  Radix Primitives is an open-source UI component library for building high-quality, accessible design systems and web apps. Maintained by @workos.

  

Hi HN! I'm Vlad, a designer and engineer on the Radix team (https://radix-ui.com). We just launched Radix Themes, an open source component library for building modern, accessible React apps.

Radix Themes is built on top of Radix Primitives (https://radix-ui.com/primitives), which companies like Vercel, CodeSandbox, and Supabase, among others, already use to power their interfaces.

Our goal is to help you focus on your product and build it faster instead of re-inventing common designs and working on the UI components over and over.

Under the hood, Radix Themes is built with TypeScript, React and vanilla CSS. All design tokens are CSS variables that you can tweak, overwrite, or use to build your own custom components with any styling solution that you like.

The idea to build Radix Themes emerged while working on our own design system at WorkOS (https://workos.com), which is the company behind Radix. There was hundreds of design details and edge cases that we had to take care of, so it still didn't feel like a solved problem.

We also were obsessed with getting the developer experience right. For every component we asked ourselves—what is the right API? What are the right props and parts? What should, and more importantly, shouldn’t be a part of this component? What API would make the code easy to understand and maintain, and what would put you into a messy situation that could bite when you don’t expect it?

With this approach, we used our own, battle-tested components that serve our paying users to kickstart Radix Themes.

I hope that you find Radix Themes useful. Right now, there’s 45 components, hundreds of carefully crafted variants, a few simple and powerful primitives for layout, and an extensive token system.

I would love to hear your feedback on our work and learn about your experiences with building UIs.
