About

Caddy is another well-known reverse proxy that serves sites over HTTPS by automatically obtaining and renewing TLS certificates. Unlike Nginx, whose dependencies are written in C, Caddy boasts greater memory safety guarantees because it was written in Go. This means that, while C is vulnerable to catastrophic memory bugs, Go is not affected by these security vulnerabilities. Caddy also has a plugin model that extends its functionality.
