Caddy

Caddy is an open-source web server that automatically manages HTTPS certificates for your websites and applications. It is written in Go and is designed to be easy to configure using a simple file format called the Caddyfile. By default, it handles the complexities of TLS/SSL, meaning it automatically provisions and renews certificates from Let's Encrypt without requiring manual intervention. You can set it up by downloading the binary for your operating system, creating a basic Caddyfile that defines your domain and back-end service, and running the command to start the server.
