I have run it in so many different scenarios, both professionally and personally, its crazy. Nginx has never failed me, literally. My homeserver is quite limited but nginx has a very small footprint, it performs beautifully well and it satisfies all my hosting, proxying, redirecting and streaming needs.
It works for modern and legacy applications, custom code, webhosting, supports all the modern features and its configuration is very easy with literal thousandsof examples available online.
Apache probably can do all that but I hate how unintuitive its configuration is to me personally. HAproxy cant do half the stuff nginx does.
As for caddy Ive heard of it but never really used it. What does it offer that nginx doesnt?
