We used to primarily use nginx for our static web server and proxy in-front of Node.js. Now, we use Caddy. And we couldn't be happier.

Caddy is simpler on all fronts. Configuration is easier. Free HTTPS out of the box. Some fantastic plugins. And for the most part, it's fast.

Don't get me wrong, it's not lost on me that Nginx is actually a superior product.

But for the times when you don't need that extra performance, and complexity - take a look at Caddy.
