Deploy and Host Caddy Backend Proxy on Railway

Caddy Backend Proxy is a minimal, production-ready reverse proxy built with Caddy. It forwards incoming HTTP traffic to a private backend service using Railway’s internal network. The proxy is framework-agnostic and works with any HTTP backend such as Django, FastAPI, Node.js, Go, or Rails, while Railway handles HTTPS and networking.

About Hosting Caddy Backend Proxy

Hosting Caddy Backend Proxy on Railway is straightforward and requires minimal configuration. The proxy runs as a lightweight container that listens on Railway’s assigned port and forwards requests to a backend service via a private Railway domain. You only need to specify the backend host and port using environment variables. Railway manages deployment, scaling, networking, and TLS termination, allowing Caddy to focus purely on reverse proxy responsibilities without additional plugins or custom builds.

Common Use Cases

Exposing a private backend service behind a public endpoint
Adding a reverse proxy in front of an existing API or web service
Centralizing routing and security headers for backend services
Acting as a lightweight gateway between multiple Railway services

Dependencies for Caddy Backend Proxy Hosting

Railway – for container hosting, networking, and TLS
