Everything you need.

Not a bloated platform. A focused tool that does what matters.

Real-Time Messaging

Instant delivery, channels, groups, and file sharing.

Voice & Video

Crystal-clear calls powered by LiveKit.

Calls survive refresh

Active voice calls persist through page reloads and reconnect automatically (server-side call state).

Graceful reconnection

A 10-second grace period absorbs network drops before ending a call.

Friend-only presence

Online/offline status is only broadcast to friends, not the whole system.

Open Source

Audit every line. Self-host on your own server. No black boxes.

Built with care

A modern, open-source stack you can audit and self-host.
