Create an event type

Sign up, connect Google Calendar with one click, and configure your availability: weekly hours, buffer times, and booking windows. All via dashboard or API.

Embed or share

Drop a single script tag on any website, use the npm package in your app, or share a hosted booking link. The widget renders natively in the DOM, not an iframe, so it inherits your styles.

Let the system run

Bookings sync to your calendar automatically. Confirmation emails with ICS attachments go out instantly. Webhooks notify your stack. Cancellations trigger refunds. You handle zero of it manually.

Everything you need out of the box

💳

Collect deposits at booking

Stripe Connect built in. Require a deposit or full payment when someone books, not when they show up. SCA-compliant, 135+ currencies.

✉️

Automatic reminders

Confirmation and reminder emails with ICS calendar attachments sent automatically. Cancellation notices included. No third-party email integration needed.

📅

Real-time calendar sync

Google Calendar FreeBusy checks run on every slot request. If your calendar is blocked, that slot disappears. New bookings write back as events automatically.

🎨

Whitelabel everything

CSS custom properties give you full control over colours, fonts, and layout. On paid plans, all Astrocal branding is removed. Your customers see your brand only.

💰

No per-seat fees

Plans are flat-rate based on booking volume, not team size. Add your whole team: round-robin scheduling, shared event types, and team calendars included.

Frequently asked questions

No. The dashboard lets anyone create event types, set availability, and manage bookings without writing code. The API and widget are there for teams who want deeper integration, but they are entirely optional.

Google Calendar, Microsoft 365 / Outlook, and any CalDAV-compatible calendar (Apple Calendar, Fastmail, Nextcloud). All three providers use OAuth for connection.
Yes. The @astrocal/mcp-server npm package gives any MCP-compatible AI agent (Claude, Cursor, or your own) the ability to check availability and create bookings directly.
Yes. The free plan includes full API access, Google Calendar sync, the embeddable widget, and 10 bookings per month. No credit card required.
