Chat

№ 01.3 · part of the suite

End-to-end encrypted team chat with voice, video and screen share.


What it does

Team channels and direct messages with end-to-end encryption on by default — your messages live on your server, not someone else's. Threads, replies, reactions, voice notes and screen share work the way your team already expects from Slack or Teams. The desktop and mobile apps are real native clients, not browser wrappers.

End-to-end encryption on by default

Direct messages and team rooms — only the people in the room can read what's said. Your server holds ciphertext only.

Native desktop apps

Real desktop clients on Windows, macOS and Linux — system tray, native notifications, persistent presence, secure key backup.

✓ Included in every tier


Also included

The operational layer.

Native iOS and Android apps

Push notifications, on-device decryption, secure key backup.

Cross-signing and secure backup

Verify your devices, recover your encryption keys if a phone is lost.

Federation off by default

Your tenant is closed unless you explicitly open it — no surprise outside contact.

Screen share, file share, voice messages

Polls, locations and reactions inside any room.

Bridges available

Connect to IRC, Slack, WhatsApp or SMS during a migration window.

One thing to know

Group video calls scale fine for SMB-sized rooms; very large town-halls are better served by /office/videoconference.


Available in

Every tier — in the browser.

Chat ships in Core, Mesh and Fleet — same software, same features. The difference between tiers is operational: Mesh and Fleet add a desktop launcher and (for applicable apps) a sync client, and Fleet adds the managed laptops we ship with everything pre-configured.
