Editing Ejabberd (section)

== 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,<ref>{{Cite web |url=http://www.imtrends.com/do/search_domain_simple?domain=jabber.ru&x=20&y=12 |title=online verification of jabber.ru XMPP server software |access-date=2009-12-18 |archive-url=https://web.archive.org/web/20110713022443/http://www.imtrends.com/do/search_domain_simple?domain=jabber.ru&x=20&y=12 |archive-date=2011-07-13 |url-status=dead }}</ref> that handles between 10,000 and 20,000 concurrent users at any time.<ref>{{Cite web |url=http://stats.jabber.ru/ |title=online statistics of jabber.ru XMPP server |access-date=2009-12-18 |archive-url=https://web.archive.org/web/20091217173843/http://stats.jabber.ru/ |archive-date=2009-12-17 |url-status=dead }}</ref> Among smaller XMPP-related sites, ejabberd is also the most popular server.<ref name="xmpp" /> 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%.<ref>[https://www.process-one.net/en/imtrends/article/usage_estimation_of_public_xmpp_servers_per_domain/ Usage estimation of public XMPP servers per domain]</ref>

In the [[Free and open-source software|FOSS]] world, there is a pair of notable generic deployments of ejabberd, namely the [[KDE]] Talk<ref name="kdetalk" /> and the Fellowship of the [[Free Software Foundation Europe]].<ref>[http://wiki.fsfe.org/Jabber FSFE Jabber wiki] {{webarchive|url=https://web.archive.org/web/20120222002155/http://wiki.fsfe.org/Jabber |date=2012-02-22 }}</ref><ref>{{Cite web |url=http://www.imtrends.com/do/search_domain_simple?domain=jabber.fsfe.org&x=27&y=15 |title=online verification of jabber.fsfe.org XMPP server |access-date=2009-12-17 |archive-url=https://web.archive.org/web/20110713022347/http://www.imtrends.com/do/search_domain_simple?domain=jabber.fsfe.org&x=27&y=15 |archive-date=2011-07-13 |url-status=dead }}</ref>

ejabberd chatroom feature provides the [[Internet Engineering Task Force|IETF]] Groupchat Service, used by the various working groups, areas, and BOF sessions during meetings and at other times.<ref name="ietf" /><ref name="imtrends_a" />

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.<ref name="bbc" /> sameplace.cc is a [[Firefox|Mozilla Firefox]] extension that integrates Jabber/XMPP in the web browser, and uses ejabberd for the XMPP server.<ref>[http://www.sameplace.cc/blogs/bard/2008/2/17/back-in-game Back in game] {{webarchive|url=https://web.archive.org/web/20080618222352/http://www.sameplace.cc/blogs/bard/2008/2/17/back-in-game |date=2008-06-18 }}</ref><ref>{{Cite web |url=http://www.imtrends.com/do/search_domain_simple?domain=sameplace.cc&x=0&y=0 |title=online verification of sameplace.cc XMPP server |access-date=2009-12-20 |archive-url=https://web.archive.org/web/20110713022502/http://www.imtrends.com/do/search_domain_simple?domain=sameplace.cc&x=0&y=0 |archive-date=2011-07-13 |url-status=dead }}</ref> Other deployments include Chesspark (online chess playing site),<ref>[http://metajack.wordpress.com/2008/08/26/choosing-an-xmpp-server/ Choosing An XMPP Server]</ref> [[Collecta]] (real-time search),<ref>{{Cite web |url=http://www.imtrends.com/do/search_domain_simple?domain=collecta.com&x=0&y=0 |title=online verification of XMPP server |access-date=2009-12-22 |archive-url=https://web.archive.org/web/20110713022523/http://www.imtrends.com/do/search_domain_simple?domain=collecta.com&x=0&y=0 |archive-date=2011-07-13 |url-status=dead }}</ref> and Notifixious (notifications of website subscriptions).<ref>[http://blog.notifixio.us/post/56167273/switch-from-openfire-to-ejabberd-done Switch from Openfire to Ejabberd: done!] {{webarchive|url=https://web.archive.org/web/20090423035812/http://blog.notifixio.us/post/56167273/switch-from-openfire-to-ejabberd-done |date=2009-04-23 }}</ref>

[[One Laptop per Child]]'s [[OLPC XS|School server]] uses ejabberd with OLPC-specific patches as the instant messaging server.<ref>[http://wiki.laptop.org/go/Jabber_server Run a jabber server]</ref>

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,<ref name="cufp.galois" /> 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".<ref name="gigaom" /> On Feb 10th 2010, the Facebook blog announced the opening of the XMPP interface to Facebook chat,<ref>{{cite web|url=http://blog.facebook.com/blog.php?post=297991732130 |title=Facebook Chat Now Available Everywhere &#124; Facebook |publisher=Blog.facebook.com |access-date=2012-02-10}}</ref> based on ejabberd.
