climm (previously mICQ) is a free text-based instant messaging client that runs on a wide variety of platforms, including AmigaOS, BeOS, Windows (using either Cygwin or MinGW), Mac OS X, NetBSD/OpenBSD/FreeBSD, Linux, Solaris, HP-UX, and AIX.

climm has many of the features the official ICQ client has, and more:

• It has support for SSL-encrypted direct connection compatible with licq and SIM.
• It supports OTR encrypted messages.
• It is internationalized; German, English, and other translations are available, and it supports sending and receiving acknowledged and non-acknowledged Unicode-encoded messages (it even understands UTF-8 messages for message types the ICQ protocol does not use them for).
• It is capable of running several UINs at the same time and is very configurable (e.g. different colors for incoming messages from different contacts or for different accounts).
• Due to its command line interface, it has good usability for blind users through text-to-speech interfaces or Braille devices.

climm also supports basic functionality of the XMPP protocol.

climm is licensed under the terms of version 2 of the GNU General Public License, and it was recently relicensed to include the OpenSSL exception. Versions prior to mICQ 0.4.8 were released by Matt D. Smith into the public domain; however, not much of the original code remains. All later additions were by Rüdiger Kuhlmann; in particular, the support for the current ICQ v8 protocol.

mICQ was renamed to climm with version change to 0.6. climm stands for "Command Line Interface Multi Messenger".
