**Node type:** `condition` · **Version:** `1` · **Category:** Logic

Follow a true or false branch. This node does not declare an external side effect.

## Configuration

| Field      | Type   | Default    | What it controls                                                                                                                                                   |
| ---------- | ------ | ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `left`     | string | `""`       | Value or mapped output on the left side of the comparison.                                                                                                         |
| `operator` | string | `"equals"` | Comparison operation. Values: `equals`, `not_equals`, `contains`, `not_contains`, `greater_than`, `less_than`, `exists`, `not_exists`, `starts_with`, `ends_with`. |
| `right`    | string | `""`       | Comparison value; hidden for `exists` and `not_exists`.                                                                                                            |

## Workflow JSON

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

```json title="Default node configuration" theme={"system"}
{
  "type": "condition",
  "version": 1,
  "configuration": {
    "left": "",
    "operator": "equals",
    "right": ""
  }
}
```

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

| Port    | Type  | Required | Description  |
| ------- | ----- | -------- | ------------ |
| `left`  | `any` | Yes      | Value        |
| `right` | `any` | No       | Compare with |

## Outputs

| Port     | Type      | Required | Description |
| -------- | --------- | -------- | ----------- |
| `result` | `boolean` | No       | Result      |

## Where it can run

* Desktop local runner
* Paired self-hosted runner
* Hosted runner

## 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.
