OpenXR™ Software Development Kit (SDK) Sources Project

This repository contains source code and build scripts for implementations of the OpenXR loader, validation layers, and code samples.

The authoritative public repository is located at It hosts the public Issue tracker, and accepts patches (Pull Requests) from the general public.

If you want to simply write an application using OpenXR (the headers and loader), with minimum dependencies, see That project is based on this one, but contains all generated files pre-generated, removing the requirement for Python or build-time file generation, and omits the samples, tests, and API layers, as they are not typically built as a part of an application.

Note about git blame

We are tracking "bulk commits" in the .git-blame-ignore-revs file, for better git blame output. Sadly it appears that web interfaces do not yet handle this file, but you can if using the command line. See --ignore-revs-file docs for details, and this blog post about ignore-revs for some useful usage details.
