Frequently asked questions about Cal.com
Is Cal.com really open-source?
Yes — the Cal.com core is AGPL-licensed on GitHub (32k+ stars) and can be self-hosted with full feature parity to the cloud version. The hosted cal.com is the same code as the open-source repository. Commercial licenses are available for users who want to embed Cal.com in a closed-source product without AGPL obligations. The transparency is a key reason Cal.com has displaced Calendly in privacy-sensitive and compliance-bound markets.
Is Cal.com free?
Yes — Cal.com has a free tier (Individual, unlimited 1-on-1 bookings) on the hosted cloud, and self-hosting is free indefinitely. Paid plans start at $15/user/month (Teams) and add team scheduling, round-robin, routing forms, and removal of Cal.com branding. Calendly's equivalent plans start at similar prices but without the self-host option. For solo professionals, Cal.com free is fully sufficient.
How does Cal.com compare to Calendly?
Cal.com is open-source (AGPL), self-hostable, with team scheduling features on cheaper tiers, and a more developer-friendly extension ecosystem (Cal.com Atoms components for embedding scheduling in your own React app). Calendly has better mobile apps, broader brand recognition, and more polished workflow automations. For developer-adjacent companies and EU compliance buyers, Cal.com wins. For non-technical SMBs, Calendly's onboarding is friendlier.
Can I self-host Cal.com?
Yes — Cal.com publishes a Docker Compose stack and a Next.js codebase that runs on a 2GB VPS for small teams. PostgreSQL is the only mandatory dependency. Self-hosting gives unlimited users, full feature access, and zero ongoing fees. Many EU companies under GDPR scrutiny self-host Cal.com specifically to keep meeting metadata (which contains personal data) under their own control rather than on US SaaS.
Who uses Cal.com in production?
Cal.com is used by Vercel, Deel, Replit, Resend, and many YC-backed startups founded after 2022. It is also adopted by enterprises that require on-prem deployment (banks, healthcare, EU public sector) and by open-source maintainers who refuse to send their meeting metadata to a US SaaS. The community of self-hosters is large — the AGPL license has been a net adoption positive in privacy-conscious segments.
Where Cal.com is heading (12-24 months)
- →Cal.com Atoms (embeddable React components) is a strategic vector for Cal.com becoming scheduling infrastructure for other products.
- →AI scheduling (find time across multiple participants, AI-suggested meeting types) is shipping in 2026.
- →Workflow automation (multi-step post-booking sequences) is closing the gap with Calendly's Workflows.
- →Enterprise depth (SSO, SCIM, audit logs) is the main growth frontier in the displaced-Calendly segment.
