From the project's own README (excerpt, reproduced for discovery under its MIT license):
> Use at your own risk. Cal.diy is the open source community edition of Cal.com and it is intended for users who want to self-host their own Cal.diy instance. It is strictly recommended for personal, non-production use. Please review all installation and configuration steps carefully. Self-hosting requires advanced knowledge of server administration, database management, and securing sensitive data. Proceed only if you are comfortable with these responsibilities.
> For any commercial and enterprise-ready scheduling infrastructure, use Cal.com, not Cal.diy; hosted by us or get invited to on-prem enterprise access here: https://cal.com/sales

About Cal.diy
Cal.diy is the community-driven, fully open-source scheduling platform — a fork of Cal.com with all enterprise/commercial code removed.
Cal.diy is 100% MIT-licensed with no proprietary "Enterprise Edition" features. It's designed for individuals and self-hosters who want full control over their scheduling infrastructure without any commercial dependencies.
What's different from Cal.com? • No enterprise features — Teams, Organizations, Insights, Workflows, SSO/SAML, and other EE-only features have been removed • No license key required — Everything works out of the box, no Cal.com account or license needed • 100% open source — The entire codebase is licensed under MIT, no "Open Core" split • Community-maintained — Contributions are welcome and go directly into this project (see CONTRIBUTING.md)
> Note: Cal.diy is a self-hosted project. There is no hosted/managed version. You run it on your own infrastructure.
Built With • Next.js • tRPC • React.js • Tailwind…

Trust Passport
Full passport →0/0 automated components pass. An automated score is never a security guarantee.
This listing is unclaimed, so publisher identity cannot be verified and it stays below the “verified” tier by design — that is a statement about the listing, not about the project’s quality. Our automated scans still ran; a maintainer who claims it unlocks identity verification.
- publisher identity Publisher status verified; 0 verification(s) on file
- malicious pattern scan No known malicious-behavior patterns detected in reviewed content
- capability contract All 0 observed capability reference(s) match the declared manifest
- agent safety scan No injection patterns in agent-readable content
- provenance No release signature or provenance attestation
- behavioral sandbox Not performed in this environment — requires the production isolated runner (docs/sandbox-requirements.md). No untrusted code is ever executed on the application host.
Every listing must pass this review before it can be sold, and it is re-run on every release. Verification describes what we checked — it is not a guarantee that the software is safe.
