The SeaMonkey project is a community effort to develop an all-in-one Internet application suite. It contains an Internet browser, email and newsgroup client with an included Web feed reader, HTML editor, IRC chat, and Web development tools, and is sure to appeal to advanced users, Web developers, and corporate users. It uses much of the Mozilla source code powering such successful siblings as Firefox, Thunderbird, Camino, Sunbird, and Miro.
centericq is a text mode menu- and window-driven IM interface that supports the ICQ2000, Yahoo!, AIM, IRC, MSN, Gadu-Gadu, and Jabber protocols. It allows you to send, receive, and forward messages, URLs, SMSes (both through the ICQ server and email gateways supported by Mirabilis), contacts, and email express messages, and it has many other useful features. An internal RSS reader and a LiveJournal client are also provided.
BitlBee allows users to talk to people on the major instant messaging and microblogging networks (including MSN, Google Talk, AIM, and Twitter) from within any IRC client by emulating an IRC server. Virtual channels are created with all of the user's contacts in them, who can be talked to in the channel or in a query. Also, one can participate in group chats and chat rooms like they were normal IRC channels.
BitchX is the premiere IRC (Internet Relay Chat) client. It originally was a modified version of the popular ircII client, and the features were eventually merged into the EPIC IRC client. The current development is aimed at merging the client back to a current branch of EPIC and bringing compatibility and stability back to the client, while bringing the features that are BitchX into a new client.
ngIRCd is a portable IRC daemon written from scratch. It is easy to configure, supports server links (even with original ircds) and runs on hosts with changing IP addresses (such as dial-in networks). Currently supported platforms are AIX, A/UX, Darwin/Mac OS X, FreeBSD, HP-UX, IRIX, Linux, NetBSD, SunOS/Solaris, and Windows with Cygwin.
dircproxy is an IRC proxy server ("bouncer") designed for people who use IRC from lots of different workstations or clients, but wish to remain connected and see what they missed while they were away. You connect to IRC through dircproxy, and it keeps you connected to the server, even after you detach your client from it. While you're detached, it logs channel and private messages as well as important events, and when you reattach it'll download those logs to you using ordinary IRC protocol.
The Bahamut IRCD is based on the EFNet Hybrid IRCD and has many additional features primarily designed for the DALnet IRC network. Its features include very high performance, compatibility with Solaris, BSD and Linux and a high level of stability under very high load, as well as many improvements over the original EFNet code. Bahamut is not compatible with Dreamforge as of version 1.2.0.
SecureServ is an IRC trojan detector. It's much like a virus scanner, but aimed at IRC networks. Using several methods, including version checks, behavior analysis, and general pattern matching, it aims to detect trojans, viruses, and floodbots which connect to your IRC network. Its "brains" are based on a "Definition file" which contains information on how to detect trojans. To update detection for new trojans, you only have to download a new file.
CWirc is a plugin for the X-Chat IRC client to transmit raw Morse code over the internet using IRC servers as reflectors. The transmitted Morse code can be received in near real-time by other X-Chat clients with the CWirc plugin. CWirc tries to emulate a standard amateur radio rig: it sends and receives Morse over virtual channels, and it can listen to multiple senders transmitting on the same channel. Morse code is keyed locally using a straight or iambic key connected to a serial port, or using the mouse buttons, and the sound is played through the sound card, or through an external sounder.
