About Cal.com

Cal.diy is the community-driven, open-source edition of Cal.com, distributed as a GitHub repository. It is a fork with enterprise and commercial code removed, released under the MIT license with no proprietary Enterprise Edition features, and is intended for individuals and self-hosters who want to run scheduling infrastructure on their own servers. There is no hosted or managed version.

Setup requires Node.js 18.x or later, PostgreSQL 13.x or later and Yarn, along with the server administration, database management and data-security skills needed to operate the stack. The repository warns that it is strictly recommended for personal, non-production use, and directs commercial or enterprise-ready scheduling needs to Cal.com.
