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.

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.
