# Extend Journey Builder

Journey Builder includes numerous useful out-of-the-box journey components for marketers and developers who use the Journey Builder canvas.

| Event Types | Activity Types        | Goal Types   |
| ----------- | --------------------- | ------------ |
| Event       | MultiCriteriaDecision | ContactEvent |
|             | DataExtensionUpdate   |              |
|             | Email                 |              |
|             | EngagementDecision    |              |
|             | RandomSplit           |              |
|             | Wait                  |              |

When your business needs expand beyond these components, develop custom events and activities. Marketers then use these custom activities and events on the Journey Builder canvas to extend the native capabilities.
