Magento 2 DevTools


An extension for Google Chrome (and likely Mozilla Firefox) that exposes helpful debugging utilities for Magento 2 front-ends.

Early Release

This is a very new project with little to no documentation, published to solicit feedback from early adopters. The extension is currently only available through manual installation of the development build, and will be published to the Chrome Web Store at a future time.



Whenever you navigate to a page running Magento 2, a new tab should appear in DevTools from this extension.

In-Progress Features

  • RequireJS Optimizer configuration generator (including Magento module for quick install)
  • RequireJS module registry inspector

Possible Future Features

  • uiComponents Explorer/Inspector (think React/Angular DevTools)
  • m2 Front-End best-practices checks
