irssi
Terminal-based IRC client with modular architecture and support for multiple chat protocols
Irssi is a terminal-based chat client primarily designed for IRC communication. It operates entirely in text mode, making it suitable for server environments and users who prefer command-line interfaces. The client features a modular architecture that allows extension through third-party protocol modules, supporting ICB, SILC, XMPP (Jabber), PSYC, and Quassel protocols beyond its built-in IRC functionality.
The application provides extensive customization through themes and scripts, with dedicated repositories for both. Users can modify the interface appearance and extend functionality through Perl scripting support. Irssi includes comprehensive built-in help accessible via the /HELP command, covering all command syntax and features.
Built on glib-2.32 and requiring OpenSSL for secure connections, Irssi targets users who need persistent IRC connections, server administrators, and developers who prefer terminal-based tools. The client's stability and scriptability make it particularly useful for automated tasks, logging, and situations where a GUI client would be impractical.
