WP Health Inspector shows you what broke your WordPress site — and what changed right before it did. Every plugin update, activation, and core change is plotted against your PHP error spikes and scored 0–99, so you stop guessing which change caused the problem. And because every query is read-only, it is completely safe to run on a live production site.
Think of it as a medical chart for your WordPress install. It surfaces findings, flags issues, and helps you trace the root cause of problems — but it never acts without your permission. Every database query is SELECT-only. Nothing is inserted, updated, or deleted.
Who it’s for
- Site owners who want to understand why their site is slow or broken
- Developers debugging PHP errors and plugin conflicts
- Agencies doing pre-launch or ongoing site audits
- Anyone who wants to stop guessing and start knowing
The Modules
🔴 Error Log Viewer
PHP error log analysis — grouped, severity-rated, and sorted so you see the most important errors first. Each group shows first-seen and last-seen timestamps, occurrence count, file path, and line number. The viewer also detects whether your debug log is web-accessible and escalates the health score if so.
📅 What Changed? — Timeline Correlation
The most useful debugging tool on this list. Every plugin update, activation, WordPress core update, and theme switch plotted on the same interactive timeline as your PHP error spikes. Hover any event to see correlation scores (0–99) with plain-English reasoning explaining why a change and an error are likely connected.
🗄️ DB Health Inspector
Table bloat analysis, autoloaded options ranked by size, orphaned postmeta counts, Action Scheduler history, and autoload index verification. If your database is slowing you down, this is where you find out why.
⚙️ Cron Inspector
Standard WP-Cron and Action Scheduler jobs in a single unified view, sorted chronologically with next-run times, intervals, and overdue highlighting. No more mystery cron tasks.
🔌 Blast Radius Analyzer
Shows the full footprint of every active plugin: custom database tables, scheduled cron jobs, REST API routes, enqueued scripts and stylesheets, and hook registrations. Know exactly what a plugin owns before you deactivate it.
🚀 Update Impact
Before updating any plugin, see what it shares with the rest of your site — common hooks, custom DB tables, scheduled jobs, REST endpoints, and asset bundle size — so you can anticipate conflicts before they happen.
📦 Autoload Governor
Per-plugin autoload size attribution. See exactly which plugins are adding weight to every single page load, and how much.
💣 Time Bomb Detector
SSL certificate expiry monitoring, PHP version risk assessment, and stale plugin flagging. Problems that tend to surface at the worst possible time — surfaced early, on your schedule.
🕵️ Plugin Abandonment Radar
Every installed plugin cross-checked against the WordPress.org Plugin API for last-updated staleness, tested-up-to drift, and closed or removed status. Closed plugins are often removed for unpatched security vulnerabilities — this module tells you before it becomes a problem.
📜 Asset Inspector
Every script and stylesheet WordPress has enqueued, with file sizes and running totals, separated by JavaScript and CSS.
🖥️ Server & PHP Environment
php.ini directive audit, key wp-config.php constants review, PHP extension checklist, and database server details — all in one place.
📊 Hosting Benchmark
On-demand database, PHP, and filesystem performance probes with letter grades and object-cache detection.
✉️ Mail Health Inspector
WordPress mail transport detection, live SPF/DKIM/DMARC/MX DNS record checks, and a one-click send test that returns real failure messages instead of generic errors.
📄 Export Report
Generates a self-contained, downloadable HTML diagnostic report covering the health score, database metrics, error log summary, and full system snapshot. Shareable with hosting support or a developer without granting admin access.
100% Read-Only
Every query this plugin runs is SELECT-only. It reads your site’s state; it never changes it. No rows inserted, no settings modified, no plugins deactivated.

External Services
This plugin connects to the official WordPress.org Plugin API to power the Plugin Abandonment Radar module.
What it does: for each installed plugin, the plugin requests that plugin’s public directory listing (last-updated date, tested-up-to version, and open/closed status) from the WordPress.org Plugin API, so it can flag plugins that appear abandoned or removed.
When it happens: only when an administrator views the Plugin Abandonment Radar page. Results are cached for 12 hours between requests.
Data sent: only the plugin slugs of plugins already installed on your site. No site content, user data, or personally identifiable information is sent.
