Everything in one world
No more switching between Gather for presence, Discord for chat, and Zoom for calls.
The World Drives Everything
Walk up to a colleague and their voice fades in automatically. Step into a Room zone and a video conference opens — no buttons, no scheduling. Your tile position is the interface.
- 4-directional movement on Tiled maps
- Earshot radius ring overlay
- 20Hz real-time position sync
- 3D HRTF spatial audio via Web Audio API
Zero-Knowledge Encryption
Every message is encrypted before it leaves your browser. The server stores opaque ciphertexts it can never read. Private keys never leave your device — not even for backup.
- X25519 ECDH + HKDF + AES-256-GCM
- WebAuthn PRF biometric key backup
- Epoch-based forward secrecy
- Web Crypto API — no third-party libs
Zone-Triggered Conferences
Walk into any Room zone and a LiveKit WebRTC video session opens automatically. Walk out and it closes. The map topology defines who can meet — naturally.
- LiveKit SFU WebRTC streams
- Expandable strip → full conference
- Screen sharing inside zones
- Guest invite links via JWT
Persistent Encrypted Channels
Discord-style text channels and 1-on-1 DMs, all zero-knowledge encrypted. Per-device ciphertext slices mean every trusted device can read its own messages independently.
- Channel E2EE with epoch rotation
- Per-device DM ciphertexts
- Real-time delivery via WebSocket
- Full message edit & soft-delete
Why not just use Discord?
Discord added audio/video E2EE in 2024 — but explicitly excludes all text messages. Gather.town has spatial presence but stores messages as plaintext. AtriumVerse is the only platform that closes all three gaps.
* Discord added audio/video E2EE via DAVE protocol (Sept 2024) but explicitly excludes text. Gather.town free tier capped at 10 users (2025).
Three steps to
your virtual office
Create a Space
Launch a server, pick a tile map (classroom or campus layout), and set it public or private. The backend parses spawn points and zones automatically.
Walk In
Pick your avatar — Bob, Alex, Adam, or Amelia. Your character spawns at your last saved position and other players appear in real time.
Collaborate Naturally
Walk up to someone to talk, enter a Room to video call, or type in an encrypted channel. Your position is the only control you need.
Built with proven tools
No exotic dependencies. The entire encryption stack runs on the browser's built-in Web Crypto API.
"The server never receives a plaintext message or private key at any point."
— AtriumVerse architecture guarantee
How the encryption works
Keypair Generation
On first login your browser generates an X25519 keypair. The public key goes to the server. The private key is stored only in IndexedDB — it never leaves your device.
Key Backup
You back up your private key using Face ID / Windows Hello (WebAuthn PRF) or a passphrase. The encrypted blob is stored server-side, unreadable without your biometric.
Sending a DM
ECDH between your private key and the recipient's public key produces a shared secret. HKDF(secret, message_id, 'dm-epoch:N') derives a per-message AES-256-GCM key.
Forward Secrecy
When a member leaves a channel the epoch increments, a new channel key is distributed to remaining devices, and the departing member cannot decrypt future messages.
Multiple tile worlds
Choose a classroom or campus layout — or upload your own Tiled JSON map.
