# Overview

Do you have trouble getting your hands on a VR headset? Or do you want your friends to try out your VR experience without them having to go buy themselves one? Then WebXR is the most accessible and platform-wide solution to bring phone users, desktop users, and VR users into one place!

This technology does not require a VR headset, instead it gives users the option to try what they have such as using their web browser to experience a virtual environment of a historical site. This is great for user's portfolios and demonstrations.
