Features

Granitic is a Go framework for building web-services and micro-services. Your application will compile to a single small executable with an integrated web-server, so no external web-servers or application-servers are required.

Granitic is designed to be self-contained and does not have any downstream dependencies. Granitic is also designed to be flexible and configuration-led, so your application only contains the Granitic features you need.
