Irssi ({{IPA|fi|ˈirsːi}} {{small|([https://irssi.org/assets/irssi.wav listen])}}) is an Internet Relay Chat (IRC) client program for Linux, FreeBSD, macOS and Microsoft Windows. It was originally written by Timo Sirainen, and released under the terms of the GNU GPL-2.0-or-later in January 1999.

The program has a text-based user interface was written from scratch using C. It may be customized by editing its config files or by installing plugins and Perl scripts. Though initially developed for Unix-like operating systems, it has been successfully ported to both Windows and macOS.

Features

Irssi is written in the C programming language and in normal operation uses a text-mode user interface.{{cite web |first=Vincent |last=Danen |work=TechRepublic |date=May 5, 2008 |title=Try IRC with Irssi to communicate via chat |publisher=ZDnetAsia.com |access-date=2010-10-18 |url=http://www.zdnetasia.com/techguide/opensource/0,39044899,62040926,00.htm |archive-url=https://web.archive.org/web/20091227104809/http://www.zdnetasia.com/techguide/opensource/0,39044899,62040926,00.htm |archive-date=December 27, 2009 |url-status=dead }}

According to the developers, Irssi was written from scratch, not based on ircII (like BitchX and epic). This freed the developers from having to deal with the constraints of an existing codebase, allowing them to maintain tighter control over issues such as security and customization.{{cite web
