WHAT IS IT?
Cal.com is an open-source scheduling platform positioned as the successor to Calendly. You create booking pages, connect your calendars and your guests pick an available slot. The whole thing is self-hostable, white-label by default and driven by an API to integrate into any product.
WHY IS IT INTERESTING?
- Native white-label : designed from the ground up to be customized and deployed on your own domain, with no Cal.com branding visible to your users
- API-first : tRPC architecture that lets you integrate booking flows in headless mode into your existing application
- Self-hostable : deploy via Docker, Railway, Render or Vercel — you keep full control of your scheduling data
- Calendar integrations : native sync with Google Calendar, Outlook, Apple Calendar and other providers
- Flexible event types : variable durations, collective events, round-robin across team members and recurring bookings
- Workflows and automation : customizable reminders, confirmations and notifications via email and SMS
