireframes.Like sure if I were to peek at the code under the hood I'm certain it's close to dogshit but the code doesn't really matter at that stage.
Either way, my point is the customer LTV will be super low for use cases like this.
I'm sure there's already integrations somewhere that could allow a designer to specify a bunch of brand colours, to generate a styleguide out of it in plain english, and get a working prototype out of it.
Following a styleguide will make your software break as soon as the design system gets updated.
Behaviors will be whatever component library they're using does.
