About LiteSpeed Web Server

LiteSpeed Web Server is a high-performance, low-resource web server designed as a drop-in replacement for Apache.

LiteSpeed Web Server is a commercial web server software developed by LiteSpeed Technologies. It is engineered as a high-performance, low-resource drop-in replacement for the widely used Apache web server. Its core is an event-driven architecture, allowing it to serve a high volume of concurrent connections efficiently. Key features include native support for modern protocols like HTTP/3 and QUIC, a powerful built-in page cache (LSCache) with plugins for popular applications like WordPress and Magento, and robust security measures including anti-DDoS protection. It is compatible with major control panels like cPanel and Plesk, making migration straightforward for hosting providers and site owners. The product offers a free tier for single domains, with paid plans scaling based on domains, workers, and memory. A 15-day free trial is available for evaluation.
