maybe try using caddyserver.com instead of nginx? It is also a go project, and has a very simple configuration syntax. The automatic SSLs feature is what made my try it in the first place.
Caddy is great! But has the absolutely insane default of logging all headers. Make sure you change that before you log auth headers
What features would you want in lazynginx, out of curiosity?
I personally would love a simple way to do a reverse proxy. It is not hard, but could be as easy as writing the hostname you want and what it points at.
Just a simpler interface for creating reverse proxies or static sites and also maybe do automatic SSL as a cherry on top. Basically, I want something like Nginx Proxy Manager, but more lightweight and terminal friendly.
