MEET

From message to call in one click.

Voice and video calls in any DM, group or channel, with screen sharing and live cursors. The audio and video run through a media server in your own stack.

LiveKit + coturn · inside your Docker Compose stack

Overview

Ringing, banners and one-click joins.

DMs ring the other person, and channels show a join banner, so nobody has to paste a link.

Point at the thing.

Share your screen, and everyone’s cursor shows on it with a neon trail, so “click there” means something.

Calls that tidy up after themselves.

When only one person is left, the call ends, and the chat gets a card with who joined and for how long.

FOR ADMINS

What admins control.

Moderation.
The person who starts a call can mute others, stop a share or remove a participant.
Who can call.
Permissions decide who can start calls and record them.
Your network.
Media flows through the LiveKit server and TURN relay in your stack.
Sizing.
Call quality depends on your server and bandwidth. See Self-hosting for what production has run on.

Use cases

  • ENGINEERING

    Pair on a bug.

    Screen share in #design-review, then open a whiteboard.

  • OPS

    Morning stand-up.

    One click in #ops-oncall; the call ends when the last person leaves.

And so much more.

  • Deafen and per-device mic and camera menus
  • Speaker and grid layouts
  • Pin a tile for yourself

  • Calls from the desktop app with screen sharing

Questions.

Something else? Talk to us
Do calls go through a third party?

No. Smack ships a LiveKit media server and a TURN relay in its Docker Compose stack, on your server.

How many people can join a call?

It depends on your server’s CPU and bandwidth. We size it with you during installation.

Can I share one window instead of my whole screen?

Yes. The browser or the desktop app lets you choose a screen, a window or a tab.

What happens if I forget to hang up?

The call ends when only one person is left.

Can guests from outside join calls?

Use Meetings with guests: they join with a link and their name.
