It's an annual license — you pay once per year. If you don't renew, the plugin keeps working on sites where it's already installed; you just won't receive future updates or access priority support.
Yes. Every single database query is SELECT-only. The plugin never writes, updates, or deletes a row of data — no cleanups, no auto-fixes, no risk. It was designed from the ground up to be safe on live production sites.
Each site activation counts as one site toward your plan limit. Check your plan's site limit before activating on staging or development environments.
You can upgrade your plan at any time from your Lemon Squeezy customer account.
Core diagnostics run inside WordPress. When Fleet Sync is configured, selected diagnostic findings can be shared to another WordPress instance you control. Pro also communicates with Lemon Squeezy for license validation, and WordPress performs its standard plugin update checks.
WP Health Inspector requires PHP 8.0 or later and WordPress 6.0 or later. Both the Lite and Pro versions have the same requirements.
Download the Lite version from WordPress.org and install it like any other plugin. 15 diagnostic modules, no registration, no trial expiry — just install and run.
In minutes you'll see your site's health score, any active error log issues, autoload bloat, cron job status, and everything else the Lite suite covers.
Pro adds 14 modules — Root Cause Analysis, Plugin Health Check, Conflict Detector, Security Audit, and more — plus expanded reports you can hand directly to clients or hosting providers.
Packages available with Monthly, Annual, and 3 year license terms.
