Ember.js Browser Support Policy

Ember 3.0.0

Ember currently targets Internet Explorer 11 as a baseline for support. This means that generally all modern and relatively recent browsers will work with Ember, since browsers are backwards compatible by design. Ember runs tests against the latest desktop versions of the following browsers:

  • Google Chrome
  • Mozilla Firefox
  • Microsoft Edge
  • Internet Explorer 11
  • Safari

Ember 4.0.0

In Ember 4.0.0, the framework will support the following major browsers:

  • Desktop
    • Google Chrome
    • Mozilla Firefox
    • Microsoft Edge
    • Safari
  • Mobile
    • Google Chrome
    • Mozilla Firefox
    • Safari
  • Testing
    • Google Chrome
    • Mozilla Firefox

Other browsers may work with Ember.js, but are not explicitly supported. If you would like to add support for a new browser, please submit an RFC or RFC issue for discussion!

We determine support on a browser-by-browser basis. Browsers are categorized as either evergreen or non-evergreen. The categorization is as follows:

Evergreen

  • Desktop
    • Google Chrome
    • Mozilla Firefox
    • Microsoft Edge
  • Mobile
    • Google Chrome
    • Mozilla Firefox
  • Testing
    • Google Chrome
    • Mozilla Firefox

Non-evergreen

  • Desktop
    • Safari
  • Mobile
    • Safari

For evergreen browsers, the minimum version of the browser that we support is determined at the time of every minor release, following this formula:

Whichever browser version is greater/more recent out of:

  1. The lowest/least recent version that fulfills any one of these properties:
    • It is the latest version of the browser.
    • It is the latest LTS/extended support version of the browser (such as Firefox ESR).
    • It has at least 0.25% of global marketshare usage across mobile and desktop, based on statcounter.
  2. The minimum version supported in the previous release

To simplify, the supported version either moves forward or stays the same for each release based on overall usage and LTS/current release versions.

For non-evergreen browsers, support is locked at a specific major version, and we support all major versions above that version:

  • Desktop
    • Safari: 12
  • Mobile
    • Safari: 12
Within a version of a browser, we only support the most recent patch release.
