What is Cal.diy Self-Hosting Documentation
Cal.diy is the community-driven, self-hosted distribution of the Cal.com scheduling infrastructure. Designed for developers and privacy-conscious power users, it provides a robust, white-label alternative to proprietary scheduling platforms. Unlike the commercial Cal.com SaaS offering, Cal.diy grants full control over data residency, database management, and infrastructure deployment. It leverages a modern stack optimized for containerized environments, allowing users to integrate third-party APIs like Zoom, Stripe, and Twilio directly into their own private instances. It is the ideal solution for technical teams requiring a customizable, self-managed booking engine without the constraints of a managed cloud service.
Cal.diy Self-Hosting Documentation 's Core features
Self-Hosted Infrastructure Control
Provides complete ownership of the application stack, allowing for deployment on private servers or VPCs. This ensures strict compliance with data sovereignty regulations by keeping all booking metadata, user information, and calendar logs within your own infrastructure, eliminating reliance on third-party cloud providers for data storage.
Containerized Deployment Architecture
Built natively for Docker, the platform supports seamless deployment across major cloud providers like Azure, Railway, and Render. This container-first approach simplifies dependency management, ensures environment parity between development and production, and allows for rapid scaling using standard orchestration tools like Kubernetes or Docker Swarm.
Extensible Integration Ecosystem
Includes native support for critical third-party APIs including Google Calendar, Microsoft Graph, Zoom, and Stripe. Developers can configure these integrations via environment variables, enabling automated video conferencing links, payment processing for paid bookings, and SMS notifications via Twilio without modifying the core application code.
Database Schema Management
Utilizes a robust migration system to handle schema updates as the platform evolves. This allows administrators to safely upgrade their instances while maintaining data integrity, ensuring that custom configurations and existing booking records remain compatible with newer versions of the codebase during the update cycle.
White-Label Scheduling Interface
Offers a clean, customizable UI that can be branded to match specific organizational requirements. Unlike SaaS platforms that force branding, Cal.diy allows for deep CSS and layout modifications, making it suitable for embedding directly into existing web applications or internal portals as a seamless scheduling component.
