Smuxi is a free and user-friendly IRC / Twitter / XMPP client inspired by Irssi, available for Linux, Windows and Mac OS X.
Smuxi supports nick colors which are identical across channels and networks, a Caret Mode as seen in Firefox that allows to navigate through the messages using the keyboard, theming with colors and fonts, configurable tray-icon support, optional stripping of colors and formattings and convenience features like CTCP support, channel search and nickname completion. It has a tabbed document interface, tabbed user interface, and support for multiple servers.
Smuxi 0.10 was released recently with new navigation, scripting support and enhanced Twitter. See the release note for details.
