Main Features

LiteSpeed Web Server (LSWS) is compatible with commonly used Apache features, including mod_rewrite, .htaccess, and mod_security. LSWS can load Apache configuration files directly and works as a drop-in replacement for Apache while fully integrating with popular control panels — replacing Apache in less than 15 minutes with zero downtime. Unlike other frontend proxy-based solutions, LSWS replaces all Apache functions, simplifying use and making the transition from Apache easy while also allowing your team to move confidently with little-to-no retraining.

Control Panel Plugins

LiteSpeed Web Server is compatible with all control panels written for Apache. For some of the most popular control panels, we have developed control panel plugins to allow you to handle common LiteSpeed Web Server processes from within the panel.
