Frame vs Meetropolis

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.

Meetropolis is an open-source virtual office for remote teams, set in a live 2D world with proximity-based spatial audio and video. Guest access and screen sharing are available. Phaser provides the live-world layer, while Colyseus powers real-time multi-user interaction. Teams can use the web application or self-host it with the supplied Docker Compose setup, which includes the web app, server, database, and LiveKit service. The self-host configuration uses PostgreSQL and documents SMTP email settings for invites, guest magic links, verification links, and welcome messages. Personal API tokens can control microphone, camera, screen sharing, and do-not-disturb status. Server components use AGPL-3.0-only; the web client and shared types use MIT. Tiamat UG offers a commercial license. The open-source server permits 25 concurrent users across the whole server, and the 26th user is kicked. Production self-hosters must supply a TLS terminator, configure production secrets and allowed CORS origins, and may need TURN for restrictive networks.
