I'm building this for myself after not being able to find anything useful enough for me (GoAccess [0] gets very close, but it doesn't have a nice HTML output with graphs I'd like, and it's hard to analyze substantial amounts of requests/data).
If there's anyone interested in trying something like this (or you know of a better tool), please reach out (you can find my email in my website, which is in my profile, or just `me[at][my username].com`).
Oh, and because caddy might mean different things to different people, I'm talking about the amazing web server [1].
