MudOS is a major family of LPMud server software, implementing its own variant of the LPC programming language.[1][2] It first came into being on February 18, 1992.[3] It pioneered important technical innovations in MUDs, including the network socket support that made InterMUD communications possible[4][5] and LPC-to-C compilation.[6] Its name reflects its focus on separation of concerns between game driver and mudlib. FluffOS is Discworld MUD's fork of MudOS.

Mudlibs written for MudOS include the Nightmare Mudlib, the Lima Mudlib, the TMI Mudlib, and the LPUniversity Mudlib.

Notable MudOS-based MUDs include Accursed Lands, Costello, Nightmare LPMud, Nuclear War MUD, and The Two Towers. Genocide was an important development testbed for MudOS from 1992 to 1994, but switched back to the main LPMud branch, citing speed concerns.[7][8] Nanvaent ran on MudOS at one time,[9] though it has since ported to FluffOS.

It is one of the most feature-rich Mud systems available, making the game seem almost like a high-level operating system of its own. You can create objects within the Mud that can directly access the Internet Protocols, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP); [...]"
