There are two editions of LiteSpeed Web Server:
- Enterprise Edition
Enterprise Edition is a software that is owned and needs a license. Licenses can be purchased or leased (including a free starter license) from the online store. There you can find many different licenses to adapt to different server requirements.
OpenLiteSpeed is open source. It is free to use, modify and distribute through the GPLv3 license. You can find download links and more information about OpenLiteSpeed on openlitespeed.org.
