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.

What's new

  1. MUD areas: big worlds load in seconds

    2026-10-11

    Loading a MUD area into a world that already held several large areas could stall and leave the area half built. Each exit and detail now keeps its own record, so a 200-room area loads in a few seconds however much the world already holds.

  2. Server upgraded

    2026-10-10

    The game server was rebuilt and restarted at 23:44 UTC on 10 October (about eight seconds of downtime).

  3. Crafting, materials and plants

    2026-10-10

    Benches and forges: 'patterns' now shows the quality range your skill can reach for each pattern; skill shortens the work and raises workmanship, and workmanship changes how tough the finished item is.
