What this is

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 authoritative multiplayer server, the live world you play at worldofclaudecraft.com, where Postgres-backed accounts share one persistent realm,
• the offline browser world, a local single-player Sim you get from the dev server, useful for development and for reading the game core end to end,
• the headless RL env, where Python drives the real game through a Gym interface.

Same seed, same world, everywhere. Much of what you see is still drawn from code at runtime, and the rest is a curated asset set that ships with the project, so a fork runs out of the box.
