Experimental features and origin trials

Some of the PWA features in Microsoft Edge are still experimental. Experimental features can be used in either of two ways:

  • By enabling the corresponding flag in Microsoft Edge.
  • By enrolling your site in an origin trial to test features in production with your users.

Enroll your site in an origin trial

Microsoft Edge sometimes uses origin trials to test features for specific domains or websites. You may want to use an origin trial for your website to apply a specific feature. If you're a website owner, you can enroll in an origin trial. An origin trial provides features to a percentage of Microsoft Edge users who visit your website.

For more information, see Microsoft Edge Origin Trials.
