About

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.

Install

npx shadcn@latest add @jalco/[component]

Browse all components at ui.justinlevine.me/docs.

Design principles

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

Local development

pnpm dev            # start dev server
pnpm build          # shadcn build + next build
