AR.js Studio vs Reality Composer

AR.js Studio is a free, open-source web authoring platform for building augmented reality experiences without coding. It supports location-based projects, which place AR content at GPS coordinates, and marker-based projects, which anchor content to a black-and-white visual marker. Location projects can use a dropped pin or entered coordinates for up to 10 locations. Marker projects can use a premade marker or an uploaded image; simple, high-contrast, rotationally asymmetric markers are recommended. Uploadable content includes GLTF, GLB, or ZIP 3D objects, JPG, PNG, or GIF images, and MP4 videos. Maximum upload sizes are 50 MB for 3D objects, 15 MB for images, and 25 MB for videos. Published experiences run on the web without requiring viewers to install another app. Publishing requires a GitHub login and depends on a privately hosted OAuth server that may become unavailable. The documented fallback is self-hosting a fork and Gatekeeper. The repository is MIT licensed.

Reality Composer is an Apple app for prototyping and producing augmented reality experiences without prior 3D experience. Its visual editor lets users place and rotate virtual objects in an AR scene or on a canvas, using objects from its built-in library or imported USDZ files. Finished scenes can be exported as USDZ. The app also supports guided LiDAR photogrammetry capture on iPhone 12 Pro or later and iPad Pro 5th generation or later. Projects can be transferred between the iOS app and the Reality Composer app bundled with Xcode for Mac, and scenes can be shared for viewing on iPhone and iPad through AR Quick Look. The listing covers iOS, macOS, and Windows; its App Store requirements are iOS 17.0 or later on iPhone and iPadOS 17.0 or later on iPad. Reality Composer is free. Apple says it may collect usage data for product interaction analytics that is not linked to the user. Reality Composer Pro 3 is a separate Mac tool for preparing 3D content for visionOS and iOS apps, with live preview on Apple Vision Pro.
