irssi is a mature, full-featured terminal-based IRC client for Unix/Linux systems.

Key Features

First-time Configuration

irssi works well out of the box for most users, and the defaults are generally unobtrusive to other users. Power users may find the number of window selection keybindings inadequate, but beyond that, little or no configuration is needed.



irssi can be extended by scripts written in Perl. Documentation for the script API can be found on the irssi website.

Finding scripts for irssi


irssi supports theming to customize the appearance and color scheme of the client. Themes are stored in toe client directory (~/.irssi/) and loaded with the command /SET theme theme_name

A small collection of themes can be found on the irssi website.
