WP Inspect


The WP Inspect plugin visually annotates pages with the actions & filters (hooks) invoked during the request life cycle.

  • Built-in lucene search engine
  • Toggle hook tracking among header, body, footer & off-canvas contexts
  • Toggle actions, filters & off-canvas hook tracking
  • Ability to ignore hooks by tag
  • Ability to watch/track hooks by tag
  • View hook details such as hook function signature, hook descriptions & syntax-highlighted data structures


  • View Actions & Filters
  • Search Actions & Filters
  • View Filter Stack
  • Search Filter Stack
  • View Hook Details
  • Admin Actions & Filters
  • Hook Argument(s) Highlighting

Currently Completely Broken – Do not try

Activating this plugin killed my site.

[24-Apr-2018 20:18:57 UTC] PHP Fatal error: Out of memory (allocated 1719427072) (tried to allocate 1179648 bytes) in /public_html/wp-content/plugins/wp-inspect/inc/functions.php on line 232

I had to go into the database with phpmyadmin and deactivate my plugins manually to get the site back up.

Table: wp_options
Search for option_name: active_plugins
Double click on option value, delete value, click out of the field to save
GO back in and activate all your other plugins

Great tool for finding available hooks

For months now, several of my colleagues and I are using this plugin for easily finding the right hooks and filters to help our customers out. Great tool to have on your workbench.

Excellent tool

An excellent tool to aid in tracking down errors and helping with proper flow while developing plugins or themes.
