Question: Do you know of a solution that allows developers to build and publish web-based AR and 3D experiences without requiring extensive programming knowledge?

8th Wall is a collaborative environment for building and publishing web-based augmented reality (WebXR) and 3D experiences. It can be used for a variety of use cases like gaming, e-commerce and entertainment, all through ordinary web browsers, not separate apps. It's geared for marketing, education and retail, so you can easily add AR to web projects without a lot of technical expertise.

Another option is Blippar, which has a drag-and-drop interface to create AR content without programming. Its Blippbuilder Studio offers tools for surface, marker and face tracking, along with real-time feedback and iteration tools. For more sophisticated AR content, Blippar also offers a WebAR SDK that works with frameworks like A-Frame and Babylon.js, so it's a good option for developers.

Last, Snap AR is a powerful tool for creating augmented reality experiences on Snapchat, Snap Camera and Spectacles. It includes tools like Lens Studio for building AR experiences, Lens Web Builder for non-coders, and Lens Analytics for tracking engagement. Snap AR is good for creators who want to build a variety of AR experiences, with support programs and tools to help you get people to try it and to monetize it.
