AR.js Studio vs Gravity Sketch

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.
