Three Steps to 10x Performance

1

Run One Command

SSH into your server and run the install command. It auto-detects your panel, downloads OpenLiteSpeed, and starts the migration.

2

Auto-Detect Everything

The installer reads your existing Apache config natively. VHosts, SSL certs, PHP versions, proxy rules, rewrites -- all detected automatically.

3

Instant Performance

All your sites work immediately with 10x faster performance. LSCache for WordPress is ready out of the box. HTTP/3 is enabled by default.

Everything Migrates Automatically

Your entire Apache configuration is read natively and translated to OpenLiteSpeed. Nothing is left behind.

Native Apache Config Reading

Reads httpd.conf, VirtualHost blocks, IfModule directives, Include chains, and SSL configuration directly. No conversion scripts needed.

Built-in LSCache

WordPress page caching out of the box. Install the LiteSpeed Cache plugin and get instant full-page caching without any server configuration.

Auto PHP Detection

Detects PHP versions from ea-php, alt-php, plesk-php, FPM sockets, FCGIWrapper, and AddHandler directives. All versions from 5.6 to 8.3+.

SSL Pass-Through

Existing SSL certificates work immediately. SSLCertificateFile and SSLCertificateKeyFile are read and applied to OpenLiteSpeed listeners. Let's Encrypt renewal continues.

One-Click Revert

Run the uninstall command and Apache is restored instantly. Your original configuration is preserved and nothing is lost. Zero risk migration.

ModSecurity Compatible

ModSecurity WAF rules continue working. The OLS build includes ABI-compatible ModSecurity support, so your security rules are preserved.

Frequently Asked Questions

Everything you need to know before migrating from Apache to OpenLiteSpeed.

Yes, completely free and open source. OpenLiteSpeed is GPLv3 licensed. The installer is free to use on any number of servers with no license keys, subscription fees, or usage limits. CyberPanel provides this as a community resource.

No. The installer reads your existing Apache configuration natively and starts OpenLiteSpeed with the same settings. The transition is seamless -- Apache is stopped and OpenLiteSpeed starts on the same ports in a matter of seconds. There is no period where both are down.

Yes, one command restores Apache completely. The uninstall command is included in the installation email you receive when you register free. Your original Apache installation is restored with its original configuration intact. The original Apache binary and configs are preserved during installation.

Yes, and WordPress gets a massive performance boost. OpenLiteSpeed includes built-in LSCache support. Install the free LiteSpeed Cache plugin from the WordPress plugin directory and get instant full-page caching, image optimization, CSS/JS minification, and CDN integration -- all without any server-side configuration.

All existing SSL certificates continue working without any changes. The installer reads SSLCertificateFile and SSLCertificateKeyFile from your Apache config and applies them to OpenLiteSpeed listeners automatically. Let's Encrypt auto-renewal continues working. Combined PEM certificates (cert + key in one file) are also supported.

All PHP versions from 5.6 through 8.3+ are auto-detected from your existing Apache configuration. The installer recognizes PHP from multiple sources: cPanel ea-php handlers, CloudLinux alt-php, Plesk plesk-php, Virtualmin FCGIWrapper paths, FPM socket configurations, and AddHandler/AddType directives. Each site uses the same PHP version it was already running.
