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

The program has a [[text-based user interface]] was written from scratch using [[C (programming language)|C]]. It may be customized by editing its [[config files]] or by installing [[Plug-in (computing)|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)|C programming language]] and in normal operation uses a [[Text user interface|text-mode]] user interface.<ref name="Danen">{{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 }}</ref>

According to the developers, Irssi was written from scratch, not based on [[ircII]] (like [[BitchX]] and epic).<ref name="Aboutarchive"/> 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 [[computer security|security]] and customization.<ref name="Aboutarchive">{{cite web
