Animated Health Gauge
A top-level 0–100 score that grades your site across its most impactful performance and safety dimensions — refreshed on demand via AJAX.
WP Health Inspector traces each error back to the issue that caused it, and shows you exactly which recent update, code change, or environmental change triggered it — all without touching a single row of your data.
Ten core diagnostic modules free, forever. Ten Pro-exclusive modules — including Root Cause Analysis, Pre-Update Impact Analysis, and Plugin Conflict Detection, as well as additional functionality added to select free modules. — unlock when you're ready to go deeper. One health score. Zero risk.
100% read-only · No data sent anywhere · WordPress.org listed
PHP errors pile up unread. Plugin updates break things with no obvious connection. Autoloaded options silently bloat. Cron jobs fail in the dark. Every day without visibility is a day the problems get harder to untangle — until a client calls and the emergency clock starts.
Your Health Score
An animated 0–100 gauge that grades your site across performance, security, and stability dimensions — computed from live data the moment you open it.
Your Actual Error Count
How many PHP errors are in your log right now, grouped by severity. Most sites have more than their owners realize — and several will be actively affecting visitors.
The Fastest Path to Your Problem
The dashboard reads your live data and surfaces the 2–3 diagnostic paths most likely to lead you to your current issue — in the right order, with specific errors from your log.

Generate a comprehensive HTML diagnostic report from all available modules and hand it to a client, a colleague, or your hosting provider — without sharing credentials, recording your screen, or writing a single word yourself. Self-contained, portable, and immediately useful. Pro users get a full expanded report across every module. Lite users get a focused core summary.
These aren't edge cases. None of this is unusual. Through active monitoring, ALL of it is preventable.
Fixing problems you don't understand is risky. This plugin makes those risks visible.
This is professional diagnostic tooling — built to reveal and explain WordPress issues in depth, not automate solutions you don't understand. Completely non-invasive. It gives you the information you need to make informed decisions, fast.
Right now, your site is almost certainly throwing PHP errors nobody is reading. A plugin updated last week may be the cause — but without error log correlation, you'll never connect those dots. A single bloated autoload table adds hundreds of milliseconds to every page load. A failing cron job queues silently and spikes on the next visitor. A conflict between two plugins makes both unreliable in ways that are impossible to reproduce consistently.
The difference between a five-minute fix and a weekend emergency is knowing the problem exists, knowing which plugin caused it, and knowing what changed.
WP Health Inspector gives you that knowledge — without the risk of touching anything.
Yes — 100% read-only. Every query is SELECT, SHOW, or SHOW INDEX. The plugin never writes, updates, or deletes anything. No cleanup routines, no auto-fixes, no risk. It was designed from the ground up to be safe on live production sites — because that's where you need it most.
The free Lite version includes ten core modules: Error Log Viewer, What Changed? Timeline, DB Health Inspector, Autoload Governor, Blast Radius Analyzer, Asset Inspector, Cron Inspector, Time Bomb Detector, Server & PHP Environment, and Health Score Dashboard.

The plugin uses file-path matching as the primary attribution signal: if a PHP error originates inside an updated plugin's folder, the correlation is scored 80–99 out of 100 (near-certain attribution). It also tracks every plugin update, activation, and WordPress core update as a timestamped event and correlates them against error frequency spikes on the What Changed? timeline.
No. Install it from WordPress.org, activate it, and it works immediately. No account, no email signup, no trial period, no nag screens, no data sent anywhere. The Lite version is free forever.
Yes. Several modules are particularly useful on WooCommerce sites: Cron Inspector surfaces overdue Action Scheduler jobs (a common cause of order processing delays), Error Log Viewer identifies WooCommerce-specific PHP errors with tailored fix steps, and Pre-Update Impact Analysis (Pro) scores WooCommerce and payment gateway updates with a Blast Radius Score before you touch them.
