Auto-Drafts and Trash Cleanup Tool
Adds Tools > Clean Up Drafts and Trash with counts of leftover auto-drafts, trashed posts and trashed or spam comments, and a button to remove them all permanently after confirmation.
Snippet Library
Performance snippets for WordPress
Snippets that make WordPress lighter and faster: remove emoji scripts and embeds, control the Heartbeat API, limit revisions and load scripts only where they are needed. For developers and site owners chasing better Core Web Vitals.
Autoloaded Options Inspector
Adds Tools > Autoloaded Options showing the total size of options WordPress loads on every page and the 40 largest ones, with a button to stop autoloading any option that does not need it.
Database Table Sizes and Optimize Buttons
Adds Tools > Database Tables listing every table of your site with its row count, data and index size and reclaimable space, sorted by size, with an Optimize button for tables that need it.
Delete Image Size Files No Longer Registered
Adds Tools > Unused Image Sizes, which finds resized copies of your images made for sizes your current theme and plugins no longer register, shows how much space they take, and deletes them in batches after confirmation.
Find What Is Calling admin-ajax.php
Counts admin-ajax.php requests per action (and whether they come from the front end or the dashboard) for the current day and the previous six, and shows the busiest ones under Tools > AJAX Usage.
Find and Remove Orphaned Cron Events
Adds Tools > Orphaned Cron Events, listing scheduled tasks that no active plugin or theme handles any more (often left by uninstalled plugins) and removing them after you confirm.
Log Pages That Run Too Many Database Queries
Records front-end URLs that run more database queries than a limit you set, with the query count and load time, and lists the worst offenders under Tools > Heavy Pages.
Log Scheduled Tasks That Take Too Long
Measures how long each scheduled task (cron event) takes to run and records the slow ones under Tools > Slow Cron Tasks, so you can spot the plugin that makes WP-Cron sluggish.
Log Slow Outgoing HTTP Requests
Times every request your site makes to other servers (update checks, APIs, license servers) and records the ones slower than a second under Tools > Slow HTTP Calls, so you can find what is holding up page loads.
Old Revisions Cleanup Tool
Adds Tools > Clean Up Revisions, which shows how many post revisions your database holds and deletes revisions older than a chosen number of days after you confirm, always keeping the newest few per post.
Orphaned Metadata Cleanup Tool
Adds Tools > Orphaned Metadata, which counts post, comment, term and user meta rows whose post, comment, term or user no longer exists, and removes them after you confirm.
Remove Leftover Data From Uninstalled Plugins
Adds Tools > Leftover Plugin Data, where you enter a prefix (such as old_slider_) to see how many options, post meta, user meta and scheduled tasks use it, and delete them after reviewing the counts.
Server-Timing Header for Administrators
Adds a Server-Timing header with PHP time, database query count and peak memory to pages viewed by administrators, so you can read the numbers in your browser's developer tools Network tab.
