Adding multi user review sessions to existing Unreal and Unity apps

Cavrnus is a Carlsbad, California company that builds the Cavrnus Spatial Connector (CSC), a drop in plugin that turns existing Unreal Engine and Unity applications into persistent multi user workspaces. The connector adds synchronized object state, copresence with avatars, WebRTC voice and video, and AI transcription and translation in more than 50 languages without rebuilding the host application.
Every interaction in a session is logged to a Journal that keeps state synchronized and persistent between sessions. Cavrnus encrypts data end to end, offers a Virtual Private Cloud option and on premise deployment, and supports Okta, Microsoft Entra ID and SAML authentication on its enterprise tier. Typical uses are design review, facility walkthroughs and training.
The Unity plugin builds for Windows, macOS, iOS, Android, AR and VR headsets and visionOS, which covers Apple Vision Pro. The Unreal Engine plugin is a free download on Fab, runs on Windows today with macOS, iOS and Android listed as coming soon, and works with Pixel Streaming. Web experiences connect through .NET and JavaScript SDKs.
Cavrnus's connection to radiance fields runs through Miris. In April 2026 the two companies announced an integration that streams radiance fields into Cavrnus sessions, so teams can review and annotate full fidelity streamed assets together instead of simplified proxies. The integration is in development and has not shipped. Miris streams to the end device with no cloud GPU in the loop, and the feature is due to reach users with a Cavrnus account when it launches.
The free plan supports up to five concurrent users with unlimited team members and no credit card. Pro costs $80 a month billed yearly, includes ten concurrent users and a commercial licence, and adds users at $8 a month each. Enterprise pricing is custom.
