Google VR View for the Web is a solid choice for web sites that need an embedded 360 image. Separate SDKs are available for Android and iOS. If you’re focused on Daydream or Cardboard for a VR experience, there is a VR Entry Flow. If you’re looking for a wide market of full VR headsets, A-Frame is a better choice. You can tell your clients you’re using Google VR technology and they’ll nod their heads. Google has a significant investment in VR and 360 image technologies.

Google provides developers with two virtual reality (VR) platforms: Cardboard, the world’s most popular and accessible mobile VR platform, and Daydream, a new platform for low-latency, immersive, and interactive mobile VR. The Google VR SDKs include everything you need to develop for these platforms, including libraries, API documentation, developer samples, and design guidelines.
