Psi

Open source; $0

Current Version: 0.14 (December 3, 2009)

Psi is a free, open source Jabber client for Mac OS X. (Jabber is an open source instant messaging system fully based on XML. Thanks to the server-side Jabber Agents, Jabber clients can communicate with users of other instant messaging systems, like AIM, ICQ, Yahoo, MSN, or IRC.) Psi is small, fast and responsive. It uses a graphical toolkit called Qt, which takes on the appearance of whichever operating system you run it on. For this reason, Psi doesn't use 'skins'. We'd rather it blend with your desktop like any other application. Psi has full support for Unicode. Unicode allows Psi to send and receive messages in other languages, even ones that aren't based upon the English letterset. In fact, you are able to use Psi in your choice of eight different languages, with more on the way. Cross-platform compatibility is important to the Psi development team; they believe that you should be able to use whichever operating system you wish. In keeping with this belief, there is a version for each of the three major OS's: Microsoft Windows XP, Apple Mac OS X and GNU/Linux/KDE3.
