```csharp
public class BuildPipeline
```

## Remarks

The BuildPipeline class in the Unity Editor namespace provides tools to [build Players](/engine/7000.0/script-reference/unityeditor/buildpipeline/buildplayer.md) and create [content directory](/engine/7000.0/script-reference/unityeditor/buildpipeline/buildcontentdirectory.md) or [AssetBundle](/engine/7000.0/script-reference/unityeditor/buildpipeline/buildassetbundles.md) builds. AssetBundles can be loaded from external sources such as the web, enhancing the flexibility and scalability of content delivery in Unity applications. The class contains several static properties and methods to facilitate building workflows.
