## What it is
[!WARNING] 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.

## When to use it
Reach for cal.diy when you'd rather own a ready-made product (analytics, CMS, CRM…) than pay for SaaS — it's written in TypeScript and fits stacks tagged next-auth, nextjs, postgres, prisma.
