Ariadne's modular design makes it easy to extend for almost any purpose. The unique structured object store allows you to store any kind of content, while still giving you the speed of SQL.
You are not limited to websites, Ariadne has no problem serving as a SOAP, XML-RPC, FTP or WebDAV server. You can not only create html pages, but also PDF, XML, RSS and many more. Ariadne won't generate output by itself, it is all under your control.
Need to connect to other systems? No problem, Ariadne can read other websites, connect to FTP and WebDAV servers, or to SOAP and XML-RPC servers. Finally Ariadne can connect to virtually every database system there is.
