Structurizr

Your software architecture documentation hub; and software architecture diagrams as code

This single workspace version of Structurizr provides a way to quickly view diagrams, documentation, and architecture decision records.

(free; paid support packages available)

On-premises

We also have a version of Structurizr that can be run on your own infrastructure (local servers or cloud), providing the majority of the same features found in the cloud service.

(free; paid support packages available)

Cloud service

Our cloud service allows you to get started with Structurizr without needing to host and update software on your own servers.

(free and paid)

CLI

A command line utility designed to be used in conjunction with the Structurizr DSL, supporting pull/push via the web API and exports to a number of formats including PlantUML and Mermaid.

Diagrams as code 2.0

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 using Markdown or AsciiDoc.

Architecture decision records (ADRs)

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