If your website is hosted on a LiteSpeed server — which includes many popular hosts like Hostinger — then LiteSpeed Cache is the best and most powerful free caching plugin available. It delivers WP Rocket-level performance at absolutely no cost.
What Is LiteSpeed Cache?
LiteSpeed Cache is a free WordPress caching plugin that works at the server level when used on LiteSpeed-powered hosting. This server-level integration makes it significantly faster than PHP-based caching plugins. It also works on non-LiteSpeed servers as a standard caching plugin, though with reduced effectiveness.
Key Features
- Server-Level Caching — Works directly with the LiteSpeed web server for maximum performance.
- Image Optimisation — Built-in image compression and WebP conversion (using their QUIC.cloud CDN).
- CSS/JS Minification — Reduces file sizes for faster loading.
- Lazy Loading — Images and iframes load only when needed.
- Database Optimisation — Cleans up WordPress database automatically.
- CDN Support — Works with QUIC.cloud CDN (free tier available) and other providers.
- Object Caching — Caches database queries for even faster performance.
LiteSpeed Cache on Hostinger
Hostinger uses LiteSpeed servers, which means LiteSpeed Cache runs at full power on their hosting plans. This makes it the ideal performance solution for Hostinger websites — and it’s completely free. Combined with Hostinger’s built-in caching, your website will load exceptionally fast.
Is It as Good as WP Rocket?
On LiteSpeed servers, yes — LiteSpeed Cache can match or even exceed WP Rocket’s performance. On other servers, WP Rocket is generally more effective. If you’re on Hostinger or another LiteSpeed host, use LiteSpeed Cache and save yourself the WP Rocket licence fee.
LiteSpeed Cache is the best free performance plugin for WordPress. If your host supports it, there’s no reason not to use it.
