XMPP Standards Foundation

Preferred license: MIT license
The mission of the XMPP Standards Foundation (XSF) is to build an open, standardized, secure, feature-rich, widely-deployed, decentralized infrastructure for real-time communication and collaboration over the Internet. We seek to achieve that goal by developing the world's best open protocols for instant messaging, presence, and other forms of near-real-time communication, based on the IETF's Extensible Messaging and Presence Protocol (a formalization of the streaming XML protocols originally defined by the Jabber open-source community).
