Iris is a free, open-source web framework for Go, created by Gerasimos Maropoulos. It enables back-end developers to build modern web applications with high performance and low overhead.

Iris is the only Go module that offers first-class support for the model-view-controller MVC architectural pattern, which helps to organize the code and separate the concerns of different components. Iris can also be used as a web port for gRPC, allowing developers to expose their gRPC services as REST APIs.

The source code of Iris is hosted on GitHub and licensed under the terms of BSD 3-clause License, like the Go project itself.
