Cygwin vs Open Network Linux: What are the differences?

Developers describe Cygwin as "A way to run native Linux apps on Windows". It is a POSIX-compatible environment that runs natively on Microsoft Windows. Its goal is to allow programs of Unix-like systems to be recompiled and run natively on Windows with minimal source code modifications by providing them with the same underlying POSIX API they would expect in those systems. On the other hand, Open Network Linux is detailed as "An Operating System for Bare Metal Switches". It is an open-source, foundational platform software layer for next-generation, modular NOS architecture on open networking hardware It is a part of the Open Compute Project and is a component in a growing number of commercial NOS stacks and open source projects like CoRD & Stratum..

Cygwin and Open Network Linux belong to "Operating Systems" category of the tech stack.
