structurizr
Eliminates hand-drawn architecture diagrams that drift from reality.
Structurizr is a 'models as code' tool for the C4 model: you write Structurizr DSL to define a single software architecture model and generate multiple diagrams from it. Created by the author of the C4 model and remains the reference implementation. Use it in the free online playground or run it locally with the pre-built Docker image. Note: standalone architecture tooling, not a Claude Code skill.
- Generate C4 context, container, and component diagrams from code definitions
- Export architecture as PlantUML, Mermaid, or interactive web views
- Version control architecture alongside codebase in Git
Eliminates hand-drawn architecture diagrams that drift from reality. Code-based C4 models stay in sync with actual system decisions and scale across multiple views.
Engineering teams documenting system architecture for onboarding, compliance, or cross-team alignment without maintaining separate diagram tools.
