Frequently Asked Questions
Does WP Health Inspector offer monthly pricing?
Yes. Monthly plans are available for all four Pro tiers: Starter at $9.99/month (1 site), Studio at $24.99/month (up to 5 sites), Growth at $89.99/month (up to 25 sites), and Agency at $169.99/month (unlimited sites). Annual plans save up to 58% compared to monthly, and 3-year plans save even more.
How much does WP Health Inspector Pro cost?
Pro plans start at $9.99/month or $49.99/year for a single site (Starter). Studio covers up to 5 sites at $24.99/month or $199.99/year. Growth covers up to 25 sites at $89.99/month or $699.99/year. Agency covers unlimited sites at $169.99/month or $1,299.99/year. 3-year licenses are also available at further reduced rates. Every plan includes all diagnostic modules.
What's included in the free Lite version?
The Lite version includes 13 core diagnostic modules: Health Score Dashboard, Error Log & Error Map, What Changed? Timeline Correlation, Autoload Governor, DB Health Inspector, Cron Inspector, Time Bomb Detector, Blast Radius Analyzer, Asset Inspector, Server & PHP Environment, Plugin Abandonment Radar, Mail Health Inspector, and Hosting Benchmark. Free forever — no account, no credit card, no expiry.
What does Pro add over the free version?
Pro unlocks 10 additional modules: Root Cause Analysis, Pre-Update Impact Analysis, Conflict Detector, Request Profiler, External Dependency Monitor, Performance Baselines, Core Web Vitals Estimation, Security Audit, Risk Indicators, and Content Health. It also adds the Export Report (a portable HTML diagnostic report you can send to clients or hosting providers) and upgrades several Lite modules with additional depth.
Is this a subscription or a one-time annual payment?
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.
Is WP Health Inspector safe to run on a live production site?
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.
Can I use one license on a staging site?
Each site activation counts as one site toward your plan limit. Check your plan's site limit before activating on staging or development environments.
What if I need more sites later?
You can upgrade your plan at any time from your Lemon Squeezy customer account.
Does WP Health Inspector send any data to external servers?
No. All diagnostics run entirely on your own server — nothing is transmitted anywhere except to your browser. The only external requests are license validation (via Lemon Squeezy on Pro activations) and the plugin update check, which is standard WordPress behavior.
What PHP and WordPress versions are required?
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.
