The purpose of this list is to provide a listing of solutions available and commonly used by developers in the field in 2019 for back-end web development. I encourage everyone and anyone reading this list to also check out the site "https://github.com/kamranahmedse/developer-roadmap" as it has additional information on a logical order to run and use these apps as well as additional topics that are not software solutions, but concepts that are important to learn.
