Models as code

Structurizr builds upon "diagrams as code", allowing you to create multiple diagrams from a single model, using a number of tools and programming languages. This Structurizr DSL example creates two diagrams, based upon a single set of elements and relationships.

workspace {

    model {
        user = person "User"
        softwareSystem = softwareSystem "Software System" {
            webapp = container "Web Application" {
                user -> this "Uses"
            }
            container "Database" {
                webapp -> this "Reads from and writes to"
            }
        }
    }

    views {
        systemContext softwareSystem {
            include *
            autolayout lr
        }

        container softwareSystem {
            include *
            autolayout lr
        }

        theme default
    }

}

Designed for the C4 model

Structurizr is specifically designed to support the C4 model for visualising software architecture. Diagrams are interactive (e.g. zoom in/out), animatable, and embeddable. A diagram key/legend is automatically generated for each diagram too.

Diagram your cloud architecture

Use themes to help document your cloud architecture; with prebuilt themes for Amazon Web Services, Microsoft Azure, Google Cloud Platform, Oracle Cloud Infrastructure, and Kubernetes.

Documentation

Publish supplementary documentation (e.g. a "software guidebook", arc42, etc) using Markdown or AsciiDoc.

Architecture decision records (ADRs)

Publish architecture decision records (ADRs) that capture your significant design decisions.
