WebXR is the standard for AR and VR experiences that need to be hand-built inside the browser. A custom training app, a research-style interactive scene or a game-like mechanic with hit detection: those live in WebXR territory. The trade-off is that every WebXR project is a custom development effort, with the usual cost of JavaScript work, asset pipelines, hosting, maintenance and per-browser testing.
For the typical reason a website needs AR (showing a product in the customer’s room at true scale), WebXR is the wrong tool. Apple Quick Look and Google Scene Viewer already do that job natively, reach billions of phones, and work across iOS and Android with no custom code. PausAR Viewer builds on those two paths and exposes them through one Elementor widget. There is no WebXR step to implement, no Three.js scene to maintain, no Safari iOS gap to design around. WebXR remains the answer when a project genuinely needs custom interactive 3D scene logic in the browser, but it is a development project, not a plug-and-play product AR solution.
| Property | WebXR | Quick Look / Scene Viewer |
|---|---|---|
| Use case | Custom interactive XR scenes | Native product AR placement |
| Implementation | Custom JavaScript development | Standard rel="ar" / intent URL |
| Reach on iOS | None on phones, immersive VR only on Vision Pro | Full on every recent iPhone, iPad and Vision Pro |
| Maintenance | Per project, ongoing | None, OS handles it |
No. For 'place this product in your room', Apple Quick Look on iOS and Google Scene Viewer on Android cover it natively, and PausAR Viewer exposes both through one Elementor widget. WebXR would add a custom development project without a benefit for that use case.
When the experience itself has to be custom-built: configurators with live hit detection in the room, game-like mechanics, research prototypes, or training apps with custom scene logic. WebXR is a development framework, not a turn-key product AR solution, so it is the right call only when the requirements actually need that level of custom code.
Not on iPhone or iPad: iOS Safari does not support WebXR. visionOS Safari supports immersive VR sessions but not the AR module. For iOS product AR, the native path is Apple Quick Look, which PausAR Viewer uses by default.
