Radix UI
Radix UI is an open-source component library for building accessible, high-quality design systems and user interfaces in React applications. It provides a collection of low-level, unstyled, and fully accessible UI primitives such as dialogs, dropdowns, and tooltips, allowing developers to customize styles while ensuring robust accessibility out-of-the-box. The library emphasizes developer experience with features like TypeScript support, headless components, and a focus on WAI-ARIA compliance.
Developers should use Radix UI when building React applications that require accessible, customizable UI components without being tied to a specific design system or styling framework. It is ideal for projects where you need fine-grained control over styling (e.g., using CSS-in-JS or Tailwind CSS) while maintaining accessibility standards, such as in enterprise applications, design system implementations, or any product prioritizing inclusivity. Its headless approach makes it a strong choice for teams that want to avoid the bloat of pre-styled component libraries.
