Heard From The Server Room

★★★★★

“We moved 1,200 cPanel accounts to LiteSpeed over a weekend. Load average dropped from 18 to 3 and support tickets about slow sites basically vanished.”

RPRizky PratamaCTO, Nusantara Hosting
★★★★★

“The Web ADC in front of our WooCommerce cluster serves 90% of traffic straight from edge cache. Flash sales are boring now — in the best way.”

AHAmelia HartHead of Infrastructure, ShopLane
★★★★★

“Licensing through LiteSpeedCore was instant, and their team helped us tune LSCache over SSH on day one. Truly white-glove.”

FAQ

Questions, Answered

Do I need to change my websites to switch from Apache?

No. LiteSpeed Web Server reads Apache configuration and .htaccess files directly, including mod_rewrite. Most migrations are a one-command switch from your control panel or SSH.

What is the difference between Web Server and Web ADC?

LiteSpeed Web Server runs on each machine that hosts your sites. LiteSpeed Web ADC sits in front of several servers as a load balancer, TLS terminator and edge cache — ideal when one server is no longer enough.

How fast is license delivery?

Instantly. Your serial key is issued as soon as payment clears and can be activated over SSH with a single command.

Can I move my license to a new server?

Yes. Release the license from the old server, then activate it on the new one. Our team can do it for you if you prefer.

Is there a trial?

Every paid edition includes a 15-day trial, and the Free Starter edition never expires for single-domain use.
