# What is Iris

**Iris** is a free, open-source web framework for [Go](https://go.dev), created by [Gerasimos Maropoulos](https://twitter.com/MakisMaropoulos). 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](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller) 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](https://grpc.io/), allowing developers to expose their gRPC services as REST APIs.

The source code of Iris is hosted on [GitHub ](https://github.com/kataras/iris)and licensed under the terms of [BSD 3-clause License](https://opensource.org/license/bsd-3-clause/), like the [Go project](https://github.com/golang/go) itself.
