Ejabberd - Notable Deployments

Notable Deployments

ejabberd is known to be used by XMPP-related sites and a number of companies, either for providing an XMPP instant messaging service, as a meeting chat room service, or as middleware for other software (usually by means of the Publish-Subscribe service).

XMPP servers deployed for XMPP-related sites are usually run using ejabberd, both in case of large and small servers. One large public XMPP servers runs ejabberd: the Russian jabber.ru, that handles between 10,000 and 20,000 concurrent users at any time. Among smaller XMPP-related sites, ejabberd is also the most popular server. When not taking into account the size or nature of the server, ejabberd is also the most widely deployed: according to IMtrends report from July 2008 based in automated server detection, 37% of 7292 servers were running ejabberd; the second position being jabberd14 with 22.4% and the third Openfire with 18.4%.

Among generic instant messaging deployments are ISPs like the Portuguese SAPO, and the German United Internet for services like GMX and Web.de. The Russian search engine Yandex uses a highly modified version of ejabberd, conveniently named Yabberd. Nokia's Ovi uses ejabberd with some customizations. Major League Baseball offers instant messaging and chatrooms using a customized ejabberd. Mxit was a large server for mobile instant messaging client that started using ejabberd in 2005, but was replaced with a custom IM engine. Universities known to use ejabberd include: Saint Petersburg State University, Taganrog State University and the Division of Information Technology of the University of Wisconsin–Madison.

In the FOSS world, there is a pair of notable generic deployments of ejabberd, namely the KDE Talk and the Fellowship of the Free Software Foundation Europe.

ejabberd chatroom feature provides the IETF Groupchat Service, used by the various working groups, areas, and BOF sessions during meetings and at other times.

Other deployments use ejabberd in more novel ways. For instance, BBC Radio LiveText uses ejabberd's Publish-Subscribe service to synchronously broadcast text content with the radio stream. sameplace.cc is a Mozilla Firefox extension that integrates Jabber/XMPP in the web browser, and uses ejabberd for the XMPP server. Other deployments include Chesspark (online chess playing site), Collecta (real-time search), and Notifixious (notifications of website subscriptions).

One Laptop per Child's School server uses ejabberd with OLPC-specific patches as the instant messaging server.

In 2008 Facebook announced that they will support XMPP for their chat service. Facebook developers made a presentation on the topic at Commercial Users of Functional Programming (CUFP) 2009 conference, and in November 2009 chat.facebook.com was detected as running a modified version of ejabberd. Om Malik commented on the development as "disruptive" competition for "older IM networks such as AOL’s AIM and Microsoft’s MSN". On Feb 10th 2010, the Facebook blog announced the opening of the XMPP interface to Facebook chat, based on ejabberd.

Another social media and blogging service that uses ejabberd is LiveJournal Talk. The Spanish-focused Tuenti social network uses a modified ejabberd to provide a live chat service.

The worldwide jabber.org XMPP server, with a userbase of 330,000 users and 15,000 users online at any one time in December 2009, used ejabberd since February 2006 until January 2010.
