About

Cal.com is an open-source scheduling platform (a Calendly alternative) that lets individuals and teams share booking links, manage availability, and embed scheduling into their own products via API. Its self-hostable, developer-friendly design and team routing features make it popular with startups that want control over their booking flow.
