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.
Cache Site-Wide Comment Counts
Stores the comment totals that WordPress shows in the admin menu, toolbar and dashboard for 10 minutes, avoiding a slow counting query on every admin page view on sites with many comments.
Cache User Counts on Large Sites
Caches the per-role user counts shown on the Users screen and dashboard for 12 hours, avoiding a heavy query on sites with many users.
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.
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.
Keep Speculative Loading Away From Cart, Checkout and Account Pages
Tells WordPress's built-in speculative loading (prefetching pages on hover) to skip cart, checkout and account pages, which are personal, never cached and expensive to build, so hovering over their links no longer costs server time.
Load the WooCommerce Password Strength Meter Only When Needed
Removes the password strength meter script (about 400 KB with its dictionary) from every page except the account, checkout and password reset pages where customers actually choose a password.
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.
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.
Remove Orphaned Term Relationships and Fix Term Counts
Run on demand to delete category and tag links that point to posts that no longer exist, and then recount how many posts each term has.
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.
