Cal.com

Cal.com is an open-source scheduling and appointment booking platform for individuals and teams. It provides customizable booking pages, calendar availability, and workflows to coordinate meetings across multiple participants and organizations.

Key Features

• Public booking pages with event types, buffers, limits, and configurable availability
• Team scheduling features such as round-robin/collective scheduling and managed availability
• Integrations for calendars and conferencing tools (e.g., Google Calendar, Microsoft, Zoom/Meet), plus webhooks
• Embeddable booking components for websites and products (embed/iframe options)
• Routing and intake forms to qualify requests and direct bookings to the right person/event
• Payments support for paid bookings (via Stripe integration)
• Multi-user and organization support with admin controls and role-based access options

Use Cases

• Customer-facing appointment booking for sales, support, and professional services
• Internal team scheduling (1:1s, interviews, office hours) with shared availability
• Product-embedded scheduling for marketplaces or SaaS onboarding flows

Limitations and Considerations

• Some advanced enterprise capabilities and managed services are offered as paid features; self-hosted deployments may require additional configuration for SSO, email, and integrations.

Cal.com is well-suited for organizations that want full control over scheduling UX and data while integrating with existing calendar and conferencing ecosystems. Its embeddable approach and team scheduling options make it useful both as a standalone scheduler and as scheduling infrastructure inside other products.
