AssistKit – Site Optimizer Toolkit

AssistKit – Site Optimizer Toolkit is an all-in-one WordPress optimization toolkit designed to improve website performance, strengthen security, simplify administration, and streamline website maintenance.

Unlike plugins that focus on a single area, AssistKit – Site Optimizer Toolkit combines performance enhancements, security hardening, maintenance tools, and administrative controls into one easy-to-use plugin.

Whether you’re a website owner, freelancer, agency, or WordPress maintenance provider, AssistKit – Site Optimizer Toolkit helps you build faster, cleaner, and more secure WordPress websites.

Diagnostics Centre

Run read-only checks that help explain whether important WordPress systems are configured and operating as expected.

WordPress and Site Address configuration
HTTPS and search engine visibility
Environment and debug configuration
REST API and loopback requests
WordPress.org and outbound HTTP communication
Background updates and scheduled events
WP-Cron configuration and recorded update failures
Focused Scheduled Task Health summary
Page cache and persistent object cache
PHP memory limit
WordPress memory limits
Database server version
Maximum upload and POST sizes
Maximum execution time, input time, and input variables

AssistKit distinguishes informational configurations from actual problems. Different frontend and WordPress addresses, disabled visitor-triggered WP-Cron, and hidden search visibility are not automatically treated as failures when they may be intentional.

CRON and Scheduled Task Health

Monitor WP-Cron events and Action Scheduler queues from a dedicated CRON screen without sorting through a raw list of technical hooks.

Detect when the site-wide WP-Cron runner appears stalled, including sites that use an external server cron
Identify overdue recurring events and distinguish a runner-wide problem from individual task concerns
Detect repeated Scheduled Action failures from the last seven days
Detect stalled and substantially overdue Scheduled Actions
Identify high-confidence duplicate WP-Cron schedules and Scheduled Actions
Show task ownership evidence for WordPress core, installed plugins, shared frameworks, and other identifiable sources
Check callback-free hooks against bounded active plugin and theme source evidence before treating them as leftovers
Allow for valid plugins that register some cron callbacks only when work is required
Run a lightweight callback and schedule health observation automatically once per day
Observe callback-free events across three separate automatic checks before identifying them as likely leftovers
Continue monitoring every day after the initial three checks so newly abandoned tasks can still be discovered
Offer guarded leftover-event removal with best-effort undo when the available evidence meets the required confidence threshold
Delete selected failed Action Scheduler history or cancel selected stalled, overdue, and duplicate actions
Keep WordPress core tasks and active conditional plugin tasks protected from inappropriate removal
Hide healthy tasks by default while providing a collapsed read-only reference table of existing tasks
Reflect detected Scheduled Task Health problems in the Diagnostics Centre summary

Database Tools

Use focused Cleanup, Tables, and Options tabs without loading every database scan at once.

Configure post revision, trash, and auto-draft retention
Choose which WordPress cleanup tasks run manually or on the daily schedule
Remove expired transients, spam comments, and orphaned metadata
Clear a stale pre-WordPress 6.4 directory-size transient when it has no valid expiration
Clean expired WooCommerce customer sessions and transients when WooCommerce tables are present
Remove orphaned WooCommerce order items, item metadata, HPOS addresses, and HPOS operational data using conservative parent checks
Clean completed and canceled Scheduled Actions older than 15 days
Optionally remove failed Scheduled Actions older than 60 days
Remove orphaned Scheduled Action logs
Run the saved cleanup selections immediately or schedule them once per day
Review all WordPress-prefixed base table engines, row estimates, and sizes
Detect MyISAM tables and check InnoDB, FULLTEXT, and SPATIAL compatibility
Convert all eligible MyISAM tables to InnoDB or adjust the selected tables first
Process conversions one table at a time with verification and a converted, skipped, and failed summary
Optimize WordPress tables manually, one table at a time, after substantial database changes
Keep table conversion and table optimization out of scheduled cleanup

Autoloaded Options Manager

Review the largest non-protected options WordPress loads automatically and identify settings that may be adding unnecessary database overhead.

View total, manageable, and protected autoloaded option sizes
Review the top 20 manageable autoloaded options by size
Check up to 50 large options against installed plugin, MU-plugin, and theme code, including safely constructed option prefixes
Recognize additional option families from WPCode, Divi, The Events Calendar, Event Tickets, GiveWP, WP Ultimate Post Grid, Formidable Forms, GoodLayers, and Slider Revolution
See the likely source and whether it is active, inactive, or no longer installed
Identify possible orphaned options using cautious ownership matching
Disable autoload without deleting the saved option value
Restore the option’s previous autoload state from AssistKit Changes
Keep option values private and protected WordPress options read-only
