What you give up vs Calendly
- Some enterprise features (e.g. SAML SSO, advanced admin/insights, certain platform features) are gated behind a commercial/EE license even when self-hosting.
- Self-hosting requires PostgreSQL plus configuring numerous environment variables and OAuth credentials for calendar integrations.
- The core code is AGPL-3.0, which imposes copyleft obligations on modified network deployments.
- Upgrades between major versions occasionally require manual database migration work.
What you gain
- • Full data ownership — self-host Cal.com on your own infrastructure.
- • No per-seat SaaS bill (Calendly: per-seat fees for multiple event types).
- • Open-source code you can audit and extend (AGPL-3.0).
