About UnrealIRCd

UnrealIRCd is an Open Source IRC Server, serving thousands of networks since 1999. It runs on Linux, OS X and Windows and is currently the most widely deployed IRCd with a market share of 37%. UnrealIRCd is a highly advanced IRCd with a strong focus on modularity and security. It uses an advanced and highly configurable configuration file. Other key features include: full IRCv3 support, SSL/TLS, cloaking, JSON-RPC, advanced anti-flood and anti-spam systems, GeoIP, remote includes, and lots of other features. We are also particularly proud on our extensive online documentation.

Supported systems

We try to support all major *NIX systems: all Linux distros but also NetBSD, OpenBSD and macOS, provided the OS version was released within the past ~5 years.

We use a private BuildBot instance to test each commit. The tested systems are (others are likely to work too):

• Linux: Debian (10, 11, 12, 13), Ubuntu (18.04, 20.04, 22.04, 24.04, 26.04)
• FreeBSD: 15
• Windows: Visual Studio 2019

UnrealIRCd is architecture-agnostic. Most of the BuildBot workers run on x64 but we also have some on x86 and arm64 to ensure these work as well.
