If you are deciding which XR runtime standard to build on, that choice has real consequences. It determines which devices your application can reach, which platform dependencies you carry, and how portable your codebase stays as hardware evolves. We evaluated both OpenXR and OpenVR across seven factors between March 2025 and May 2026. Each factor is weighted by its practical impact on enterprise and developer decisions:
Based on this framework, OpenXR ranks as the stronger standard for production enterprise use. OpenVR retains a role in legacy SteamVR-connected workflows. This article covers:
In the table below, we break down both standards across each weighted factor.

OpenXR is a royalty-free, open standard developed by the Khronos Group¹. It provides a single API that lets developers deploy XR applications across any conformant AR or VR device. No platform-specific rewrites are needed.
OpenXR was announced at GDC 2017 and released as version 1.0 in July 2019¹. Conformant runtimes now span Meta, Microsoft, HTC, PICO, Varjo, and Valve, among others². OpenXR 1.1, released in April 2024¹, consolidated multiple extensions into the core spec to reduce fragmentation further.
For developers, OpenXR defines a consistent interface between the application and the runtime. It handles tracking, frame submission, input management, and session lifecycle through a single API. This works regardless of which headset is connected¹.
Engine support is production-ready across major platforms:
Before OpenXR, targeting three headsets required three separate proprietary code paths. OpenXR replaces that fragmentation with one. Vendor-specific extensions remain available for hardware features beyond the core spec¹.
OpenVR is an open-source SDK developed by Valve Corporation³. It provides developers access to VR hardware through the SteamVR runtime and was the de facto standard for PC VR development for several years. It remains SteamVR's default runtime today.
The key distinction is not the license but the governance. While OpenVR's source code is available under a BSD-3-Clause license, it is controlled solely by Valve and tethered to the proprietary SteamVR runtime. It is not a multi-stakeholder open standard, and no industry working group governs its evolution⁴.
Where OpenVR still applies:
Where OpenVR falls short:
The right standard depends on what you are building and where you plan to run it.
Organizations deploying XR in defense, automotive, or manufacturing have requirements OpenVR was not built to serve. These include mixed headset fleets, strict data security requirements, and coverage across AR and VR devices simultaneously.
OpenXR addresses each directly. Applications built against OpenXR run on any conformant headset without modification. They do not require Steam or a consumer gaming platform to function. And because OpenXR covers AR and VR equally, a single codebase supports both fully immersive headsets and optical AR glasses in the same deployment.
For enterprise XR streaming, the standard also shapes data architecture. Hololight's platform streams only pixels from server to headset; the application executes remotely and no raw data ever reaches the device. This keeps sensitive industrial and defense data inside the customer's own infrastructure.
Hololight's streaming stack is built on its own proprietary technology, developed independently of NVIDIA CloudXR, and natively supports OpenXR across all major headsets. Genesis Design Studios integrated this approach into their standard design process. The team now visualizes photorealistic Autodesk VRED designs on Apple Vision Pro with a single click⁸.
If your application is a SteamVR-connected game, or you maintain a codebase built on OpenVR, it works. HTC Vive Tracker integration is native, and a large existing library of applications runs without changes.
Even within gaming, OpenXR can show performance advantages in demanding titles. Flight simulators and racing applications can show improved frame rates on OpenXR versus OpenVR on the same hardware. Bypassing the SteamVR middleware layer reduces overhead, though real-world results vary by configuration and headset⁴.
Any project targeting more than one headset platform should build on OpenXR. Maintaining separate code paths for SteamVR, Meta's native SDK, and Microsoft's Mixed Reality toolkit adds significant overhead. Unity and Unreal both recommend OpenXR for cross-platform XR development.
The choice between these two standards carries implications beyond the immediate runtime. Building on an open, multi-vendor standard rather than a single-vendor interface has long-term consequences for infrastructure strategy.
OpenXR's working group includes Meta, Microsoft, Google, NVIDIA, Qualcomm, Valve, HTC, PICO, and more¹. The standard evolves through industry consensus. No single vendor can change the API in ways that break existing applications. For enterprise buyers building durable XR infrastructure, that stability is a hard requirement.
As hardware diversifies, OpenXR's value as a stable abstraction layer grows. New form factors, including lighter AR glasses, next-generation standalone headsets, and 5G-connected devices, all reinforce the need for a device-agnostic runtime. Organizations building against OpenXR today are not locked to any current device generation.
Hololight's platform natively supports OpenXR. The product is based on a published Khronos Specification and is expected to pass the Khronos Conformance Process. In enterprise deployments, the standard is not a technical detail; it is the foundation the entire device strategy rests on.
The choice between OpenXR and OpenVR comes down to deployment context. OpenVR works for SteamVR-connected gaming and legacy projects. For enterprise deployments, multi-device targets, and AR-inclusive strategies, OpenXR is the architecturally sound choice. It is also the right choice for any project intended to outlast the current device generation.
