I'm wondering what those features are? What are the top 2 features you use most that are missing in Caddy? I used to go to nginx by default, but I switched to Caddy recently and I'm wondering what hurdles I'm setting up for myself.

Really? My experience was the opposite. I found everything I needed intheir docs rather quickly.

I guess it's true they don't have as many basic examples as nginx, but I'd take their lack of example over the mess an nginx config can become any day.
