# Using unmanaged API for transform operations

> Use the TransformHandle API as an alternative to the Transform API.

The [`TransformHandle`](/engine/6000.6/script-reference/unityengine/transformhandle.md) API is an alternative to the [`Transform`](/engine/6000.6/script-reference/unityengine/transform.md) API. Unlike the `Transform` component (a managed class), `TransformHandle` is an unmanaged `struct`, which makes it fully compatible with the [Burst](http://docs.unity3d.com/Packages/com.unity.burst@latest) compiler.
