[Kawipiko's author here] Caddy, and Nginx, Apache, etc., are general purpose web servers that either serve content directly from the file-system or reverse proxy requests to other backends. Meanwhile Kawipiko has only one purpose: serve resources from an embedded key-value database, namely the venerable CDB <https://cr.yp.to/cdb.html https://cr.yp.to/cdb.html>. While general purpose web servers use open-(read+send)*-close syscalls (and other tricks such as `sendfile`) for each request, Kawipiko uses a single memory-mapped database for all requests, thus all the I/O is mediated (and cached) by the OS. Thus, one could say that Kawipiko serves a well defined niche, heavily optimizing for that particular use-case, meanwhile the other servers although can do lots of other things, they can't be optimized for any of those use-cases.
