The Immersive Web Emulator (IWE) is a browser extension that injects a WebXR runtime into web pages, enabling full WebXR emulation on desktop, Chromium-based browsers.
Powered by the Immersive Web Emulation Runtime, IWE offers a comprehensive WebXR runtime that polyfills or overrides existing WebXR APIs. It includes the Synthetic Environment Module (@iwer/sem) for mixed reality emulation capabilities and the DevUI (@iwer/devui) for an intuitive developer interface overlay.
IWE supports most mainstream WebXR features and APIs, offering compatibility on par with the WebXR support in the Meta Quest Browser.
