Cal.diy: open-source community edition of cal.com

https://github.com/calcom/cal.diy

Article

  • Cal.com releases cal.diy as open-source community edition of scheduling platform
  • Strictly recommended for personal, non-production use per docs
  • No public Docker images provided; users must build themselves
  • Positioned as self-hosted alternative for non-enterprise users

Discussion

  • Commenters note sharp reversal: cal.com previously promoted on-prem for enterprise security
  • Suspicion it’s preemptive move to control open-source forks before community splits
  • calrs flagged as younger, promising alternative with fewer restrictions
  • Questions raised about vendor-compromise risk and calendar data access levels
