Scheduling and meetings decision
Kumospace
A competent engineer can build a usable, small-scale spatial-audio room and chat in several weeks, but reproducing Kumospace’s enterprise compliance, scale, polished cross-platform apps, and SLAs is costly—keep paying if you need those.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Kumospace alternatives, with the arithmetic →
What a replacement has to do
- Join a shared space, move an avatar around a 2D floor, speak with proximate participants (spatial audio/video), and send chat messages.
What it still won’t have
- Enterprise-grade compliance and certifications (SOC2/HIPAA/GDPR) without costly audits
- Scale and reliability for large concurrent events (thousands of attendees)
- Polished cross-platform native apps and frequent content/furniture drops
- Built-in onboarding/on-site support and SLAs
- Deep integrations and single-sign-on ready for enterprise
What remains hard
- Compliance and regulation
Kumospace is fully SOC 2, HIPAA, and GDPR compliant.
- Brand trust

Runnable build prompt
Build a minimal browser-based virtual space using Next.js (React) + TypeScript, PostgreSQL, Redis, and Node.js. Implement: 1) a Next.js web client with a 2D floor/map and keyboard/mouse avatar movement; 2) a Node signalling server (WebSocket) to exchange WebRTC SDP and coordinate presence; 3) WebRTC peer connections with a TURN server (coturn) for NAT traversal and server-side optional SFU (mediasoup or Janus) if >8 peers; 4) positional audio calculation on the client (pan/volume from x,y deltas) and chat persisted in Postgres; 5) simple auth (email+password) and per-space membership management; 6) an admin UI to create/manage spaces and view basic analytics. Out of scope: enterprise SSO, HIPAA/SOC2 certification, native mobile apps, white-labeling, and large-scale broadcast streaming. Require: error handling for signalling/ICE failures, connection retries, server and client tests (unit + integration for signalling and WebRTC flow), Docker-based deployment, and monitoring alerts for TURN and signalling errors.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
