IM Clients That Support IRC

For your convience, here is a list of Instant Messaging (IM) clients that are known to support IRC.

NOTE: IM clients that only partially support the IRC protocol have been omitted from this article.

Centericq
Centericq is a text mode menu- and window-driven instant messaging interface that supports the ICQ, Yahoo!, AIM, MSN, IRC, Jabber, LiveJournal, and Gadu-Gadu protocols. It allows you to send, receive, and forward messages, URLs, SMSes (both through the ICQ server and email gateways supported by Mirabilis), contacts, and email express messages, and it has many other useful features. Known to work in Linux, FreeBSD, NetBSD, OpenBSD, Solaris, Windows and Mac OS X/Darwin Operating Systems.

Fire
Fire is the first instant messaging client for Mac OS X (previously for OPENSTEP), that can access IRC, Jabber, AIM, ICQ, MSN, Yahoo! Messenger, and Bonjour. All services are built on GPL’d libraries, including firetalk, libfaim, libicq2000, libmsn, Jabber, and libyahoo2.

On 2007-02-23 it was announced that there would be no future versions of Fire released. The official Fire website stated there were several reasons, the biggest being the loss of developers, followed by the fact that most components libraries used by Fire are no longer in active development. Two of Fire's developers have joined the Adium team and have written a transition path for users to move from Fire to Adium. The announcement also says to look to Adium for future IM needs.

Kopete
Kopete is a multi-protocol, free software instant messaging client. Although it can run in numerous environments, it was designed for and integrates with the KDE desktop environment. According to the Kopete FAQ, the name Kopete comes from the Chilean word Copete, a word to refer to alcoholic drinks.
