Health Radar is a comprehensive WordPress plugin auditing and health monitoring tool for site administrators. Get a clear, real-time picture of their site’s plugin ecosystem—conflicts, performance bottlenecks, compatibility issues, and errors—without guessing or digging through logs.

Stop managing plugins blindly. Stop performance issues before they impact your users. Stop compatibility problems from becoming critical failures.

Core Features:

🔍 Plugin Conflict Detector — Instantly detects duplicate script and style handles, identifies hook collisions between active plugins, and highlights which plugins are fighting for the same resources.
⚡ Performance Insight Panel — Measures total enqueued assets, calculates JS/CSS payload, counts database queries (when SAVEQUERIES enabled), audits wp_options autoload bloat, and generates a 0–100 health score with actionable recommendations.
🐘 PHP Compatibility Checker — Validates each plugin’s Requires PHP header against your server version, scans for deprecated WordPress function usage, and flags incompatible plugins before they break your site.
📋 Debug Log Analyzer — Intelligently parses wp-content/debug.log, categorizes errors as fatal, warnings, or notices, attributes errors to specific plugins via stack trace analysis, and shows trends over time.
🧬 Duplicate Asset Detector — Uses file fingerprinting (MD5) to identify identical JavaScript and CSS libraries loaded by multiple plugins (detects jQuery, Lodash, Moment.js, Chart.js duplicates, and more).
📄 Health Report Generator — Compiles a full site health snapshot into a single printable page; export as JSON for automation, or generate PDF from browser print dialog.

WP-CLI Integration:

Automate plugin health audits and reporting via command line:

wp healthmonitor scan — Trigger a full plugin health scan and display results.
