The Plugin Compatibility Checker helps you keep your WordPress site stable and secure by scanning installed plugins for PHP, Database, and WordPress version compatibility.
🆕 WordPress 7.0 Database Readiness 
WordPress 7.0 introduces stricter database requirements (MySQL 8.0+ / MariaDB 10.6+). Many hosting environments still run older database versions which may silently block updates. This plugin now detects database compatibility and warns you before upgrading.
$1/month License Required (Entry Plan) 
You must subscribe to the CompatShield Portal ($1/month recurring) to obtain a license key. Once activated, you will be able to see plugin compatibility results (up to PHP 8.5) and database compatibility directly inside your WordPress admin.
📺 Video Tutorial 
Watch step-by-step how to activate your license & run your first scan:

Plugin Compatibility Checker

very helpful to check our plugin compatibility


The plugin checks in free version up to php 8.0+ compatibility. Who needs to know if a plugin is compatible with an obsolete version of php ?


A joke ?


The free version gave me a basic idea, but the paid version was way more useful. It caught PHP issues that I wouldn’t have noticed before updating. Glad I upgraded because it saved me time fixing errors later. Definitely more helpful when running sites on newer PHP versions.


Actually prevented a break on upgrade

Scan and check your WordPress site for PHP, Database (MySQL/MariaDB), and Plugin compatibility to ensure safe upgrades to WordPress 7.0 and beyond.
