CI Code coverage

WeeChat (Wee Enhanced Environment for Chat) is a free chat client, fast and light, designed for many operating systems. It is highly customizable and extensible with scripts.


  • Modular chat client: WeeChat has a lightweight core and optional plugins. All plugins (including IRC) are independent and can be unloaded.

  • Multi-platform: WeeChat runs on GNU/Linux, *BSD, GNU/Hurd, Haiku, macOS and Windows (Bash/Ubuntu and Cygwin).

  • Multi-protocols: WeeChat is designed to support multiple protocols by plugins, like IRC.

  • Standards-compliant: the IRC plugin is compliant with RFCs 1459, 2810, 2811, 2812, and 2813.

  • Small, fast, and very light: the core is and should stay as light and fast as possible.

  • Customizable and extensible: there are a lot of options to customize WeeChat, and it is extensible with C plugins and scripts (Perl, Python, Ruby, Lua, Tcl, Scheme, JavaScript and PHP).

  • Fully documented: there is comprehensive documentation, which is translated into several languages.

  • Developed from scratch: WeeChat was built from scratch and is not based on any other client.

  • Free software: WeeChat is released under GPLv3.
