WebXR

WebXR is the W3C standard for delivering high-performance VR and AR experiences directly through a web browser.

WebXR replaces the legacy WebVR API to provide a unified framework for immersive hardware like the Meta Quest 3, Apple Vision Pro, and Magic Leap 2. By leveraging WebGL or WebGPU, developers build spatial applications using frameworks like Three.js or A-Frame that run on a single URL without app store gatekeepers. This API handles the heavy lifting of head tracking, controller input, and floor-level sensing (spatial anchors) to ensure sub-millisecond latency across diverse mobile and desktop ecosystems.
