Sounds like something you come up with when you think of a cool name first and then just make something that fits the name.
I hate the naming. "Open" is so abused by now that I start to distrust software that needs to explicitly state that they are "Open" because they usually aren't.
Don't advertise "cross-platform" and list React, React Native and Vue as your platforms. The world is not JavaScript, at least not yet.
If you want more open UI, I lead Lily Design System (https://lilydesignsystem.github.io) which has hundreds of components for Svelte, React, Vue, Blazor, Nunjuks, and HTML. The focus on semantics helps AI generators, and there are many prebuilt themes, locales, and examples. I'm using Fable right now to improve it.
If anyone from OpenUI would like to connect with me to add Lily, please do, [email protected].
Looks like a DSL for UI. Interesting.
I entered "CRUD for public book library" in their playground (https://www.openui.com/playground) and it generated some forms which looks useful:

I'd have to investigate more about the customizability of it. For example, how hard is it to implement custom form validations? This sort of thing.
Also, how many dependencies and layers I would be adding to my project for using it.
