Hubs vs Meetropolis

Hubs is a browser-based virtual collaboration platform for creating shared 3D spaces that people can join by URL. Rooms support spatialized audio and text chat, as well as sharing images, videos, 3D models, and other media. The platform can host conferences, classes, art showcases, or remote social gatherings. Spoke, a browser-based scene editor, lets users build Hubs environments from 3D models, images, videos, and other assets; its media discovery includes a Sketchfab integration. Hubs is open source and customizable, and its Community Edition can be self-hosted. Administrators can configure an instance, import assets, manage users, and moderate contributed content. An account is not required to use Hubs, although some features require sign-in. It works with VR headsets and can also be explored in 2D on computers, tablets, and mobile devices. Community Edition is free software, but hosting, domain, and email services may have separate costs. The documentation warns that a significant portion is outdated and that Hubs by Mozilla and Hubs Cloud are obsolete.

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.
