Overview
LiteSpeed Cache for WordPress (LSCWP) is a free plugin from LiteSpeed Technologies, the company behind the LiteSpeed Web Server and its open-source OpenLiteSpeed edition. It was added to the WordPress.org directory in January 2016 and in November 2026 reported 7+ million active installations, the largest figure of any plugin in this list.[3]
The plugin combines two groups of features. General features work on any web server, including Apache and NGINX: object-cache support for Memcached, LSMCD and Redis, image optimisation, minification and combination of CSS and JavaScript, automatic critical CSS, lazy loading, deferred JavaScript, database cleanup and Cloudflare API integration.[3] The headline server-level page cache is a LiteSpeed-exclusive feature that requires OpenLiteSpeed, a commercial LiteSpeed product, LiteSpeed-powered hosting or the QUIC.cloud CDN.[3] Several cloud features, such as image optimisation and critical CSS generation, run through QUIC.cloud, LiteSpeed’s CDN and optimisation service.[4]
LSCWP supports WordPress Multisite and is compatible with WooCommerce, bbPress and Yoast SEO, and it also works with ClassicPress.[3] The changelog for version 7.9.3 (3 November 2026) lists a forthcoming 8.0 release built around a feature named OptiMax.[3] Its documented limitation is dependence on the hosting stack: on Apache or NGINX servers without QUIC.cloud, the plugin’s most important caching feature is unavailable.
