Relm review
A customizable browser-based meeting world for teams that want open-source spatial collaboration.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Relm is an open-source, browser-based 3D spatial platform for meetings, collaboration, communities, and online events. Participants appear as customizable avatars in shared virtual environments, with in-world audio and video conferencing, text chat, permissions, and collaborative world-editing tools. It is aimed at communities, life coaches, guides, remote groups, and open-source teams that want online interaction to feel more spatial than a conventional meeting interface. Relm can run through the vendor’s service or be deployed on an organization’s own server.
Its standout capability is the combination of a multiplayer 3D environment and a collaborative world editor. Teams can create or modify shared spaces while using proximity and group audio modes, which supports different interaction patterns within the same environment. Shared rich-text documents and whiteboards extend the workspace beyond conversation, while read, access, and edit permissions provide control over participation. This makes Relm a fit for organizations that value customization and want to shape the environment around their community or event format.
Relm’s open-source model and self-hosted platform are important advantages for teams that want more control over deployment and world design. At the same time, its scope is concentrated on web-based spatial experiences, with no AI features and platform coverage centered on web and self-hosted use. Teams seeking a customizable 3D meeting environment should consider Relm; organizations looking for a broader meeting ecosystem or a simpler room-based workflow may prefer a more conventional alternative.
