Caddy is the ultimate web server anyone should be using. This is true for production as well as for local development. It is very fast, and by default obtains and renews SSL certificates automatically. This is useful for when you want to test certain website feature that is only allowed when they're accessed with HTTPS. You get free TLS for all your subdomains, and it does that in a scalable way.
