Deploy and Host Caddy on Railway

Caddy is a powerful yet simple, Go-based open-source web server. Written in a memory-safe language, it compiles to a single, static binary, making it easy to run Caddy practically anywhere, even in containers. Caddy obtains and renews TLS certificates automatically, staples OCSP responses, and even performs automatic HTTPS rewrites.

About Hosting Caddy

Hosting Caddy means running a web server that handles HTTP/HTTPS requests, manages TLS certificates, and serves content through its modular architecture. The server compiles to a single static binary requiring minimal system dependencies while handling automatic certificate provisioning and renewal. Production deployment typically involves configuring domain settings, managing Caddyfile configurations, and coordinating SSL certificate management across different environments. Railway streamlines Caddy deployment by providing container hosting for the static binary, managing domain configuration for automatic HTTPS, and handling the underlying infrastructure while Caddy manages certificate automation and web serving.

Common Use Cases

Static Website Hosting: Serve static websites with automatic HTTPS certificate management and renewal
Reverse Proxy Services: Handle dynamic reverse proxying for backend services and load balancing
Container Web Serving: Deploy lightweight web servers in containerized environments with minimal resource overhead

Dependencies for Caddy Hosting

The Railway template includes the required Caddy binary and container environment with pre-configured static file serving.
