What can I do with WebAR?

A. Web-based augmented reality enables AR to work with a web browser.

It is also a valuable addition for existing web pages by helping developers ease into the AR market.

It works without the need to install an app and runs on HTML5, Android or iOS allowing easy and fast integration via JavaScript code.

For example, it can allow your customers to view your products in their chosen environment - like a new sofa in their living room.

You can also integrate WebAR SDK with your application and create countless experiences or illustrations.

These illustrations allow users to place a life-sized representation of an object simulating reality.

Once placed, the life-size object stays on the selected surface and the user is able to move it around three dimensionally.

This gives viewers a deeper understanding of the object than is possible with a 3D object.

Let your users experience augmented reality on your very own website using our WebAR SDK.

With just a few lines of code you can create several extraordinary, engaging, interactive Web AR experiences that will immerse your users and visualize your products letting them enjoy a browser-based augmented reality experience.
