Cal.com API
Cal.com's open-source scheduling API for managing availability, event types, bookings, and calendar integrations — available as cloud or self-hosted.
Best When
An agent needs full API control over scheduling including creating event types, or when self-hosting is required for data privacy.
Avoid When
You need a no-code scheduling solution or are looking for Calendly's specific integrations.
Use Cases
- • Creating and managing event types and booking pages programmatically
- • Reading and managing bookings for automated workflows
- • Setting availability schedules for teams and individuals
- • Building custom scheduling interfaces with full API control
- • Self-hosted scheduling with data residency requirements
Not For
- • Teams needing Calendly's polished UI without development effort
- • Very simple one-person scheduling without API needs
- • Teams without technical resources for self-hosting (use cloud instead)
