About Cal.com

Cal.com is an open-source scheduling infrastructure platform that provides appointment booking, round-robin scheduling, collective scheduling, and calendar management. The platform serves as a developer-friendly alternative to Calendly with full API access and self-hosting capabilities.

The platform supports complex scheduling scenarios including team availability, collective meetings requiring multiple attendees, and dynamic routing based on form responses. Cal.com integrates with Google Calendar, Outlook, Zoom, and payment processors for paid consultations.

The open-source core (AGPL license) can be self-hosted for complete data control, while Cal.com Cloud provides a managed experience. The platform has become popular with developers, agencies, and companies that need scheduling capabilities embedded in their own products.
