# Deploy and Host Cal.com on Railway

Cal.com (formerly Calendso) is the open-source Calendly successor. Scheduling infrastructure for absolutely everyone. You are in charge of your own data, workflow, and appearance.

## About Hosting Cal.com

Calendly and other scheduling tools are awesome. They made our lives massively easier. We're using them for business meetings, seminars, yoga classes, and even calls with our families. However, most tools are very limited in terms of control and customization. That's where Cal.com comes in. Self-hosted or hosted by us. White-label by design. API-driven and ready to be deployed on your own domain. Full control of your events and data.

Cal.com runs as a Next.js application with a database backend, requiring calendar integration management, email notification systems, and webhook handling for appointment workflows. You'll need to manage OAuth credentials for calendar providers, configure SMTP settings for notifications, and handle timezone calculations across users.
