Caddy

Caddy is a modern, open-source web server and reverse proxy written in Go, designed for simplicity, security, and automatic HTTPS via Let's Encrypt. It uses a declarative configuration format (Caddyfile or JSON) to manage web hosting, load balancing, and API gateway tasks with minimal setup. Its built-in features include HTTP/2, TLS certificate management, and extensibility through plugins.

Also known as: Caddy Server, Caddy Web Server, Caddyfile, Caddy Config, Caddy Proxy

Why learn Caddy?

Developers should learn Caddy for its ease of use in deploying secure web applications, as it automates HTTPS configuration and reduces manual SSL certificate management. It is ideal for small to medium projects, microservices architectures, and scenarios requiring quick setup with robust security defaults, such as static site hosting or API proxying.
