Scheduling infrastructure for absolutely everyone. - calcom/cal.diy
Summary

Cal.diy is a community-maintained, MIT-licensed fork of Cal.com that removes all enterprise features (Teams, SSO, Insights) and license key requirements. Built with Next.js, tRPC, Prisma, and Daily.co, it requires self-hosting on Node.js >=18.x and PostgreSQL >=13.x, but is explicitly recommended for personal, non-production use only. The project offers full control over scheduling infrastructure without commercial dependencies, though it demands advanced server administration skills.
