About Cal.diy

Cal.diy is the community-driven, fully open-source scheduling platform, forked from Cal.com with all enterprise and commercial code removed. Unlike Cal.com's 'Open Core' model, Cal.diy has no proprietary Enterprise Edition features — Teams, Organizations, Insights, Workflows, SSO/SAML, and other EE-only functionality have been stripped out, and the entire codebase is released under the MIT License with no license key or Cal.com account required. It's built with Next.js, tRPC, React, Tailwind CSS, and Prisma, and supports integrations with Google Calendar, Microsoft Graph/Office 365, Zoom, Daily.co, Basecamp, HubSpot, Webex, Zoho CRM, Zoho Calendar, Zoho Bigin, and Pipedrive. Cal.diy is strictly a self-hosted project with no managed/hosted version, deployable via Docker Compose, Railway, Northflank, Vercel, Render, or Elestio. It's recommended for personal, non-production use, with the project explicitly noting that commercial or enterprise-ready scheduling needs should instead use Cal.com's official hosted or on-prem enterprise offering. The project is community-maintained, and contributions go directly into this fork rather than flowing back to Cal.com's production platform.
