# Run Sandboxes

> Run multiple sandboxes and stop or start containers, with dashboard and tunnel guidance where supported.

Use these workflows to keep existing sandboxes reachable and control the resources they consume.

## Run Multiple Sandboxes

Deep Agents sandboxes do not expose a dashboard port.
The first `nemo-deepagents onboard` run can use the default sandbox name from the wizard.
When you create another Deep Agents sandbox, choose a distinct sandbox name in the wizard or pass `--name` in scripted runs.

If you intentionally run separate OpenShell gateways on the same host, set a different `NEMOCLAW_GATEWAY_PORT` before each onboarding run.
NemoClaw isolates the gateway name and local state by port so one port-specific gateway does not replace another.
Gateway cleanup is scoped by sandbox name and port.

```bash
nemo-deepagents onboard
# For an additional named sandbox:
nemo-deepagents onboard --name <sandbox-name>
```

## Stop and Start a Sandbox

Stop a sandbox's container to free CPU, memory, and GPU resources without losing anything:

```bash
nemo-deepagents <sandbox-name> stop
```

Workspace files, credentials, network policies, and the registry entry are preserved; only the container stops running.

Start it again later:

```bash
nemo-deepagents <sandbox-name> start
```

NemoClaw restarts the container so the managed terminal runtime can run again.
Refer to [`nemo-deepagents <name> stop`](../../reference/commands#nemo-deepagents-name-stop) and [`nemo-deepagents <name> start`](../../reference/commands#nemo-deepagents-name-start) for details.
Use [`nemo-deepagents <name> destroy`](../../reference/commands#nemo-deepagents-name-destroy) when you want to delete the sandbox instead.
