<model-viewer> is a web component that makes rendering interactive 3D models - optionally in AR - easy to do, on as many browsers and devices as possible. <model-viewer> strives to give you great defaults for rendering quality and performance.

As new standards and APIs become available <model-viewer> will be improved to take advantage of them. If possible, fallbacks and polyfills will be supported to provide a seamless development experience.

The <model-viewer> web component can be installed from NPM:

npm install @google/model-viewer

It can also be used directly from various free CDNs such as unpkg.com:

<script type="module" src="https://unpkg.com/@google/model-viewer/dist/model-viewer.min.js"></script>

Important note about versions

Our goal for <model-viewer> is to be a consistent, stable part of your web platform while continuing to deliver cutting-edge features. We’ll always try to minimize breaking changes, and to keep the component backwards compatible. See our guide to contributing for more information on backwards compatibility.

For your production site you may want the extra stability that comes by pinning to a specific version, and upgrading on your own schedule (after testing).

If you’ve installed via NPM, you’re all set - you’ll only upgrade when you run npm update.

If you’re using unpkg.com, you can pin to a specific version by specifying it in the URL. Replace the <version> tag in the sample below with the full version number (like 0.10.0) to be pinned to.

<!-- Loads <model-viewer> for modern browsers: -->
<script type="module"
