AR.js Studio vs Arkio

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.

Arkio is a design collaboration tool for architects and other spatial designers. Its solid-modeling tools support boolean operations and parametric volumes, while meeting participants can view and edit the same scene together in real time. For design review, users can save views, add voice-transcribed notes, make AI renders, and collaborate on 2D frames. Plugins connect Arkio with Archicad, Navisworks, Revit, Rhino, and SketchUp for model and related-data import or export. The free Starter plan includes the modeling tools, one-on-one meetings, and OBJ, GLB, and image import and export. Pro allows up to six meeting participants and includes 500 AI credits per month; it costs $35/user/mo with annual billing or $45/user/mo with monthly billing. Enterprise supports up to 24 participants and includes 1,000 monthly AI credits per license. Each AI render uses one credit, and credits renew monthly. Arkio runs on Android, iOS, macOS, and Windows. A Pro license can be installed on two devices but used on only one at a time.
