Deploying Cal.com Open-Source Calendly Alternative on Ubuntu 24.04

Cal.com is an open-source scheduling platform (a self-hosted alternative to Calendly) that handles bookings, event types, and calendar integrations on infrastructure you control. This guide deploys Cal.com with a PostgreSQL backend using Docker Compose, with Traefik handling automatic HTTPS. By the end, you'll have Cal.com serving bookings securely at your domain.
