Overview
Cal.com is an open-source scheduling platform that positions itself as the privacy-respecting, developer-friendly alternative to Calendly. The cloud-hosted version has a generous free plan; the self-hosted version is completely free. Cal.com supports all the core scheduling scenarios — 1:1 booking, round-robin team routing, collective events, and paid bookings via Stripe. Its API and embeddability make it popular with developers and tech-forward businesses. The routing forms feature directs bookers to the right team member based on answers.
