nginx vs. Unicorn vs. Kore

nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. According to Netcraft nginx served or proxied 30.46% of the top million busiest sites in Jan 2018.

Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both the the request and response in between Unicorn and slow clients.

Kore is an easy to use web application framework for writing scalable web APIs in C. Its main goals are security, scalability and allowing rapid development and deployment of such APIs. Because of this Kore is an ideal candidate for building robust, scalable and secure web things.
