The most popular WordPress caching plugin, trusted by 3M+ sites for page speed optimisation.
Speed matters. This hub covers caching, image optimisation, code minification, and database cleanup — every plugin that makes your WordPress site measurably faster.
WordPress performance plugins range from full-page caching solutions to specialised tools that target a single bottleneck — image size, render-blocking CSS, or database bloat. Our reviews test each plugin on a shared hosting environment with a stock Astra + WooCommerce setup, measuring Core Web Vitals before and after activation.
Every score on this page follows the WPCatalog methodology: seven weighted criteria, publicly documented, with every price and version timestamped to the day of verification. No paid placements — scores are earned, not bought.
