Origin UI

This page collects the Origin UI components published on 21st — a large set of copy-paste React building blocks built with Tailwind CSS on shadcn/ui conventions, best known for its depth in form controls and everyday interface elements. Every component here renders in a live preview, so you can test behavior before copying anything.

Use the collection to compare variants quickly, then copy the TSX, install via the shadcn CLI, or pull components into Cursor or Claude Code through MCP. Since the markup follows shadcn/ui patterns, pieces slot into an existing project without restyling.
