21st.dev - Crafted React components and templates, not AI slop | 21st
Hand-crafted React components and templates for building polished user interfaces.
Past Editor's Pick
Each component ships as a copy-paste prompt that rebuilds itself, already themed, inside Claude Code or Lovable. Browsing the library feels like flipping through a design system a careful human actually shipped.

This video shows a fully animated 3D site built in 2 minutes with claude code. one terminal command. but the prompt was almost irrelevant. the real work was the pre-load: ui/ux pro max skill, a hero component from framer motion stacked in before claude touched anything the toolkit did the job. the prompt just pulled the trigger. that's also why most people's claude output looks generic. they skip the setup and blame the model.
