Introducing the UI SDK.

I'm not sure I quite understand the appeal given agents can create functional ui perfectly well as it is. It's the aesthetic and design they struggle with, not behaviour

Will UI SDK exist alongside Base UI, React Aria, Radix UI as a new UI primitive option?

how it differs from pointing an agent to shadcn?

so good

I tried looking at the repo a bit but I’m not sure I quite understand the value prop of this versus something like Base UI. Is the thought process that we should be thinking about UIs/components as combinations of behaviours?

Behaviors? 🧐

is this a product release or a rave party? - yes

@shadcn One of my colleagues sent this to me😅

wild soundtrack

that's @zag_js , I hope it's at least as good with nice observable state-machines and work on any ui-frameworks with adapters (otherwise it's cringe imo)

I called it.

🔥

Can’t wait to think about UI behaviours next time I am grinding my teeth at an underground bunker rave. 🕺🕺

banger

Ohh

Making the part developers hate easier 😅🙏

Vercel AI 原神依旧重复制造轮子，放在 vercel-labs 底下的东西哪天直接不维护了都不奇怪 😅

looks fire

this is huge, love the music lol

They've build their own state machine @MalinDhamsara

Addictive demo 🔥, maintained my attention span till the whole end

OH MY GOD

Nice! 🔥🔥🔥

Amazing one vercel

Is this built on Shadcn or replaces it?

Props to whoever chose the music

I hope it will be adapted and will finally fix the problem trying to find my country in the dropdown of 190+ countries.

Congrats on the launch! Giving agents reusable accessibility behaviors feels like a useful foundation for the small, focused tools people build. Excited to see what builders ship with this.

I like it!

Wow this is really neat

This is what @caffeine needs too

Would be helpful to understand the motivation for using this vs BaseUI? It seems more composable but at what cost?

who picked the music its a banger

How is this different from a design system like HIG or Ant? Design system designers have already defined patterns for when a component is appropriate and when it isn't. Arrow behavior should also be built into the drop-down list component.
