Jabber.org is a public, free instant messaging (IM) and presence service, based on XMPP, an open standard for IM.
Jabber.org was started in 1999[1] and has offered free instant messaging continuously since.
As of 2012, it was a public production service, and one of the biggest nodes[citation needed] on the open XMPP network, with an average of 17,000 users logged in at a time.
In 2010 the service was migrated to Isode Limited's M-Link XMPP Server.
