SleekXMPP is a flexible XMPP client/component/server library for Python 2.6+ and 3+ focused on flexibility, ease of use, and every XMPP extension (XEP) as a plugin.
SleekXMPP is featured in O’Reilly’s XMPP: The Definitive Guide by Peter Saint-Andre, Kevin Smith, and Remko Tronçon and was used for all of the code examples. As SleekXMPP's API has had major revisions since 0.2.1 as featured in the book, please read the transition docs.
