Unity supports OpenXR.

Windows supports OpenXR by way of SteamVR. SteamVR is the standard OpenXR runtime on Windows as of 2024.

Linux supports OpenXR through Monado.

OpenXR is a standard for access to virtual reality and augmented reality platforms and devices.[3] It is developed by a working group managed by the Khronos Group consortium. OpenXR was announced by the Khronos Group on February 27, 2017, during GDC 2017.[4][5][6] A provisional version of the standard was released on March 18, 2019, to enable developers and implementers to provide feedback on it.[3] On July 29, 2019, OpenXR 1.0 was released to the public by Khronos Group at SIGGRAPH 2019[7] and on April 15, 2024, OpenXR 1.1 was released by Khronos.[8]

Reviewers of the 0.90 provisional release considered that the aim of OpenXR was to "Solve AR/VR Fragmentation".[9]

Architecture

OpenXR provides an API aimed for application developers targeting virtual reality or augmented reality devices. This enables developers to build applications that work across a variety of devices, such as VR headsets.[10]

Implementations

The Khronos Group maintains the list of OpenXR-conformant platforms and products.[11]

OpenXR platforms include:

Game and rendering engine support

Support for OpenXR application development can be found in the following engines:

Browser support

Roadmap

After the release of OpenXR 1.0, progress will likely be driven through the development of extensions to the core API.[30] This can be seen in the subsequent release of extensions for support of hand tracking and eye gaze tracking.[31] As implementers and developers get more experience with the extensions, they could get integrated into the core OpenXR API in future releases.
