WeeChat (Wee Enhanced Environment for Chat) is a free and open-source Internet Relay Chat client, which is designed to be light and fast. It is released under the terms of the GNU General Public License 3 and has been developed since 2003.
In WeeChat everything can be done with a keyboard, though it also supports mouse. It is customizable and extensible with plugins and scripts.
WeeChat's features include: 
- proxy connections
- The screen can be split up to display multiple windows at the same time.
- incremental text search
- aspell support for spell checking
- scripting support for many languages (Perl, Python, Ruby, Lua, Tcl, Scheme with GNU Guile)
- FIFO pipes for remote control
- support for multiple character encodings
- user-defined aliases and shortkeys
WeeChat supports a wide variety of platforms and operating systems, including Linux, BSD derivatives (FreeBSD, NetBSD, OpenBSD, Debian GNU/kFreeBSD), Mac OS X, Debian GNU/Hurd, HP-UX, Solaris, QNX, Haiku, and Microsoft Windows (via the Cygwin library and API).
Ready-to-use packages and builds of WeeChat are available for a variety of platforms and operating systems. It is also packaged for many Linux distributions, including Debian, Ubuntu, Mandriva Linux, Fedora, Gentoo, and Arch Linux. WeeChat is also available to FreeBSD users via the FreeBSD Ports system.
In his review for Free Software Magazine, Martin Brown graded WeeChat with 43 points out of a possible 50, noting that "At first glance, WeeChat is not as friendly or easy to use as Rhapsody", but, "There’s a lot of hidden power built into the application", including Python, Perl, Ruby and Lua extensions which can be selected at installation.
