The Basics

Structurizr is a diagram generation tool created by Simon Brown, the creator of the C4 Model. The tool’s primary focus is the rapid generation of several diagrams with the same components. Maybe Simon was tired of diagramming tools that make you repeat yourself? If so, I share the sentiment.

It’s free for most use cases.

Primary Use Cases

Creation of architectural diagrams
Capture architecture decisions
Diagram review
Saving time!

When to Use Structurizr?

When you need to create a diagram quickly, Structurizr is the tool for you. It’s a great tool for capturing architecture decisions and sharing them with your team.

Diagrams

Building diagrams can be very tedious, and Structurizr addresses this tedium. A typical workflow in Structurizr looks like this.

Add diagram elements
Create relationships
Layout your diagram
Download your diagrams

The CLI

Edit diagrams using the Structurizr command-line interface. You can follow these steps to edit your workspace if you’re on macOS.

# Install docker or some other docker-like app

cd /tmp
wget -P /tmp https://raw.githubusercontent.com/structurizr/examples/main/dsl/getting-started/workspace.dsl
docker pull structurizr/lite
docker run -it --rm -p 8080:8080 -v /tmp:/usr/local/structurizr structurizr/lite
open http://localhost:8080/ # Start editing!

# Update /tmp with your preferred directory

Structurize Your Workspace

I use Structurizr Lite to create diagrams with code. I’ve found a way to reuse models using this method. Reusing models keeps the management of links to component details simple.

workspace "Reuse Models" "Demonstrate Model Reuse" {

    model {
        customer = person "Customer" "Customer" "Customer"
        website = softwareSystem "Website" "Website" "Website"

        system1 = softwareSystem "system1" "" "" {
            rel1 = customer -&gt; website "Relationship scoped to system1"
        }


        system2 = softwareSystem "system2" "" ""  {
            rel2 = website -&gt; customer "Relationship scoped to system2"
        }
    }

    views {
        systemContext system1 {
            include customer
            include website
            exclude rel2
            autoLayout
        }

        systemContext system2 {
            include customer
            include website
            exclude rel1
            autoLayout

    }
}
