Quick verdict on LiteSpeed Cache
LiteSpeed Cache is the highest-leverage caching plugin you can install if your host runs LiteSpeed servers. Unlike WP Rocket or W3 Total Cache (which cache at the WordPress application level), LiteSpeed Cache integrates with the LiteSpeed web server to cache at the server level — which is dramatically faster. On a LiteSpeed-based host (Hostinger, most of Bluehost, A2 Hosting Turbo plans, NameHero, ChemiCloud), LiteSpeed Cache is genuinely competitive with WP Rocket while being completely free. On Apache or Nginx hosts, LiteSpeed Cache still works as an application-level cache but loses its biggest performance advantage — at that point, the choice between LiteSpeed Cache and WP Rocket is closer. The QUIC.cloud CDN integration adds a free CDN tier (with paid upgrades) — useful for sites with global audiences. Hostinger users specifically should install LiteSpeed Cache before considering any paid caching plugin.
