Overview
LiteSpeed Cache is a free, feature-rich WordPress caching plugin built by LiteSpeed Technologies — the creators of the LiteSpeed web server. On LiteSpeed-powered hosts (including SiteGround and Cloudways), it unlocks server-level page caching that outperforms PHP-based caching plugins. Even on non-LiteSpeed hosts, it provides a solid set of optimisations including image lazy load, CSS/JS minification, and object caching. LiteSpeed Cache integrates with QUIC.cloud for cloud-based critical CSS generation and image optimisation. It consistently outperforms WP Rocket in independent speed tests on LiteSpeed infrastructure.
Key features
- Server-level page caching on LiteSpeed and OpenLiteSpeed servers
- CSS/JS minification and combination
- Image lazy load and WebP conversion
- Object cache with Redis/Memcached support
- ESI (Edge Side Includes) for dynamic content caching
- QUIC.cloud integration for cloud-based critical CSS generation
Common use cases
- B2B site on SiteGround or Cloudways wanting maximum performance without paying for WP Rocket
- Agency managing multiple client sites on LiteSpeed hosts with a free consistent caching solution
- Teams wanting QUIC.cloud for cloud-based image optimisation without a paid caching plugin
Why it matters for B2B
B2B teams on LiteSpeed hosts such as SiteGround or Cloudways who install LiteSpeed Cache get server-level page caching — the same mechanism that premium managed hosts charge for as a proprietary feature. This is the highest-performing free option available for WordPress, directly improving load times for lead generation pages without any additional hosting cost.
