# Requirements and compatibility for URP

> Understand the compatibility of URP package versions with different Unity Editor versions, and system requirements.

This page contains information on system requirements and compatibility of this package.

## Unity Editor compatibility

Since the release of Unity 2021.1, graphics packages are [core Unity packages](/engine/6000.0/manual/packages-list/packages-all/pack-core.md).

For each release of Unity (alpha, beta, or patch release), the main Unity installer contains the up-to-date versions of the following graphics packages: SRP Core, URP, HDRP, Shader Graph, and VFX Graph. Since the release of Unity 2021.1, the Package Manager shows only the major revisions of the graphics packages (version 11.0.0 for all Unity 2021.1.x releases and version 12.0.0 for all Unity 2021.2.x releases).

You can install a different version of a graphics package from disk using the Package Manager, or by modifying the `manifest.json` file.

## Render pipeline compatibility

Projects made using URP are not compatible with the High Definition Render Pipeline (HDRP) or the Built-in Render Pipeline. Before you start development, you must decide which render pipeline to use in your Project. For information on choosing a render pipeline, refer to the [Render Pipelines](/engine/6000.0/manual/render-pipelines.md) page.

## Graphics API compatibility

URP supports the following graphics APIs:

* DirectX 11 (feature level 11\_0 and later)
* DirectX 12
* Vulkan
* Metal
* OpenGL ES 3.0 and later
* OpenGL Core
* WebGL2
* WebGPU (experimental)

## Unity Player system requirements

This package does not add any extra platform-specific requirements. General system requirements for the Unity Player apply. For more information on Unity system requirements, check the [System requirements for Unity](/engine/6000.0/manual/get-started/install-and-upgrade/getting-started-installing-unity/system-requirements.md).
