A self-hosted scheduling platform for booking pages and meeting links, built for individuals who want no commercial dependencies.
Cal.diy takes the Cal.com scheduling platform and removes every piece of enterprise and commercial code from it. What remains is a booking platform for individuals and self-hosters, with no license key, no vendor account and no open core split to work around.
The stack is Next.js, tRPC, React, Tailwind CSS and Prisma, with Daily.co behind video calls. Running it needs Node 18 or newer and PostgreSQL 13 or newer, and a single dx command starts a local Postgres seeded with test users so you can sign in within minutes.
The fork changes what you get compared with the upstream product.
- No enterprise tier: Teams, Organizations, Insights, Workflows and SSO or SAML have been stripped from the codebase.
- No license key: everything works from a fresh checkout, with no Cal.com account required.
- MIT throughout: the whole codebase carries one permissive license rather than a split.
- Community maintained: contributions land directly in this project instead of an upstream commercial repository.
- Integrations: calendar and video connections each need their own credentials, obtained per provider.
There is no hosted version, so you run it on your own infrastructure. The maintainers describe it as suited to personal rather than production use, and warn that self-hosting demands real comfort with server administration, database management and handling sensitive data. Anyone who wants supported, commercial scheduling infrastructure is pointed back at the upstream product instead.
Self-hosted appointment scheduling system for any business, handling providers, services, working plans and bookings with Google Calendar synchronization built in.
Businesses that take bookings usually rent a scheduling service and hand over their customer list with it. Easy!Appointments puts the booking page and the calendar behind it on your own server, and adapts to the workflow you already have rather than the other way around.
It integrates with an existing website and database, so it slots into infrastructure a business already runs instead of replacing it. Use is free for personal and commercial purposes alike, with a premium tier selling further capabilities and professional services on top.
The feature set covers a standard booking operation.
- Appointments and customers: manage bookings and the customer records attached to them.
- Services and providers: organize what is offered and who delivers it.
- Working plans: define availability and the rules that govern what can be booked.
- Google Calendar sync: keep provider calendars aligned with the world outside the app.
- Email notifications: automatic messages around each booking.
- Multi-language interface: translations for teams and customers who do not share a language.
Production installation wants Apache or Nginx, PHP 8.2 or newer, and a MySQL database. You create a database, upload the folder, make the storage directory writable, rename and edit the sample config file, then finish in a browser-based setup wizard. Development uses the bundled Docker Compose environment on Linux, macOS or Windows with WSL, installing dependencies with npm and Composer inside the container.
