Platform Overviews
Radix UI
Radix UI is an unstyled, accessibility-first React primitives library that underlies many modern design systems, including shadcn/ui — it provides the interaction logic and ARIA behavior for components like dialogs, dropdowns, and popovers, leaving all visual styling to the implementing site. Our engine detects it through 2 HTML patterns tied to its data-attribute and ARIA-state conventions, since Radix ships no distinctive bundled script signature of its own — detection relies entirely on the markup its primitives generate at runtime.
