jal-co/ui is an open-source React component library by Justin Levine. Every component is free, open source, and will never be paywalled.

Components are polished, composable, and built for React and Tailwind CSS. Install them with a single command via the shadcn-compatible registry, or copy the source directly into your project.

npx shadcn@latest add @jalco/[component]

• Open source, never paywalled — every component is free to use, modify, and distribute
• Self-contained — components work without shadcn primitives unless complex interaction justifies it
• Zero dependencies preferred — no Motion, no extra packages unless the payoff is clear
• Server-first — async server components where it makes sense
• Strong defaults — useful out of the box, not a blank canvas

pnpm install        # install dependencies
pnpm dev            # start dev server
pnpm build          # shadcn build + next build
pnpm registry:build # registry only
