Plugin Compatibility Checker

The Plugin Compatibility Checker helps you keep your WordPress site stable and secure by scanning installed plugins for PHP and WordPress version compatibility. It also alerts you about known plugin vulnerabilities (available via the Portal Dashboard). Free scans are powered by Tide, an open-source project that analyzes plugins and themes for PHP compatibility. This ensures you always have basic compatibility data, even without a license. With a valid license, you unlock advanced compatibility checks up to PHP 8.4, email notifications, and vulnerability insights via the CompatShield Portal. ✨ Key Features
