Ariadne contains all you need to make anything from a simple website, to a corporate multi language multiple site system, to complex web applications. Ariadne handles the common chores, like user management, roles and security, file management, templates, caching, multiple languages, full text searches, etc.

Ariadne isn't limited to the web, it also has support for FTP and WebDAV (both client and server), PDF, RSS, CSV, SOAP, XML-RPC, XML, LDAP and ActiveDirectory, Word and Openoffice documents, external relational databases, etc.

If what you need is not a standard part of Ariadne, it is easy to extend using its modular plugin architecture. Ariadne is built using the popular PHP language, which means that almost anything you want is probably already available somewhere for free.
