| `closeAutomatically`      | boolean | `true`                        | Clean up the session when the workflow succeeds or fails.                          |
| `keepOpenAfterManualTest` | boolean | `false`                       | Keep a manually tested session open for inspection.                                |
| `maximumDurationMs`       | number  | `1800000`                     | Maximum managed browser session duration.                                          |

<Note>Sessions are cleaned up after success or failure when `closeAutomatically` is enabled.</Note>

## Workflow JSON

The editor stores this node with the following implemented default configuration:

```json title="Default node configuration" theme={"system"}
{
  "type": "open_browser",
  "version": 1,
  "configuration": {
    "profileId": "",
    "headed": true,
    "initialUrl": "",
    "viewport": {
      "width": 1280,
      "height": 800
    },
    "defaultTimeoutMs": 30000,
    "closeAutomatically": true,
    "keepOpenAfterManualTest": false,
    "maximumDurationMs": 1800000
  }
}
```

Values may be entered literally or mapped from an earlier compatible output when the inspector exposes a mapping control. See [Variables and data mapping](/workflows/variables-and-data).

## Inputs

* Managed browser worker

## Test and inspect

Use **Test node** in the editor to preview this step with the current configuration. A full run records resolved inputs, outputs, logs, duration, and any artifacts in the execution inspector. Side-effecting or destructive nodes can require an additional confirmation or approved workflow permission.
