Caddy is a powerful, extensible, enterprise-ready server platform that uses TLS by default. Everything you would require in your infrastructure, from TLS certificate renewals and OCSP stapling, to reverse proxying and ingress, Caddy simplifies it all. Its modular architecture lets you do more with just a single static binary that compiles for any platform.
Caddy is the only web server that uses HTTPS automatically and by default. It automatically renews TLS certificates, staples OCSP responses and more. Though used mostly as an HTTPS server, Caddy can be used to run Go applications, offering automated documentation, graceful on-line config changes via API and more to these apps.
Caddy is very extensible, with a powerful plugin system unlike any other web server.
