Prosody (software)

Prosody (formerly lxmppd ) is a cross-platform XMPP server written in Lua. Its development goals include low resource usage, ease of use, and extensibility. Prosody uses the default XMPP ports, 5222 and 5269, for client-to-server and server-to-server communications respectively.

History
Prosody development was started by Matthew Wild in August 2008 and its first release, 0.1.0, was made in December 2008.

Prosody was initially licensed under the GNU General Public License (version 2), but later switched to the MIT License in its 3rd release.
