Deploy and Host Cal.com on Railway

Cal.com is an open-source scheduling infrastructure platform that lets individuals and teams manage bookings, appointments, and meetings. It serves as a self-hostable alternative to Calendly, giving you full control over your scheduling data and workflows.

About Hosting Cal.com

Cal.com is a Next.js application that requires a PostgreSQL database for storing users, bookings, event types, and availability. Hosting it involves configuring database connection variables, a NEXTAUTH_SECRET for session management, and a NEXTAUTH_URL pointing to your public deployment URL. Email (SMTP) configuration is needed for booking confirmation notifications. Optional integrations with Google Calendar, Zoom, Stripe, and other providers are enabled via additional environment variables post-deploy.

Common Use Cases

Allowing clients or teammates to self-schedule meetings based on real-time availability
Embedding a booking widget into a personal or business website
Managing multi-user team scheduling with round-robin or collective event types
