World of Claudecraft

World of ClaudeCraft is a complete classic-era MMO you can play right now in your browser, host yourself with one command, and even train AI agents to play. It is free, open source, and live at worldofclaudecraft.com. One shared world runs in three places, all from the same game core: the offline browser world, where you click Play Offline and you are in, the authoritative multiplayer server, where Postgres-backed accounts share a live world, the headless RL env, where Python drives the real game through a Gym interface. Same seed, same world, everywhere. And almost nothing is a shipped asset: the towns, creatures, spell icons, and sound are all generated at runtime.
