Platform Overviews
shadcn/ui
shadcn/ui is not a traditional npm component library but a collection of copy-paste React components built on Radix UI primitives and styled with Tailwind CSS — developers copy the source directly into their own codebase rather than installing a package, which has made it extremely popular for AI-assisted and rapid-prototyping workflows since 2023. Our engine detects it through 1 HTML pattern matching its characteristic component class-naming and data-attribute conventions inherited from its Radix + Tailwind foundation. Because the code is vendored into each project, signal strength can vary more than with installed libraries. Documented at ui.shadcn.com.
