InspIRCd is a modular Internet Relay Chat (IRC) server written in C++ for Linux, BSD, Windows and Mac OS X systems which was created from scratch to be stable, modern and lightweight.

As InspIRCd is one of the few IRC servers written from scratch, it avoids a number of design flaws and performance issues that plague other more established projects, such as UnrealIRCd, while providing the same level of feature parity.

InspIRCd is one of only a few IRC servers to provide a tunable number of features through the use of an advanced but well documented module system. By keeping core functionality to a minimum we hope to increase the stability, security and speed of InspIRCd while also making it customisable to the needs of many different users.

InspIRCd was designed primarily for use on the ChatSpike IRC Network but has been released under version 2 of the GNU General Public License so that the IRC community as a whole can benefit from our work.

If you have any questions about InspIRCd then you can contact our development team by visiting the #InspIRCd channel on ChatSpike.

To begin, take a look at our installation guide followed by our configuration guide.
