Is this really FREE, or is it a 15-day free trial?

The standard edition is free, but the enterprise edition costs money. MacUpdate keeps linking to the wrong edition. Go to the developer's web site to get the correct one.

How does this compare to WebSTAR? WebSTAR is a combo http, ftp and mail server which has served me well over the years, but I'm beginning to think that the PHP implementation in WebSTAR is a bit flaky, so I've been considering switching to something else. But Litespeed is only a web server, and does not include a mail server or ftp server, correct? Thanks!

Yes, it is only a web server. Used WebSTAR for years on OS9 and still miss many aspects including the built in FTP and the very easy to use admin program. This and Abyss are the only servers that I have used that have decent administration interfaces relative to what WebSTAR had, but they still don't match the easy and convenience of WebSTAR Admin, which was written in Java.

I can't find anything superior to the free web servers, such as Apache, nginx or lighttpd.

I've done some testing of this and so far it looks good - much more logical than Apache. I still prefer Abyss web server at this point, but I strongly recommend that you check this out.

Apache really needs some strong competition as it can be a bloated pain in the butt. LiteSpeed and Abyss can do better than Apache for most needs.
