Replace
Apache.
A drop-in Apache replacement and the fastest way to run PHP, WordPress and e-commerce at scale. Same configs, same .htaccess — a completely different level of performance.
One Engine. Every Workload.
LiteSpeed serves cache hits and static files directly, while LSAPI connects dynamic requests to your applications.
Everything Under One Engine

Caching That Understands Your App
LSCache lives inside the web server, not in front of it. Pages are served straight from memory with tag-based purging, so logged-in users, carts and personalised blocks stay correct.
- Tag-based purge — update one post, not the whole cache
- ESI hole-punching for private, dynamic blocks
- Image optimisation, WebP and critical CSS via QUIC.cloud
- Separate mobile and desktop views automatically
Live In Five Minutes.
One command detects your control panel, imports your Apache configuration and switches the engine. Want to roll back? That's one command too.
