Which browsers/versions are required for the Web SDK?

Due to the advanced features required and some limitations imposed by operating systems, not all browsers are able to correctly use this library.  With increasing adoption of iOS 11, we expect to have more than 85% of browser coverage in US and Europe.


  - Chrome 57+

  - Firefox 52+

  - Opera 44+

  - Safari 11+ (except 11.2.2-11.2.6.  See here)

  - Edge 16+

Mobile - Android

  - Chrome 59+

  - Firefox 55+

Mobile - iOS

  - Safari 11+


The following is a list of the main required features together with links to updated support stats:

Please note, that at this time, the Web SDK is only partially supported in webviews of other apps.  More info here:
