Evennia is a mature, open-source framework written in Python — specifically designed to build text-based, online multiplayer games such as MUDs, MUCKs, MUSHes, MUXes, and other “MU-style” virtual worlds. Rather than prescribing a rigid game structure, Evennia gives you a bare-bones but powerful foundation: default systems handle networking, database/storage, server management, user accounts, characters, rooms, items, chat channels, and basic commands — but you define the gameplay rules, content, and game logic yourself in pure Python modules. Because you use regular Python, you get all the benefits of a modern language: familiar syntax, standard libraries, version control, and rapid iteration, rather than a custom scripting language. The framework supports both traditional MUD clients (telnet-style) and a built-in HTML5 webclient, making it accessible to users on browsers or standard clients alike.
Features
- Full framework for building text-based multiplayer games (MUD/MUX/MUSH/etc.), handling networking, storage, users, rooms, items, commands, chat, etc
- Uses standard Python modules for game logic — no custom scripting language required
- Highly flexible and game-agnostic: core does not enforce combat systems, skills, classes — you design them yourself
- Comes with default “talker-style” base world and a tutorial — enabling quick start and incremental development
- Supports traditional MUD clients (telnet) and a built-in HTML5 web client for browser-based play
- Extensive documentation, community support, and actively maintained codebase under a permissive open-source license
