About caddy

Caddy is an extensible server platform that uses TLS by default, designed to serve HTTP/1.1, HTTP/2, and HTTP/3 traffic. It is most often used as an HTTPS server but functions as a platform for running Go applications through modular architecture.

Caddy emphasizes automatic HTTPS by default, supporting public certificates via ZeroSSL and Let's Encrypt, as well as a local CA for internal names and IPs. It is production-ready, scalable to hundreds of thousands of sites, and runs on any platform without external dependencies.
