OpenLiteSpeed (OLS) is its open-source variant. Both speak HTTP\/1.1, HTTP\/2, and HTTP\/3 (QUIC), support TLS 1.3, and integrate tightly with PHP via LSAPI for lower latency than PHP-FPM under heavy load.<\/p>\n<\/div><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"1168\" height=\"784\" src=\"https:\/\/www.youstable.com\/blog\/wp-content\/uploads\/2025\/12\/What-Is-LiteSpeed-Web-Server.png\" alt=\"What Is LiteSpeed Web Server?\" class=\"wp-image-13204 size-full\" srcset=\"https:\/\/www.youstable.com\/blog\/wp-content\/uploads\/2025\/12\/What-Is-LiteSpeed-Web-Server.png 1168w, https:\/\/www.youstable.com\/blog\/wp-content\/uploads\/2025\/12\/What-Is-LiteSpeed-Web-Server-150x101.png 150w\" sizes=\"auto, (max-width: 1168px) 100vw, 1168px\" \/><\/figure><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"enterprise-vs-openlitespeed\"><strong>Enterprise vs OpenLiteSpeed<\/strong><\/h2>\n\n\n\n<p>LiteSpeed Enterprise is a licensed, drop-in Apache replacement with full .htaccess and mod_security compatibility, cPanel\/DirectAdmin\/Plesk integration, and advanced features for shared hosting. OpenLiteSpeed is free and very fast, but has some .htaccess differences and focuses on virtual host-level configs.
