Sound familiar?

is where most event RSVPs still live

A shared sheet, a messy email thread, and a headcount that's never quite right. One tool should handle registration, capacity, and confirmation.

eats the run-up to every event you host

Confirming attendees, tracking payments, sending reminders, managing the waitlist. All before the event even starts. That time should go to preparation, not logistics.

is the default attendee behavior without reminders or a deposit

A free RSVP costs nothing to skip. Automated reminders plus a ticket fee or deposit give people two reasons to turn up.

Booking pages that handle capacity for you

Astrocal group event types accept multiple bookings for the same time slot. Set a capacity limit and Astrocal stops accepting registrations when it's full. Collect payment at registration, send reminders, and track attendance automatically.

Automatic reminders

Email reminders go out 24 hours and 1 hour before every event. Attendees show up. Your no-show rate drops.

Webhooks on every registration

Every new registration fires a webhook with the attendee's details. Push data to your email tool, CRM, or any backend service automatically.

Syncs with your calendar

Group events appear on your connected calendar with the attendee count. Block dates for setup or personal time and those slots close automatically.

Your brand, not ours

Match your colours and fonts exactly. On paid plans, Astrocal branding disappears. Attendees see your event, not a third-party registration page.

Create a group event type

Set the event duration, capacity limit, and price. Add weekly availability, like every Wednesday at 7pm, so registration stays open. Connect your calendar so availability is always accurate.

Share the registration link

Post the link on your website, social media, or email list. Embed the widget directly on your site. Attendees pick a date, fill in their details, pay if required, and they're registered.

Run your event

Reminders go out automatically. Cancellations free up spots. Payment is already collected. You show up and deliver. That's it.
