Calcom

Scheduling infrastructure, not just a booking page - Cal.com is the leading open-source scheduling platform. Share a link, attendees pick a slot, and real-time sync against Google Calendar, Outlook, and CalDAV prevents double-booking. Beyond the basics it covers team workflows: round-robin distribution, collective availability across multiple hosts, recurring meetings, and routing forms that ask bookers questions and send them to the right team member - the feature sales and support teams usually pay enterprise prices for. Paid bookings run through Stripe, video calls through the built-in Cal Video (Daily.co) or Zoom and Google Meet, and an app store connects 100+ tools including HubSpot, Zapier, and n8n. The API-first architecture with webhooks and embeds makes it practical to build scheduling into your own product, white-labeled with your domain and branding. Built on Next.js and Prisma over PostgreSQL, translated into 65+ languages, with the self-hostable community codebase maintained under an open-source license.

Benefits

  • Zero Per-Seat Fees
  • Calendly charges $10-16 per user per month. Self-hosted Cal.com serves an unlimited team for flat hosting cost, with routing forms and team features that Calendly gates behind higher tiers.
  • Fully Your Brand
  • White-labeling is built in: your domain, colors, and booking pages with no 'powered by' badge, where hosted competitors reserve that for enterprise plans.
  • Booking Data Under Your Control
  • Meeting metadata reveals clients, prospects, and internal cadence. Self-hosting keeps that graph on your infrastructure, which matters for HIPAA- and GDPR-sensitive organizations.
  • Scheduling as a Building Block
  • The API-first design with embeds and webhooks lets you ship scheduling inside your own product instead of bolting on a third-party widget.
