Flamingo is a high productivity go based framework for rapidly building fast and pluggable web projects. It is used to build scalable and maintainable (web)applications.
Go as simple, powerful and typesafe language is great to implement and scale serverside logic. Flamingo has a clean architecture with clear dependencies in mind and offers a typical features and support for nowadays web applications:
Flamingo itself does not contain ORM Mapper or libraries - instead it emphasizes "ports and adapters" architecture - so that you have a technology free (domain) model and any possible (and replaceable) persistence behind it. That makes Flamingo useful to build microservices and applications - especially to build "frontends" or portals that require interaction with other (micro) services in a distributed architecture. When sticking to the architectural recommendation, you can build modular applications with replaceable adapters that gives you independent testability.
With "Flamingo Commerce" there is an additional active projects that offer rich and flexible features to build modern e-commerce applications.
