Network Plugin Auditor


As my WordPress network grew I found it challenging to track which plugins and themes were used on each site, and the only way to check was to visit each dashboard one at a time. What a hassle!

This plugin adds columns to your Network Admin on the Sites, Themes and Plugins pages to show which of your sites have each plugin and theme activated. Now you can easily determine which plugins and themes are used on your network sites and which can be safely removed.


  • Plugin Active on the Network Plugins page
  • Plugin Active on the Network Sites page
  • Plugin Active on the Network Themes page


  1. Upload the files to the /wp-content/plugins/ directory.
  2. Network Activate the plugin through the ‘Network Plugins’ menu in WordPress


Will this plugin work with my single-site wordpress installation?

No, the columns are only added in the network admin dashboard. There is no change on the normal site dashboards so there is nothing to see on a single-site installation.

All my blogs are showing blank columns except for the first!

Please update to version 1.2 for improved support for custom database prefixes.

Can I use this plugin as an Must-Use plugin?

Yes! Just copy the network-plugin-auditor.php file to your mu-plugins folder. Be aware that you will not receive automatic notices of updates if you choose to install the plugin this way.

I want to help!

Sure, head over to, fork the repo and send in a pull request!

Great example of simple, important functionality that you’d want in core really. Thanks so much for this. It’s been working fine for years on a couple of high demand multisite networks I run and still working great as of today.

Very useful for knowing what plugins or themes are being used when considering deleting them.

This is an indispensable tool for MS admins, since WordPress core doesn’t include any tools for seeing which MS plugins are in use or by which sites.
