About

Can I Use is a browser compatibility database that tells you exactly which versions of Chrome, Firefox, Safari, Edge, iOS Safari, and other browsers support a given web technology. It shows global usage share percentages alongside compatibility data, helping you make informed decisions about which features to use or polyfill.

Key Features

💡 Tips

  • For any CSS or JS feature, check the 'Global usage' percentage to understand what share of real-world users are affected by a missing feature.
  • Yellow cells mean partial support or vendor prefix required — click the cell for specific caveats and workarounds.
  • In Settings, exclude browsers you don't support to get an accurate usage share figure for your actual target audience.
