Free all-in-one WordPress acceleration plugin with server-level caching on LiteSpeed servers and general optimization features.
Overview
LiteSpeed Cache is a free WordPress acceleration plugin that combines general optimisation tools with server-level page caching for compatible LiteSpeed environments. Features include cache management, image optimisation, CSS and JavaScript processing, lazy loading, database cleanup, object-cache integration, CDN controls, and QUIC.cloud services. Many optimisation features can work on other web servers, but the plugin’s native full-page cache requires LiteSpeed Server, OpenLiteSpeed, or a compatible service. That distinction matters when comparing it with PHP-based caching plugins: the available feature set and likely benefit depend on the hosting stack. It is a strong option for sites already running on LiteSpeed infrastructure, provided settings are tested carefully. WordPress.org currently reports 7+ million active installations. This is a rounded active count for the repository plugin and does not measure the separate adoption of paid LiteSpeed server products.
