Frame vs MindAR

Frame is a browser-based platform for building private or public virtual spaces for businesses, schools, organizations, and communities. Its collaborative tools include spatial voice chat, translated text chat, whiteboards, webcam and screen sharing, shared browsers, and live co-editing. A drag-and-drop editor accepts 3D models, 360 photos and videos, images, video, PDFs, streaming screens, shaders, particle systems, buttons, and proximity triggers. AI options include image and skybox generation, GPT-powered chat, AI NPCs, translation in 30 languages, and speech-to-text captions. A Frame can hold up to 300 people; larger spaces up to 1,000 may be possible with suitable settings and support contact. It runs in desktop, mobile, and VR browsers without downloads. The mobile guide recommends Safari on iOS and Chrome on Android, but notes that mobile lacks screen sharing and laser pointers. The listed tiers are $10, $50, and $200 per month, alongside a free trial; educators can get a 50% discount.

MindAR is a free, open-source web augmented reality library for image tracking and face tracking. It runs in plain static HTML, through an HTML script or npm, and integrates with A-Frame and Three.js using separate image- and face-tracking builds. Image tracking uses a device camera to detect a target and place an augmented object; face tracking detects a face for experiences such as virtual try-on. A browser tool compiles image targets. The project says WebGL and web workers support performance, and static HTML examples can be hosted anywhere. Three.js integration requires version 137 or later, with Three.js kept as an external dependency. Examples require camera access and a webcam for desktop testing. The library uses the MIT License. MindAR Studio is a related free drag-and-drop face-tracking tool that exports self-hosted webpages. Location and fiducial-marker tracking are outside its stated scope.
