- Irssi: Irssi is a popular open source and free text based IRC client. Irssi is different from BitchX because it does not use the old ircII code. Irssi also supports Perl scripting and runtime modules, so it is highly customizable. There are binaries available for several operating systems including Mac OSX and Windows. http://www.irssi.org
- WeeChat: WeeChat is an open source text based client with some advanced features like multiple interface capability, horizontal and vertical window splitting, nickname list, smart "hotlist" in the status bar to show channel activity by name, highlighting without switching channels, and spell checking. http://weechat.flashtux.org
- BitchX: BitchX is another popular open source text based IRC client for UNIX. It started out as a script for the ircII client, but then panasync patched the script directly into the actual client in 1994. There are binaries for many operating systems including Windows. http://www.bitchx.org
Mibbit is a popular and feature rich AJAX client which allows users to easily connect to IRC from any web browser without plugins or special firewall requirements. Webmasters can create a Mibbit Widget to embed the chat application on their website. Please note that Mibbit is an externally hosted service so we have no control over its operation or reliability, though we do recommend it for its ease of use, good interface/features, and overall stability. http://mibbit.com
MIXXnet fully supports connecting through Mibbit on all servers, and Mibbit users will have their real hostnames shown on the network. "irc.mixxnet.net" must be used in the "server" parameter to allow users' real hostnames to show up.
lightIRC is a freeware Flash IRC client with a clean and easy to use interface. Website admins can host the files on their own server or add an iframe to existing files on lightIRC's server. This client requires users to have the Adobe Flash plugin enabled in their browser which can limit compatibility as there is not official Flash support for all operating systems/browsers. http://lightirc.com
All MIXXnet servers in the main rotation have support for lightIRC, however the "policyPort" parameter must be set to "6843" for the application to properly connect.
We also recommend setting the "ident" parameter on lightIRC to the name of your channel as the default random string may cause users to be incorrectly identified as malicious bots.
