LiteSpeed Cache review
A free, open-source WordPress optimizer whose caching depends on LiteSpeed or QUIC.cloud.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
LiteSpeed Cache is a free, open-source plugin for optimizing self-hosted WordPress sites. It is aimed at site owners who want caching alongside image, script, database, and object-cache tools in one plugin. Multisite users can also access network-level settings. Its strongest fit is a WordPress installation on LiteSpeed Web Server or OpenLiteSpeed, or one using QUIC.cloud CDN; owners on other server software can use some optimization features, but not the plugin’s caching features without supported infrastructure.
Caching is the central distinction. The plugin connects WordPress to LiteSpeed Web Server’s cache module for full-page caching and purges, with private caching for logged-in users, Edge Side Includes, and a crawler that revisits expired pages. Image optimization and lazy loading, CSS and JavaScript page optimization, database optimization, and object-cache support broaden its scope beyond page cache. Integrations include WooCommerce, Elementor, Divi, WPML, Contact Form 7, and Yoast SEO, as well as QUIC.cloud CDN. This makes it relevant to varied WordPress setups, but cache benefits are tied to the supported LiteSpeed or QUIC.cloud environment.
The plugin itself is free, and its source is open. That does not mean every part of the setup is cost-free: some QUIC.cloud services charge at certain usage levels, and LiteSpeed server editions may have fees. Support is available through tickets, community resources, and documentation. Choose LiteSpeed Cache if you want a broad, free WordPress optimization toolkit and can use its supported caching infrastructure. If you need its caching features while staying on unsupported server software, it is not the right fit; the optimization features that work with other server software may still be relevant.
