A safe, free default for accessible React components if your team writes its own styles.

What it really isA free, open source React library of accessible component behaviour, with an optional styled theme layer.
Our takeRadix solves the hard part of interface components: focus traps, keyboard support and ARIA wiring for dialogs, menus and popovers.
Primitives leave styling to you, which is ideal for a custom design system and slow for a quick prototype; Themes covers the quick case. Releases continued through July 2026 under WorkOS, so concerns about the project being abandoned do not match the release log.
Why we rate itIt handles accessibility details most teams get wrong, at no cost, with active maintenance.
The catchReact only, and Primitives need you to build every visual style.

  • Teams that must meet accessibility standards

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Short for React developers: install one package and import components.
  2. Scale breakpoint
    Styling effort grows with every Primitive you adopt.
  3. Walled garden
    Low: MIT-licensed code you can fork.
Still a fit?
If none of these block you, start on the free plan.
