NVIDIA unveils CloudXR.js JavaScript SDK for browser-based XR experiences

NVIDIA announced the NVIDIA CloudXR.js JavaScript SDK on March 31, 2026. The SDK lets developers stream GPU-rendered immersive content directly to standard web browsers, without app stores, installations or device-specific builds. Supported headsets are Meta Quest 2/3/3s (OS v79+) and Pico 4 Ultra (Pico OS 15.4.4U+). On the server side, it pairs with OpenXR-compatible applications and enables streaming at up to 120 fps using AV1, H.265 or H.264 encoding. WebGL and React sample clients are available, and Docker deployment is supported.

For developers creating enterprise virtual and augmented reality experiences, the key benefit is being able to reach headset users through a URL while avoiding dedicated app distribution and device-specific versions. However, use requires a supported browser and headset, an NVIDIA GPU server running an OpenXR-compatible application and CloudXR Runtime, and a fast, low-latency wireless connection, which clearly limits deployment conditions.
