21st

Find React components, templates, and themes with editable source code

Meet 21st

21st is a searchable library of React interface components, website blocks, templates, and themes contributed by design engineers. Users can browse interactive examples for elements such as navigation, forms, animated hero sections, cards, and backgrounds, then bring the source into their own project. The library follows familiar React, Tailwind, and shadcn/ui conventions.

Components can also be shared with coding agents through a prepared prompt, helping translate a selected example into an existing codebase. Bookmark collections support keeping references for later or sharing them with a team. 21st is useful when a developer wants an inspectable starting point for a particular interaction or visual treatment.
