OpenXR is a royalty-free, open standard that provides high-performance access to Augmented Reality (AR) and Virtual Reality (VR)—collectively known as XR—platforms and devices.
“OpenXR seeks to simplify AR/VR software development, enabling applications to reach a wider array of hardware platforms without having to port or re-write their code and subsequently allowing platform vendors supporting OpenXR access to more applications. With the release of the OpenXR 1.0 specification, AR/VR developers can now create true cross-platform XR experiences.”
More runtimes to follow soon!
The OpenXR 1.0 specification is free for anyone to download, review and comment – please give us feedback on the specification and implementations on the Khronos OpenXR Forums, Slack Channel or Issue Tracker! If you are developing OpenXR-related resources – let us know! If you want to participate directly in the development of the OpenXR standard join Khronos and become a member of the OpenXR Working Group, please visit our Membership page.
OpenXR provides cross-platform, high-performance access directly into diverse XR device runtimes across multiple platforms. OpenXR enables applications and engines, including WebXR, to run on any system that exposes the OpenXR APIs.

“The time to embrace OpenXR is now. In the year since the industry came together to publish the OpenXR 1.0 spec and demonstrated working bits at SIGGRAPH 2019, so much progress has happened. Seeing the core platforms in our industry getting behind the standard and shipping real, conformant implementations, as well as coming together to push the spec forward with cross-vendor extensions for critical features like hand tracking and eye tracking, is singularly awesome. As for the Mixed Reality platform we build at Microsoft, the base specification plus these extensions allow us to ship a conformant OpenXR 1.0 implementation to all Windows Mixed Reality and HoloLens 2 users that provides complete access to the functionality of the products. No compromise. And on the content side, the adoption of OpenXR in Minecraft’s desktop VR product further reinforces Microsoft’s commitment to the success of OpenXR.”
