Recreate your services in Astrocal
Use the Astrocal dashboard to set up equivalent event types, or POST to /v1/event-types if you prefer the API. Match your durations, availability, and booking rules.

Frequently asked questions
Cal.com's free tier requires you to self-host: you set up Docker, a database, and manage the infrastructure yourself. Their managed cloud product starts at $12/seat/month. Astrocal's free plan is fully hosted with no setup required.
Open source gives you control over the code, but it also gives you ops work: server management, database backups, security patches, upgrades. If you'd rather spend time building your product than maintaining scheduling infrastructure, a hosted API is the better trade-off.
Astrocal covers the core scheduling workflow: event types, availability, bookings, calendar sync, Stripe payments, webhooks, round-robin, and a whitelabel widget. Cal.com has features Astrocal doesn't, like routing forms, collective events, and HIPAA compliance. Both have MCP servers. Astrocal's differentiators are the DOM-native widget embed, zero ops hosting, and flat-rate pricing.
Yes. Run both in parallel: set up Astrocal, test your booking flow, and only switch your public links once you're happy. There's no requirement to shut down Cal.com first.
About 20 minutes for most teams. Recreate your event types, connect your calendars, and update your booking links. If you were self-hosting, you also get to decommission that infrastructure.
Yes. Up to 10 bookings per month, full API access, webhooks, and calendar sync. No credit card required. No time limit. And no Docker containers to run.
