Question: Can you suggest a platform that allows developers to build augmented reality experiences for multiple devices and operating systems?

For a flexible foundation for developers to create augmented reality experiences for many devices and operating systems, Wikitude Augmented Reality is a top contender. This cross-platform AR SDK supports iOS, Android and Smart Glasses apps with features like Image Tracking, Object & Scene Tracking, Instant Tracking (SLAM) and Geo AR. It also offers Cloud Recognition, Multiple Image and Object Trackers and support for both Unity and native APIs, making it a good choice for sophisticated AR projects in retail, education and entertainment.

Another contender is Blippar, which offers a collection of tools and services for creating AR experiences without programming. Its web-based AR experience development tool, Blippbuilder Studio, offers features like 3D models, surface, marker and face tracking. Blippar also offers a WebAR SDK that works with frameworks like PlayCanvas, A-Frame and Babylon.js, as well as a Unity plug-in for integration. It's a good choice for developers who want to create sophisticated AR content but don't have a lot of technical expertise.

If you want a developer-focused foundation, EasyAR offers a modular and flexible API anchored by the Sense SDK, which integrates with Unity. EasyAR includes spatial mapping, motion tracking and image recognition features like 3D point clouds and meshes. It supports iOS, Android and MR eyewear, and includes powerful spatial map building and accurate 3D reconstruction. It's a good choice for developers who want to handle large amounts of data collection and mapping, which is why it's a good fit for AR projects in many industries.

Last, 8th Wall is a good choice for building web-based AR and 3D experiences without needing separate apps. It can be used for immersive gaming and interactive experiences through ordinary web browsers, so it's more broadly available than some other options. Among its features are support for web-based AR and 3D experiences, and examples of use in marketing, education and retail. It's a good choice for developers who want to bring AR to web-based projects without technical hassles.
