Browser Support

Wire UI supports all modern browsers that support React 19 and standard CSS attribute selectors.

Supported Browsers

Why These Versions?

Wire UI relies on:

• React 19 — requires modern JavaScript engine features (ES2020+)
• CSS attribute selectors — [data-hover], [data-state="open"] — supported in all browsers since IE7, but modern syntax like :focus-visible requires the versions listed above
• :focus-visible pseudo-class — Wire UI’s data-focus-visible attribute mirrors this CSS standard, which was fully supported starting in 2021

No Polyfills Needed

Wire UI does not require any polyfills. If your project supports the browsers listed above, everything works out of the box.

Internet Explorer

Wire UI does not support Internet Explorer. IE was retired by Microsoft in June 2022, and React 19 does not support it either.

Server-Side Rendering

Wire UI is compatible with:

• Next.js (App Router and Pages Router)
• Remix
• Astro (with React integration)
• Any React 19 SSR framework

All components render correctly during SSR. Interactive state attributes (data-hover, data-active, etc.) are added on the client after hydration — they do not cause hydration mismatches.

Mobile Support

All Wire UI components work on mobile browsers with touch events. Touch interactions correctly trigger:

• data-hover on touch start
• data-active on press
• data-focus-visible on keyboard navigation (external keyboard)

Accessibility

Wire UI is tested against NVDA, VoiceOver, and TalkBack. See Accessibility for the full guide.
