WebVR was an experimental JavaScript application programming interface (API) that enabled applications to interact with virtual reality devices, such as the HTC Vive, Oculus Rift, Google Cardboard or Open Source Virtual Reality (OSVR) in a web browser. It was implemented in Firefox and Chromium-based browsers before being deprecated and removed. The WebVR API was superseded by a more powerful WebXR API that is capable of representing virtual reality and augmented reality devices simultaneously.
