DJabberd: XMPP server where everything is a plugin.
by clochix & 1 other(s)DJabberd is a high-performance, scalable, extensible Jabber/XMPP server framework. While it comes with an example server, it's really a set of classes for you to build your own Jabber server without understanding Jabber. Instead of working with XML and protocol-specific details, you subclass parts and work with sane objects and data structures and let DJabberd do all the ugly work.
