Large audiences with metered billing
Pro lists 3,000 maximum live attendees per event while charging attendee credits only when someone actually joins, but exhausting the yearly credit pack blocks new joins until you upgrade.
“Maximum live attendees A live attendee is a unique person joining your Livestorm event. 3000 / event”
“People who register but never show up are not counted, so you never pay for no shows.”
“If you fully reach your quota, new attendees will not be able to join sessions until you upgrade.”
