I used XMPP4R to do some stats about Jabber clients usage on the Apinc Jabber server, which hosts im.apinc.org, jabber.fr, and many more using virtual hosting.

The stats were done by sending jabber:iq:version requests to online users, and 651 replies were received. It was done at 6:30 PM, french local time. Here are the results :

Systems :

• GNU/Linux : 34% (226)
• Windows: 34% (223)
• MacOS : 23% (150)
• Others (AmigaOS, FreeBSD, NetBSD, OpenBSD, SunOS) : 1% (7)
• Unknown (Gaim doesn’t always report the sytem) : 6% (45)

Clients :

• Psi : 28% (186)
• gaim : 25% (166)
• iChatAgent : 18% (121)
• Kopete : 7% (46)
• libgaim : 3% (23)
• Gajim : 3% (23)
• Pandion : 2% (18)
• Trillian : 2% (16)
• Miranda : 1% (13)
• neos : 1% (10)
• Exodus : 1% (8)
• BitlBee : 0% (6)
• Tkabber : 0% (4)
• Imendio Gossip : 0% (3)
• JAJC : 0% (2)
• webjabber.net : 0% (2)
• Gabber : 0% (1)
• Jabberwocky : 0% (1)
• Mafia : 0% (1)
• JETI : 0% (1)

The results might be biased by the facts that :

• Most of the users are quite new to Jabber
• There’s a high percentage of Mac users (and therefore iChat users) since an article was published about Jabber on a popular french Mac website. Those users are sort of parasites who only use the MSN transport.

The script to do the mass-jabber:iq:version sending is available in the XMPP4R SVN repository (data/doc/xmpp4r/examples/advanced/versionpoll.rb). The ruby script to analyze results can be sent on demand. So please run the scripts on your servers :-)
