Company information

The facts on file

Description
Cal.com is open-source scheduling and booking infrastructure that positions itself as "scheduling infrastructure for absolutely everyone," offering a free unlimited single-user plan plus paid Teams, Organizations and Enterprise tiers. It is aimed at individuals wanting a Calendly substitute, developer-led teams embedding scheduling via API/React atoms, sales teams needing round-robin and routing, and compliance-conscious organisations needing SAML SSO and SOC 2/HIPAA/ISO 27001 coverage. A self-hosted route exists via the public calcom/cal.com GitHub repository.

Regulatory
SOC 2, HIPAA and ISO 27001 compliance are claimed only at the Organizations tier and above, so HIPAA-covered buyers cannot rely on the Free or Teams plans. The codebase is public on GitHub (calcom/cal.com), but the specific licence terms — historically a non-Apache commercial licence for enterprise features — were not verified this session and should be confirmed before commercial self-hosting. Legal entity: Cal.com, Inc.; Trustpilot profile claimed June 2022 on a paid subscription, mild context on review solicitation.
