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.
