Refero Stylesshadcn/ui21st.dev
Quick read
- Free with no card: Refero Styles, shadcn/ui.
| Field | Refero Stylesstyles.refero.design | shadcn/uiui.shadcn.com | 21st.dev21st.dev |
|---|---|---|---|
| What it is | 2,000+ design systems reverse-extracted from real production sites and packaged as structured DESIGN.md files documenting colors, typography, spacing and motion. Filter by brand, mood (minimal, editorial, playful), palette or typeface. | 50+ accessible components built on Radix (now Base UI by default) and Tailwind, distributed as source copied into your repo rather than an npm dependency. Also ships Blocks, Charts, a Themes browser, and the registry protocol. 121k stars. | 12,000+ React/Tailwind components in native shadcn registry format, plus ~50 community themes, 29,000 searchable icons, shaders and gradients. Every item exposes an AI-ready prompt written specifically for Lovable, Cursor and Claude Code. |

| Why builders pick it | The single highest-leverage free thing on this list. Instead of telling Claude 'make it feel editorial', hand it exact tokens from a site whose type you admire. Filter by the editorial mood, paste the DESIGN.md as project context, then have Lovable generate to those tokens. An official Refero MCP and two community MCP servers exist. | This is already your project. The reason it matters strategically: React Bits, 21st.dev, Magic UI, Kokonut and ElevenLabs UI all publish into its registry, so wiring the official shadcn MCP once gives Claude an install path into every one of them. | The themes page is the fastest visual win you have. A theme here is a shadcn token set — colors, type, radius. Copy the :root/.dark blocks into index.css and the whole app re-skins with zero component edits. Browse the themes page and pick one that matches the look you are already going for. |
