OpenUI: Open Standard for Generative UI

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.

Rendered div soup with pictures of data isn't a web standard and shouldn't be professing to be built for a11y.

Don't advertise "cross-platform" and list React, React Native and Vue as your platforms. The world is not JavaScript, at least not yet.

Where do you see "cross-platform"? The readme clearly says it's web:

  OpenUI is a full-stack Generative UI framework: a compact streaming-first language, a React runtime with built-in component libraries [...]

The link submitted is to the front page of their website, which reads: “Cross-platform - One spec renders natively to React, React Native, Vue, and more.”

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, joel@joelparkerhenderson.com.

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.

Sure the term has been enshittified - but this is MIT licensed. I think that helps rebuild the integrity of the phrase "Open Source".

It’s unfortunate that this name was used. There is a W3C community group called OpenUI (https://open-ui.org/) which has been around for close to a decade, working on improving UI standards for the web.

Sounds like something you come up with when you think of a cool name first and then just make something that fits the name.
