## Managing the local server

Use `yarn twenty server` to control the local Twenty container:

| Command | What it does |
|---------|--------------|
| `yarn twenty server start` | Start the server (pulls the image if needed) |
| `yarn twenty server start --port 3030` | Start on a custom port |
| `yarn twenty server stop` | Stop the server (preserves data) |
| `yarn twenty server status` | Show URL, version, and login credentials |
| `yarn twenty server logs` | Stream server logs |
| `yarn twenty server reset` | Wipe data and start fresh |
| `yarn twenty server upgrade` | Pull the latest `twenty-app-dev` image |
| `yarn twenty server upgrade 2.2.0` | Upgrade to a specific version |

Data persists across restarts in two Docker volumes (`twenty-app-dev-data` for PostgreSQL, `twenty-app-dev-storage` for files). Use `reset` to wipe everything.

## Upgrading the server image

`yarn twenty server upgrade` pulls the latest image, compares digests, and only recreates the container if anything actually changed. Volumes are preserved — only the container is replaced. If a new image was pulled and the container was running, the upgrade automatically starts a new container; run `yarn twenty server start` afterward to wait for it to become healthy.

```bash filename="Terminal"
yarn twenty server upgrade            # Latest
yarn twenty server upgrade 2.2.0      # Specific version
```

Verify the running version with `yarn twenty server status` (it shows the `APP_VERSION` baked into the container).

## Running a parallel test instance

Pass `--test` to any `server` command to manage a second, fully isolated instance — useful for integration tests or experiments without touching your main dev data:

| Command | What it does |
|---------|--------------|
| `yarn twenty server start --test` | Start the test instance (defaults to port 2021) |
| `yarn twenty server stop --test` | Stop it |
| `yarn twenty server status --test` | Show its status |
| `yarn twenty server logs --test` | Stream its logs |
| `yarn twenty server reset --test` | Wipe its data |
| `yarn twenty server upgrade --test` | Upgrade its image |

The test instance has its own container (`twenty-app-dev-test`), volumes (`twenty-app-dev-test-data`, `twenty-app-dev-test-storage`), and config — it runs alongside your main instance without conflicts. Combine `--test` with `--port` to override 2021.

## Manual setup (without the scaffolder)

Skip the scaffolder if you're adding the SDK to an existing project:

```bash filename="Terminal"
yarn add twenty-sdk twenty-client-sdk
```

Add the script to `package.json`:

```json filename="package.json"
{
  "scripts": {
    "twenty": "twenty"
  }
}
```

You can now run `yarn twenty dev`, `yarn twenty server start`, and the rest.

<Note>
Don't install `twenty-sdk` globally — pin it per project so each app uses its own version.
