Mongoose — a multiplayer text world

There's a cow
in the lab.

Explore a living text world shaped by the people in it. Meet friends and build something of your own.

You type commands. People answer. Sometimes the furniture does, too.

[glorp's Lab]
A compact, cluttered workspace.
A benchmark cow is near the north wall.

> say hello
You say, "hello."
A glimpse of the lab. The cow is really there.

A few doors to try.

  1. See who's here

    A list of connected players, plus people's homepages.

  2. Read something

    Books written here, and public mailing lists for the longer conversations.

  3. Look under the hood

    Browse objects and public MOO code. There's command help and a project task list (login required).

  4. Keep up with people elsewhere

    Use @fedi to follow and read ActivityPub and Bluesky feeds from inside Mongoose.

  3. Web client: spatial audio fixes

    2026-10-05

    Sounds that keep playing as you walk into their room carry on. They used to be cut and restarted at every doorway.
