What browsers does AngularJS work with?

For every code change, we run our extensive test suite against the following browsers:

• The latest stable version of Google Chrome.
• The latest stable version of Mozilla Firefox.
• The latest stable version of Safari.
• The latest stable version of Microsoft Edge.
• Internet Explorer versions 9, 10, and 11. See the Internet Explorer Compatibility guide for more details on supporting legacy IE browsers.

Additionally, every two weeks we run tests against the following browser versions:

• The latest 2 stable versions of Google Chrome.
• The latest 2 stable versions of Mozilla Firefox.
• The latest 2 stable versions of Safari.
• The latest 2 stable versions of Safari for iOS.
• The latest 2 stable versions of Microsoft Edge.

Finally, in order to proactively catch and fix browser compatibility issues, every week we run tests against the following unstable browser version:

• Google Chrome Beta
• Mozilla Firefox Beta
• Microsoft Edge Beta

If a browser is untested, it doesn't mean it won't work. You can also expect browsers to work that share a large part of their codebase with a browser we test, such as Opera 15 or newer (which uses the Blink engine), or the various Firefox derivatives.
