Review on Cowboy by Maxwell Thomas

The most useful feature is that it supports multiple protocols, including WebSocket (which was not supported by previous versions).

I like how easy you can add new features to this service provider using custom modules or plugins available from their GitHub repository - even if they are third-party services! It's great for building RESTful APIs with authentication support out of box as well as running microservices over different ports/protocols without having any external dependencies such us nginx proxy servers etc., which makes things easier when implementing an API gateway solution where we want our customers use only one platform instead many others ones just because each vendor has its own proprietary setup procedures required before being integrated into your stack; also adding additional security measures becomes simpler than managing them manually yourself at every step along development process since there exist no more open source software solutions providing these functionalities yet. As mentioned above.
