What is Radix UI?

Radix UI provides low-level, accessible, unstyled component primitives — dialogs, menus, popovers — that handle behavior and a11y so you can apply your own styles.

Smart Stack indexes the official Radix UI documentation and keeps it current, so you can search it directly or ask questions in plain language. Because answers are grounded in the real pages — not a model's training data — you get correct, version-aware APIs instead of plausible-looking guesses.

Radix UI — FAQ

What is the latest version of Radix UI?

The latest version of Radix UI indexed in Smart Stack is 1.1.0. Smart Stack re-checks sources on a schedule, so answers stay current with releases rather than relying on a model's training cutoff.

Where can I find the official Radix UI documentation?

The official Radix UI documentation lives at https://www.radix-ui.com/primitives/docs/overview/introduction. Smart Stack indexes it so you can search across it — and the rest of your stack — and get AI answers grounded in those exact pages.

Can I search Radix UI docs together with the rest of my stack?

Yes. That's the core idea behind Smart Stack: add Radix UI to your stack alongside your other tools, and the AI answers questions using the official docs for everything you selected at once — no tab-switching.

Does Smart Stack hallucinate Radix UI APIs?

Smart Stack uses retrieval-augmented generation: it pulls relevant sections from the official Radix UI documentation and grounds the answer in them, which sharply reduces the made-up function signatures you get from ungrounded models.

What works well with Radix UI?

Radix UI is commonly used with tools in the styling css space and adjacent layers of the stack. Add them together in Smart Stack to get integration-aware answers that understand how they fit.
