WebXR

What is WebXR?

The WebXR Device API provides access to the input and output capabilities of VR and AR hardware, including head tracking, motion controllers, hand tracking, and display output, through standard web APIs. It lets a web page detect whether XR capabilities are available, query what the device supports, poll device and input state each frame, and present imagery at the appropriate frame rate.

The “X” in XR is not part of an acronym. It is used as an algebraic variable to stand in for the many forms “_____ Reality” can take: Virtual Reality, Augmented Reality, Mixed Reality, and whatever comes next. The API is designed to cover all of them without being limited to any one.

WebXR supports three broad modes of use: inline sessions, which render XR-responsive content within a normal web page (sometimes called “Magic Window” mode); immersive-vr sessions, which present content directly to a headset; and immersive-ar sessions, which overlay content on a view of the real world.

Because WebXR content is delivered over the web, a few things follow naturally from that:

• Accessed by URL: no app store submission or installation step is involved.
• Updated in place: a change to the hosted content is immediately reflected for anyone who visits.
• Device-agnostic: the same page can run on a standalone headset, a tethered PC rig, an AR-capable phone, or an inline preview in a desktop browser.
• Hardware-independent: the API targets capabilities, not specific devices, so it continues to work as new compatible hardware appears.

Does your device support WebXR?

The results below are generated live from your current browser. Support for individual WebXR modules means the browser can expose the feature when the underlying hardware provides it.

To embed WebXR content in an iframe, add allow="xr-spatial-tracking" so the embedded page can access the WebXR Device API. This embed is the Input Selection sample from the Immersive Web Working Group.
