Supported browsers

CoreUI supports the latest final releases of all the most popular browsers and platforms.

Alternative browsers that use the newest versions of WebKit, Blink, or Gecko, whether directly or using the platform’s web view API, are not fully supported. But, CoreUI should display and work correctly in these browsers as well. More specific support information is given below.

You can see our supported spectrum of browsers and their versions in our package.json file:


>= 1%
last 1 major version
not dead
Chrome >= 45
Firefox >= 38
Edge >= 12
Explorer 11
iOS >= 9
Safari >= 9
Android >= 4.4
Opera >= 30

We use Autoprefixer to manage intended browser support via CSS prefixes, which uses Browserslist to handle these browser versions.

Mobile devices

CoreUI supports the most modern versions of each major platform’s default browsers. Please see those proxy browsers (such as Opera Mini, Opera Mobile’s Turbo mode, UC Browser Mini, Amazon Silk) are not supported.
