PayPal vs Adyen vs Klarna Magento Extensions: Which Are Actually Maintained in 2026?
Most extension comparison posts age out in six months. This is an annual maintenance audit of the three biggest payment extensions for Magento (PayPal Commerce Platform, Adyen Magento Plugin, and Klarna Payments), measured across five hard axes: GitHub commit velocity in the last 90 days, Magento Marketplace average rating, open-to-closed issue ratio, real support response time, and PHP 8.4 + Magento 2.4.9 compatibility status. Each extension gets a maintainability score and a recommendation by store size segment. Updated quarterly.
