Open‑source scheduling tool, an alternative to Calendly. Supports multiple calendar integrations, custom pages, team booking, and self‑hosting.
Cal.com is an open‑source scheduling tool that lets clients or colleagues see your availability and book appointments. It integrates with Google, Outlook, iCloud, and offers customizable booking pages.
I embedded Cal.com on my personal site, and clients can book consultation slots. It syncs with my Google Calendar to avoid double‑booking. The free tier with one calendar is sufficient, and being open‑source means I can self‑host later if I want.
Cal.com simplifies scheduling without the limitations of Calendly’s free plan.
Pro tip: Cal.com supports webhooks—trigger automated emails or CRM updates when a booking is made.
