Can I Use Browser Support — free online tool

Search open browser-support tables before adopting CSS grid, WebP, or a new JavaScript API in production.

Saves opening a terminal or a separate DNS client for one-off checks.

How to use Can I Use Browser Support

  1. Type a CSS property, HTML element, or API name into the Can I Use search field.
  2. Wait for the open dataset to load matches in your browser.
  3. Open a feature to read global support percentages and browser notes.
  4. Follow the external caniuse.com link from results when you need full detail.

Practical tips

  • Check support before adopting a feature so you know whether you need a fallback.
  • Look at the versions your real audience uses, not just the global percentage.
  • Pair a "partial support" result with a quick test in the specific browser that worries you.

Limitations

Can I Use Browser Support relies on public APIs that may rate-limit, cache, or return approximate geolocation. Do not send secrets or internal hostnames.

Privacy & data
