Hi,
The one you saw on DigitalOcean Marketplace is OpenLiteSpeed, it’s a free version for everyone to use, no domain limit, no resource limit. So you don’t need to pay any for the software.
And LiteSpeed Web Server Enterprise version will need a license, which starts from $0/month with some limits (e.g. certain amount of RAM).
I hope it’s clear now.
Best, Eric
there is total 4 things you need to know
LiteSpeed , depends on context, can be referred as “LiteSpeed Cache plugin” , or “LiteSpeed WebServer” or “OpenLiteSpeed”
in above concepts , OpenLiteSpeed is total free and open sourced
while LiteSpeed WebServer (refers as Enterprise edition) has license tier, there is a free license for server less than 2GB RAM
LiteSpeed Cache plugin itself is free and open sourced , however it requires LSWS or OLS to work on caching , and page optimization (like css combine , js minify …etc) can also be working on non-LS server.
