Xitami
Xitami is a Web and FTP server, originally developed by iMatix Corporation as a free, open-source product from 1996 to 2000. It ran as a single process with a small footprint. It was not as fast as the fastest servers but scaled well. It supported several web application protocols and was very portable. It also had a web interface to configure the web/FTP server.
In 2009, iMatix launched a new version of Xitami, called X5 (Xitami/5).
