Cal.com

Cal.com is a scheduling platform built for individuals, teams, enterprises, and developers that need flexible control over how meetings are booked and managed. Users can connect calendars, define availability, create booking pages, set different event durations, add buffers and booking limits, and automatically handle timezone differences and scheduling conflicts. The Individual plan includes unlimited event types, unlimited calendar connections, email and SMS notifications, payments through Stripe and PayPal, and access to more than 100 integrations.

For teams, Cal.com supports Round Robin scheduling, collective meetings, shared availability, recurring events, managed event types, booking analytics, customizable notifications, and routing forms. Its routing capabilities can direct prospects according to attributes such as region, role, company information, or CRM ownership, while integrations with Salesforce and HubSpot support two-way synchronization and lead routing.

Cal.com also includes workflow automation for reminders, follow-ups, SMS, email, and other scheduling actions. Cal.ai adds AI-powered voice scheduling that can call participants to book, confirm, reschedule, cancel, or follow up on meetings. AI calls are usage-based and currently cost $0.29 per minute.

For AI and developer workflows, Cal.com provides APIs, webhooks, SDK-style scheduling components, and an MCP server that connects compatible AI assistants to bookings, schedules, event types, availability, routing forms, and other Cal.com functions through natural language.

Enterprise capabilities include SAML SSO, SCIM, role-based permissions, domain-wide delegation, dedicated databases, US or EU hosting, SOC 2 Type II, ISO 27001, GDPR, CCPA, and HIPAA support. Cal.com’s managed production platform is no longer fully open-source; since 2026, its open-source self-hostable edition is maintained separately as Cal.diy.
