Sound familiar?
of event hosts still manage RSVPs in a spreadsheet
A shared Google Sheet, a messy email thread, and a headcount that's never quite right. One tool should handle registration, capacity, and confirmation.
per event on manual registration admin
Confirming attendees, tracking payments, sending reminders, managing the waitlist. All before the event even starts. That time should go to preparation, not logistics.
of registered attendees don't show up
Without automated reminders and a financial commitment, people register and forget. Deposits and reminders together solve the problem.
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.
Capacity-limited bookings
Set a maximum number of attendees per slot. Astrocal stops accepting registrations when the event is full. No overbooking, no manual cutoff.
Collect payment at registration
Require a ticket fee or deposit at the point of booking via Stripe. Attendees pay when they register. Cancellation and refund policies are yours to set.
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 Google Calendar
Group events appear on your Google 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.

--astrocal-primary: #2563ebCreate a group event type
Set the event duration, capacity limit, and price. Choose recurring slots (e.g. every Wednesday at 7pm) or one-off dates. Connect your Google 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.
