Can guests reply without an account?

Yes. Guests open the public link and answer.

How do I set an RSVP deadline?

Set close_at in the form settings. The form closes then. You can reopen it.

How do I count how many are coming?

Count the rows where attending starts with Yes. Add the guest_count values.

RSVP form template: collect replies with one link

It asks guests if they can come, how many they bring and any food needs. Share one link. Read the replies as JSON or CSV.
