InspIRCd

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.
