Module Federation Devtools

There are several browser extensions available to help debug and manage your micro-frontend applications. While we recommend the Zephyr Chrome Extension for the best experience with Zephyr Cloud, the Module Federation Devtools is also a useful option for general Module Federation debugging.

Module Federation Devtools

The Module Federation Devtools Chrome extension offers general Module Federation debugging capabilities:

Key Features

  • Module proxy functionality - Test local modules against remote environments

  • Runtime debugging - Monitor module loading and interactions

Installation
