MudOS

MudOS is a popular multi-user dungeon (MUD) server software. It was originally developed by Stephen White and is known for its efficiency and flexibility in creating and hosting MUDs. MudOS is written primarily in C and uses its own object-oriented scripting language, often referred to as the "MudOS driver" or "MudOS LPC" (Lars Pensjö C, though the LPC language itself evolved significantly from its origins).

The core of MudOS is its driver, which handles network connections, the game loop, and the execution of object code. This object code, written in LPC, defines the game world, its inhabitants, and player interactions. MudOS supports features such as asynchronous I/O, virtual object systems, and a robust security model, making it a powerful platform for complex MUD development. Many popular MUDs, especially in the 1990s and early 2000s, were built using MudOS or its derivatives. While newer MUD server software exists, MudOS remains a significant piece of MUD history and is still used by some active MUD communities. Its architecture allows for extensive customization and the creation of unique gameplay experiences.
