Every Pro plan includes the complete diagnostic suite — Root Cause Analysis, Conflict Detector, Pre-Update Impact Analysis, Security Audit, Core Web Vitals, Request Profiler, Performance Baselines, and more. The only difference between plans is the number of sites.

Think of it this way: If Pro saves you from one avoidable emergency debugging session per year — at $100–$200/hr — it pays for itself on the first incident. For agencies, that math repeats on every client site.
Know what's broken. Know what changed. Know which plugin caused it — on every site you manage.
1 site
The full Pro diagnostic suite on a single site. The easiest way to experience what Root Cause Analysis and Pre-Update Impact Analysis actually look like on your data.
14-day money-back guarantee
Up to 5 sites
For freelancers and small practices. Five activations at $40/site/yr — less than one hour of debugging time.
14-day money-back guarantee
Up to 25 sites
For growing practices. 25 activations at $28/site/yr — cheaper than a single support ticket on most hosting plans.
14-day money-back guarantee

Download Lite for free on WordPress.org — get the full Error Log & Error Map, What Changed? timeline correlation, Blast Radius Analyzer, Autoload Governor, Health Score Dashboard, DB Health, Cron Inspector, Asset Inspector, Time Bomb Detector, and Server & PHP Environment — with no time limit, no account required, and no nag screens.
All of these are included in every Pro plan.
Root Cause Analysis
Names the responsible plugin across all findings, with WP-CLI commands and a deactivation link.
Plugin Conflict Detector
Shows which plugins are fighting over the same hooks, loading duplicate assets, or providing overlapping functionality.
Pre-Update Impact Analysis
Scores every pending update with a 0–100 Blast Radius Score before you click anything.
Request Profiler
Per-request execution time, peak memory, query counts, and hook timeline for deep performance diagnosis.
External Dependencies
Tracks every outbound HTTP call your site makes — surfaces slow or failing payment gateways, APIs, and CDNs.
Performance Baselines
Rolling snapshots of execution time and memory over time — flags regressions automatically.
Core Web Vitals
Server-side LCP, CLS, and INP estimates with Good / Needs Work / Poor ratings and actionable signals.
Security Audit
User & role audit, plugin checksum verifier, and REST API route inspector.
Content Health
Media library integrity, broken reference detection, and rewrite rules inspection.
Risk Indicators
Deprecated function inventory, breaking hooks detector, and plugin compatibility matrix.
Full Export Report
Comprehensive HTML diagnostic report from all modules — shareable without granting admin access.
Every Pro plan is identical in features — only the site count and support level differ.

Yes — 100% read-only. Every query is SELECT, SHOW, or SHOW INDEX. The plugin never modifies your database, runs cleanup routines, or touches user data. It was designed from the ground up to be safe on live production environments — because that's where you need a diagnostic tool most.
All twenty: Health Score Dashboard, DB Health Inspector, Blast Radius Analyzer, Asset Inspector, Cron Inspector, Autoload Governor, Risk Indicators, Time Bomb Detector, Server & PHP Environment, Error Log Aggregation, What Changed? Timeline, Security Audit, Content Health, Core Web Vitals Estimation, Request Profiler, Root Cause Analysis, Conflict Detector, External Dependency Monitor, Performance Baselines, and Pre-Update Impact Analysis — plus a full diagnostic report export. Every plan — Starter through Agency — gets the complete suite. The only difference is the number of site activations and support level.
Yes — all Pro plans come with a 14-day money-back guarantee. If the plugin doesn't meet your needs within 14 days of purchase, contact support for a full refund.
Each unique WordPress installation counts as one site. WordPress Multisite networks count as a single site per network, regardless of how many subsites they contain.
Yes. Lite is a permanently free plugin on WordPress.org — no trial period, no credit card, no account required. You get full access to ten core diagnostic modules: Health Score Dashboard, Error Log Viewer with Error Maps, What Changed? Timeline, DB Health Inspector, Autoload Governor, Blast Radius Analyzer, Asset Inspector, Cron Inspector, Time Bomb Detector (SSL check), and Server & PHP Environment summary. Several modules have expanded functionality in Pro.
Query Monitor and Site Health are development-time tools — best suited for debugging a specific request in real time. WP Health Inspector is designed for diagnosing a site's accumulated state: parsing your full error log, correlating errors with recent changes, attributing database bloat to specific plugins, surfacing overdue cron jobs, and showing you what will happen when you update a plugin. These are complementary tools, not competing ones. Many developers use both.
Eleven modules are fully Pro-exclusive: Security Audit, Content Health, Core Web Vitals Estimation, Request Profiler, Root Cause Analysis, Conflict Detector, External Dependency Monitor, Performance Baselines, Pre-Update Impact Analysis, Risk Indicators, and the full Export Report. Four additional modules — Blast Radius Analyzer, Autoload Governor, Time Bomb Detector, and Server & PHP Environment — offer partial access in Lite with full functionality in Pro.
Yes. The Plugin Compatibility section calls the WordPress.org API once per installed plugin. On sites with 30+ plugins, this can take 10–20 seconds due to external network latency. This is expected behavior, not a bug.
