See who's actually in the lobby

Before you open the room, the host sees a live roster of every student who's loaded the waiting room. Polled every 3 seconds. Stops dispatch confusion of 'is anyone here yet?'.

Last updated May 20, 2026

How presence is detected

When a student opens /p/<tenant>/live/<roomCode> before the host has opened the room, we register them as present in the lobby. The signal refreshes every 3 seconds — close the tab and they drop off within ~6 seconds.

Host view

  • Right rail on /dashboard/classes/<id>/host shows the lobby roster.
  • Names + initials, ordered by arrival.
  • A running count chip ('5 in lobby') updates live.
  • When you open the room, every lobby member auto-admits — no per-student click.

Why it matters

Hosts ship a punctuality stat to students ('Maya started 92% of past classes on time') because of this signal. The lobby roster tells you whether to wait for stragglers or kick off; the auto-admit removes the friction of admitting 30 students one-by-one.

Late joiners after you've opened the room skip the lobby — they auto-admit instantly and get the 'You missed: …' agenda banner so they catch up.
