What is Caddy?
Caddy is an open-source web server written in Go, recognized for its automatic HTTPS capabilities and straightforward configuration. It is designed to be enterprise-ready, providing a reliable foundation for serving websites and applications. Developers, system administrators, and organizations use Caddy to deploy and manage their web services with built-in security. Users configure Caddy with a simplified, human-friendly Caddyfile or a programmable JSON format to serve their websites. Caddy automatically obtains and renews TLS certificates for all sites, providing HTTPS by default. It also supports on-demand TLS for custom domains, allowing it to dynamically provision certificates and manage TLS at scale for many sites.
