Browser Compatibility

WebXR has limited support at time of writing. See compatibility at caniuse or on MDN

A special build of Firefox, Fiefox Reality, has built-in support for WebXR.

The polyfill will fall back to the old WebVR API if it is available.

Polyfilled WebXR

If the user does not have supported headset, browser or device, the content will still work through the use of the WebXR Polyfill.

Mobile support

This asset works by utilizing Unity's WebGL platform support and therefore shares the same limitations. Because of this, mobile support is limited and may not work. See Unity's WebGL browser compatibility.

Developer Privacy Notice for Data Collection

Last updated: March 2018

To help improve the WebVR API and the Unity WebVR Assets package, each time a web page built using the WebVR Assets is loaded, Mozilla automatically receives general-usage statistics and uncaught JavaScript errors encountered by end-users, using Google Analytics and Sentry, respectively. The complete list of collected data includes metrics for counting the number of unique web-page sessions; time for web pages to load and time open; JavaScript error exceptions occurred on the page; the number of times a VR device is mounted and worn; number of times VR mode is enabled and time spent; and a random identifier.

You as a developer can turn off this data collection by modifying the configuration snippet that comes with the VR template. It is your obligation to inform your end-users of this data collection and to inform them that it can be turned off by enabling “Do-Not-Track” in their browsers.


This project was heavily influenced by early explorations in using Unity to build for WebVR by @gtk2k, Chris Miller (@chrmi) and Anthony Palma.

Also, thanks to Arturo Paracuellos (@arturitu) for creating the 3D-hand models used for controllers in these examples.
