InspIRCd is a modular C++ IRCd (IRC daemon) for Linux, BSD, Windows and Apple OS X systems created to provide a stable, modern, and lightweight IRCd written from scratch. As InspIRCd is one of the few IRCd projects written from scratch, it avoids a number of design flaws and speed issues that plague other more established IRCd projects with the same or less features, such as UnrealIRCd 3. InspIRCd is one of the few IRCd projects to provide a vast number of features in the form of modules through the use of an advanced, well documented module API. By keeping the functionality of the main core to a minimum we hope to increase the stability and speed of our IRCd project and make it customisable to the needs of many users. InspIRCd is designed primarily to be a custom IRCd for the ChatSpike IRC network however we are releasing this free IRCd to the public under the GNU GPL so that you may benefit yourself from our work. If you have any questions about InspIRCd, or feature requests, patches etc, you may contact our development team by connecting to our IRC support channel at irc.inspircd.org.
