Anyworld: a self-hosted multiplayer text RPG with a local LLM as DM

On October 3, 2026, a developer posted on Reddit's LocalLLaMA community about a game called Anyworld that they said they have been working on. According to the post, Anyworld is a browser-based text adventure that supports multiplayer as well as single-player play, and it draws its inspiration from the early days of AI Dungeon, in particular the free browser-based version AI Dungeon 2.

The setup described in the post is straightforward. One person hosts the server and runs the model locally through llama.cpp, so a locally run LLM acts as the game master, or DM. Cloud options are available too: OpenAI or other cloud APIs can be used instead. The post notes that going through a cloud API is a better fit for non-English players. Friends join the same session through a browser link.

That is the extent of what the material covers. It identifies the developer's project, what form it takes, and its technical path of self-hosting via llama.cpp with an option to switch to cloud APIs. No launch date, version number, player counts, or pricing details appear in the post, and no reference point other than AI Dungeon 2 is mentioned. For now the story sits at the stage of an author introducing their own work to a community, with no reported follow-up yet.
