AR.js Studio vs WorldCAST

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.

WorldCAST is a browser-based, no-code platform for creating and publishing interactive WebAR experiences. Its PrintCAST studio adds video, audio, 3D models, buttons, and links to print materials, with audience analytics. GeoCAST places content at an address or geographic coordinate for discovery through a QR code, geofence, or link. ShowCAST uses SLAM to place digital content at real-world scale in a space. Canva is integrated into PrintCAST, and the maker says users can access Sketchfab 3D models within the studios. Creators can monitor audience use; Advanced Analytics is included in the paid Upgrade plan. Creator costs nothing and includes all studios, basic analytics, unlimited monthly views, and no expiry date. Upgrade costs $10 a month per CAST. No software download or app is needed to create or access browser-based experiences, but the webAR editor is optimized for laptops and desktop computers rather than mobile. PrintCAST and GeoCAST accept videos up to 100 MB; ShowCAST does not support audio or video.
