[!WARNING]  
 Use at your own risk. Cal.diy is the open source community edition of Cal.com and it is intended for users who want to self-host their own Cal.diy instance. It is strictly recommended for personal, non-production use. Please review all installation and configuration steps carefully. Self-hosting requires advanced knowledge of server administration, database management, and securing sensitive data. Proceed only if you are comfortable with these responsibilities.

 [!TIP]
 For any commercial and enterprise-ready scheduling infrastructure, use Cal.com, not Cal.diy; hosted by us or get invited to on-prem enterprise access here: https://cal.com/sales

 About Cal.diy



Cal.diy is the community-driven, fully open-source scheduling platform — a fork of Cal.com with all enterprise/commercial code removed.

Cal.diy is 100% MIT-licensed with no proprietary "Enterprise Edition" features. It's designed for individuals and self-hosters who want full control over their scheduling infrastructure without any commercial dependencies.

 What's different from Cal.com?

- No enterprise features — Teams, Organizations, Insights, Workflows, SSO/SAML, and other EE-only features have been removed
- No license key required — Everything works out of the box, no Cal.com account or license needed
- 100% open source — The entire codebase is licensed under MIT, no "Open Core" split
- Community-maintained — Contributions are welcome and go directly into this project (see CONTRIBUTING.md)

 Note: Cal.diy is a self-hosted project. There is no hosted/managed version. You run it on your own infrastructure.
