Cal.com

Cal.com is a modern, fully customizable scheduling and appointment booking platform designed to eliminate the back-and-forth of coordinating meetings across individuals, teams, and entire organizations. At its core, it enables users to create shareable booking links, set availability rules, and let clients or colleagues self-schedule meetings — all while integrating seamlessly with widely used tools like Google Workspace, Microsoft, Zoom, HubSpot, Salesforce, Stripe, and Zapier. For teams, the platform offers advanced features such as round-robin and collective booking, intelligent routing forms that direct meetings to the right person, and automated reminders and workflows that reduce manual follow-up. Cal.com is equally capable as an enterprise-grade solution, offering SOC 2 Type II, HIPAA, ISO 27001, GDPR, and CCPA compliance, along with SSO, SCIM provisioning, role-based access controls, and self-hosting options for organizations that require full data sovereignty. It is well suited for freelancers and solopreneurs who need a free, easy-to-use booking link, as well as for sales teams, customer success functions, healthcare providers, and large enterprises managing complex, high-volume scheduling operations across departments. Whether powering a startup's first sales calls or orchestrating enterprise-wide appointment systems, Cal.com provides the flexibility, security, and white-labeling capabilities to serve virtually any scheduling use case.
