Astrocal

Honest take: when Calendly is fine

If you need a simple personal scheduling link (no embedding, no API, no custom branding), Calendly does that well. It's been around a long time, it works, and if that's all you need there's no reason to switch.

Astrocal is built for a different problem: teams who need scheduling to live inside their own product, behave like infrastructure, and connect cleanly to their stack.

Who should switch

Which is right for you?

Astrocal is right for you if...

  • You're building scheduling into your own product and need a real API
  • You need true whitelabel: zero third-party branding on any plan
  • You want flat-rate pricing with no per-seat charges as your team grows
  • You need AI agents to check availability and create bookings via MCP
  • You want webhooks and full read/write API access on the free plan
Start free, no CC required

the competition is right for you if...

  • You just need a personal scheduling link with no integration requirements
  • You rely on Calendly's large third-party app marketplace
  • Your team is already deep in Calendly's enterprise admin tooling

Frequently asked questions

Yes. The free plan includes 10 bookings per month, full API access, webhooks, and Google Calendar sync. No credit card required.
API access is the most common reason. Calendly's API is read-only and rate-limited, so you can pull data out but you can't create or manage bookings programmatically. Astrocal's API is full read/write. The second most common reason is pricing: Calendly charges per seat, Astrocal charges a flat rate regardless of how many team members you have.
Your Calendly links will need to be updated. There's no automatic redirect from calendly.com to Astrocal. If you embed the widget on your own domain, your booking URL doesn't change at all.
Google Calendar, Microsoft 365, CalDAV, Stripe, and webhooks are all supported. For anything else, the full REST API and webhook system let you build any integration yourself.
Most teams are fully migrated in under an hour. The steps are: recreate your event types, reconnect Google Calendar, update your booking links or embed the widget. See the migration guide above.
