# Worlds

> Coordinate related Simulations as one environment.

A World starts named Simulations together and returns their service endpoints.
Use a World when an agent needs several systems in one environment.

## Define the members

Map each service name to a ready Simulator reference.
Continuous derives a stable member seed from the World seed and member name.

```bash theme={null}
continuous world create \
  --name support-demo \
  --member billing=<billing-simulator-ref> \
  --member support=<support-simulator-ref> \
  --seed repeatable-world
```

The result includes one endpoint for each named member.
Member Simulations keep separate state while the World coordinates their lifecycle.

## Control the World

Stop or start every member through the World.

```bash theme={null}
continuous world stop <world-id>
continuous world start <world-id>
```

Clone a World to reuse its pinned Simulator revisions with fresh member Simulations.

```bash theme={null}
continuous world create --name support-copy --from <world-id>
```

Use the [API reference](/api-reference/overview) for exact World routes and schemas.
