Atlassian Browser DevTools is a free extension for Google Chrome that enhances the Developer Tools for inspecting and debugging front-end code of Atlassian products. Developed by Atlassian, this add-on provides a new "ABD" tab in the browser's Developer Tools.

With Atlassian Browser DevTools, users gain access to additional tools specifically designed for inspecting and debugging Atlassian core products and plugins. These tools include the AUI Deprecations Inspector, WRM Inspector, WRM Coverage Browser, and WRM Coverage Recorder.

The AUI Deprecations Inspector allows developers to easily identify and address deprecated code within their Atlassian products. The WRM Inspector provides insights into the Web Resource Manager (WRM) and helps optimize resource usage. The WRM Coverage Browser enables users to analyze the coverage of resources used by their Atlassian products. Lastly, the WRM Coverage Recorder allows for recording and analyzing resource coverage during test scenarios.
