OpenXRs

OpenXRs is an open-source software project that provides a cross-platform runtime and development toolkit designed to streamline the creation and deployment of extended reality (XR) applications. Built to complement the OpenXR standard, it aims to unify toolchains, runtime support, and content ecosystems across devices and engines.

Its scope includes a modular runtime that can interface with hardware vendors through OpenXR, a cross-platform compositor, input and gesture abstractions, and developer tools for profiling, debugging, and automated testing. The project emphasizes performance, low-latency input, and efficient resource management.

Its architecture centers on a core OpenXR-compliant runtime with a plugin system that enables backend integration for various GPUs and devices. It provides engine-agnostic bindings and optional integration layers for popular engines such as Unity and Unreal, along with a scene graph and resource pipeline abstractions. The design supports extension by modules for eye tracking, hand tracking, and foveated rendering.

OpenXRs is released under the MIT license and governed by a community council with electable maintainers and regular project reviews. Contributions are coordinated via public Git repositories, issue trackers, and continuous integration pipelines.

The project originated from an international community of researchers and developers focused on XR portability and interoperability. It has seen gradual adoption among independent studios and research labs seeking platform-agnostic XR prototyping, with ongoing work to expand hardware support and engine integrations.
