The overall best feature I’ve found in darkhttpd is that it is configured via command line arguments, so you can wrap the configuration of each one of your web servers into it’s runit/OpenRC service!
Running a static webserver will help you reduce overhead and lets you reduce the resource usage of your services.
You can easily install it by running:
In Void Linux:
# xbps-install -S darkhttpd
In Alpine Linux:
# apk add darkhttpd
