CoffeeMud is a text-based fantasy Virtual Reality engine (a MUD). It is a mature, full-featured Java codebase. It includes web (HTTP) and email (SMTP) servers, chat (IMC2 and I3) and web clients, and supports ANSI, MXP, and MSP.

A MUD Engine, also called a MUD Codebase, provides the gathering place for players all over the internet to congregate for the purpose of adventuring. The person who downloads, installs, and runs the CoffeeMud server is providing his computer as a host to the fantasy world in which the players reside and pursue their adventures. This means that the host must take the time to provide such a world for the players to wander around in. CoffeeMud contains software which provides both the foundation and the tools with which the host can create such a world.

CoffeeMud is written in 100% Java, listening as a server on any specified port(s). Built-in web servers can be activated to listen on specified ports. CoffeeMud supports any JDBC/ODBC database and has been successfully tested using MySQL, HSQLDB, and Derby over JDBC, and Access/SQL Server over ODBC. The package also includes a flat-file JDBC system for beginners.

The system includes an API that allows standard MOBs, Items, Weapons, Armor, Room types, Exit types, and Magic Items to be coded in less than a hundred lines using a template. Generic MOBS, Items, Weapons, Armor, and Exit types can be be molded to fit any design and spec. And all of it can be implemented online at run-time.
