Accessible, customizable React component collection built on Radix UI and Tailwind CSS, distributed as copy-paste source code, free.
shadcn UI changed how you consume a component library. Instead of installing an npm package you're stuck with, you copy the component code straight into your project via a CLI (npx shadcn add). The code is yours: you edit it however you want, without fighting a closed library's style overrides. It's built on Radix UI for accessibility and Tailwind CSS for styling.
In a few years it has become the default choice for modern React projects, and for good reason: you keep full control, you don't have a dependency that breaks at the next major update, and the look is clean and easy to customize. It's free and open source.
The flip side: you need Tailwind, it's React only, and since you own the code, maintaining the components is on you (no automatic updates). For a fresh React + Tailwind project, it's hard to beat. If you want very opinionated, ready-made components, Material-UI or Ant Design are more turnkey.

Excellent
shadcn/ui is entirely free open-source code with no license to buy, so any time saved building accessible components is rentabilized immediately.
Components are copy-pasted directly into a React and Tailwind project, which is designed to produce a usable result without installing a package manager dependency first.
The library delivers accessible, customizable components built on Radix UI primitives as promised, confirmed on the official home page.
Full ownership of the copied source code lets a team customize components beyond what a packaged library typically allows, within the category.
Components are copied as plain source code owned by the developer, with no runtime dependency on shadcn/ui itself, making it fully portable.
