WP Rocket

WP Rocket – The Leading WordPress Caching Plugin

WP Rocket is a top-tier WordPress caching plugin with a stellar reputation. Beyond its core caching capabilities, it optimizes database tables on command and can automatically clean up your database on a daily, weekly, or monthly schedule. While dedicated WordPress database optimization tools exist, letting WP Rocket handle this is far more convenient than installing yet another plugin.

WP Rocket also excels at front-end optimization. In addition to basic features like JS/CSS minification (CSS concatenation was removed in v3.15 due to being outdated), it supports lazy loading, deferred loading, asynchronous CSS loading, and Critical Path CSS generation—features that have earned widespread praise.
