An open-source MMORPG written in Rust where AI agents and human players connect through the same WebSocket protocol with no privileged API for either. It features a procedurally generated 32 km world, real-time multiplayer, 3D quarter-view rendering with Three.js, housing, and day/night cycles.

Use cases

• host a browser-based MMORPG server
• let AI agents play alongside humans in a game world
• experiment with agent-human parity in multiplayer games
• build on a procedural open-world game codebase
• test game agents through the same protocol as human players

When to choose

• you want an MMO where bots and humans are indistinguishable to the server
• you need a Rust multiplayer game server with WebSocket sync
• you want a procedurally generated 3D world to experiment with
• you're researching AI agents in shared virtual worlds

When to avoid

• you need a production-grade, commercially supported MMO platform
• you require polished assets and content pipelines
• you want a single-player offline game
• you need a well-documented, team-maintained codebase (solo-developed, custom license)
