  • Once the JSON is copied it generates a friendly Diff User interface that highlights the differences

WordPress Website Plugins Compare

Developers usually have multiple instances running of the same website on different environments such as their local machines, development or test servers as well as production environments.

As development goes on a project or as support requests get fulfilled the plugins installed on these various environments could get out of sync.

Version control systems such as Git are great but they were designed to track differences between files not lists of installed plugins and their state in the Database.

This plugin does not rely on version control systems and since it exports the list a simple JSON it has no limitations on which two websites you compare.

  • Copy this JSON from here and paste it in the other website.
  • You can label and tag your environments to help better distinguish between them.
