Cal.diy is the fully open-source, MIT-licensed community edition of Cal.com, a scheduling platform for booking meetings and managing availability. It is a fork with all enterprise/commercial features removed, intended for individuals self-hosting their own instance.

Use cases

• self-host a Calendly alternative for booking meetings
• let clients book time slots on my own domain
• run a personal scheduling page without commercial dependencies
• sync bookings with Google Calendar and Zoom
• host scheduling infrastructure on my own server with Docker
• replace Cal.com's hosted service with a fully open-source instance

When to choose

• you want a 100% MIT-licensed scheduling tool with no enterprise edition restrictions
• you are comfortable self-hosting with Node.js, PostgreSQL, and Docker
• you need personal, non-production scheduling for yourself or a small group
• you want full control over your booking data and integrations

When to avoid

• you need enterprise features like teams, organizations, SSO/SAML, workflows, or insights
• you require commercial-grade support and security guarantees for production use
• you don't have server administration and database management experience
• you want a zero-maintenance hosted solution
