Top Recommended Replacements
OpenLiteSpeed (OLS)
FREETop Professional Free Alternative
Why we like it
100% free; same high-performance event-driven core as Enterprise; includes LSCache; unlimited worker processes; perfect for high-traffic standalone sites.
Keep in mind
Does not automatically read .htaccess files (requires server restart to apply changes); lacks native cPanel/Plesk integration for shared hosting.
Nginx (Engine X)
FREEBest for Scalable Microservices
Why we like it
The global industry standard; extremely low memory footprint; handles 10,000+ simultaneous connections with ease; ideal for reverse-proxying and static content delivery.
Keep in mind
Lacks the 'drop-in' Apache compatibility of LiteSpeed; requires manual configuration for WordPress caching (FastCGI) compared to the automated LSCache plugin.
Caddy 2
FREEBest for Modern Ease-of-Use
Why we like it
Automated HTTPS by default via Let's Encrypt; written in Go (memory safe); modern config syntax; incredibly easy to set up for personal blogs and dev environments.
Keep in mind
Lacks the specialized PHP performance optimizations (LSAPI) found in LiteSpeed; smaller ecosystem of expert tutorials for hosting providers.
Apache (with Event MPM)
FREEBest for Legacy Flexibility
Why we like it
The most widely supported server in history; total flexibility via .htaccess; the 'Standard' choice for almost every web app; zero cost.
Keep in mind
Higher resource consumption under extreme traffic spikes compared to the event-driven models of Nginx and LiteSpeed.
