Flamingo Commerce is an open source e-commerce framework written in Go that allows building headless commerce solutions or traditional monolithic e-commerce applications. It promotes clean architecture, performance, and flexibility. Flamingo Commerce uses domain-driven design principles like bounded contexts and ports & adapters to decouple components and allow different technologies and services to be connected through adapters. This makes the e-commerce solution highly scalable, maintainable and able to integrate with external systems.
