The most notable features are HTTP/2, [Let's Encrypt](https://letsencrypt.org) support, Virtual Hosts, TLS + SNI, and easy configuration with a [Caddyfile](https://caddyserver.com/docs/caddyfile). In development, you usually put one Caddyfile with each site. In production, Caddy serves HTTPS by default and manages all cryptographic assets for you.

That simple file enables compression, allows directory browsing (for folders without an index file), serves clean URLs, hosts a WebSocket echo server at /echo, logs requests to access.log, and adds the coveted `Access-Control-Allow-Origin: *` header for all responses from some API.

**Running as root:** We advise against this; use setcap instead, like so: `setcap cap_net_bind_service=+ep ./caddy` This will allow you to listen on ports < 1024 like 80 and 443.

Caddy was born out of the need for a "batteries-included" web server that runs anywhere and doesn't have to take its configuration with it. Caddy took inspiration from [spark](https://github.com/rif/spark), nginx, lighttpd, Websocketd, and Vagrant, and provides a pleasant mixture of features from each of them.
