LiteSpeed Web Server — a blazing-fast drop-in replacement for Apache

LiteSpeed Web Server: The Smart Upgrade

Lower Server Load

  • Event-driven architecture instead of the traditional process-based model — LiteSpeed handles more users without requiring server upgrades 
  • Efficiently manages thousands of connections with minimal CPU and memory usage
  • Keeps websites fast and responsive even during peak traffic

Security & Compatibility

  • Fully compatible with Apache configurations: .htaccess, mod_rewrite, and mod_security
  • Built-in protection against brute force login attacks
  • Optimizes WordPress by caching pages, compressing resources, speeding up load times, and improving Core Web Vitals

Modern Protocols & Technologies

  • Supports HTTP/3 and QUIC — speeds up website loading on unstable connections and mobile devices
  • Secure connections with TLS 1.3 and faster load times thanks to Brotli compression
  • Asynchronous request processing — handles more connections with less server load

Infrastructure Savings

  • LSWS uses fewer resources, thus reducing hosting and hardware costs
  • Fewer crashes and overloads, combined with a simple setup, result in lower support expenses
  • Runs reliably even on servers with limited resources

  • Improves Core Web Vitals, which helps your rankings on Google
  • Speeds up loading of both static and dynamic content for WordPress, Joomla, OpenCart, and other CMS platforms

Seamless integration with your hosting panel
