WeeChat is a fast, light and extensible chat client. It runs on many platforms (including Linux, BSD and Mac OS). I’m using it over a year and really love that client.

WeeChat is:

  • modular: a lightweight core with plugins around
  • multi-protocols: IRC and Jabber (other soon)
  • extensible: C plugins and scripts (Perl, Python, Ruby, Lua, Tcl and Scheme)
  • free software: released under GPLv3 license
  • fully documented: user’s guide, API, FAQ,.. translated in many languages

Development is very active, and bug fixes are very fast! Now here is my quick introduction on Weechat.
