Experience the LiteSpeed Difference

Can the software you run make that much of a difference? Yes, it can.

Our lightweight Apache alternative conserves resources without sacrificing performance, security, compatibility, or convenience.

Double the maximum capacity of your current Apache servers with LiteSpeed Web Server's streamlined event-driven architecture, capable of handling thousands of concurrent clients with minimal memory consumption and CPU usage.

Protect your servers with already familiar mod_security rules while also taking advantage of a host of built-in anti-DDoS features, such as bandwidth and connection throttling.

Conserve capital by reducing the number of servers needed to support your growing hosting business or online application.

Reduce complexity by eliminating the need for an HTTPS reverse proxy or additional 3rd party caching layers.

Main Features

LiteSpeed Web Server (LSWS) is compatible with commonly used Apache features including mod_rewrite, .htaccess, and mod_security. As a drop-in Apache alternative, LSWS can load Apache configuration files directly and can fully integrate with popular control panels, including cPanel, Plesk, DirectAdmin, CyberPanel and more. Replacing Apache with LSWS takes less than 15 minutes with zero downtime. Unlike other solutions that act as frontend proxies, LSWS replaces all Apache functions, simplifying use and making the transition to a new server easy for your team. Move confidently forward with little-to-no retraining.
