c4-diagramming

What problem does it solve?

C4 Diagramming helps architects and engineers produce consistent four-level diagrams mapped to Artifact Pyramid layers, enabling clear communication of system structure from context to code.

Core Features & Use Cases

• Four-level mapping: System Context, Container, Component, and Code diagrams aligned with pyramid layers.
• Flexible export formats: Mermaid diagrams and Structurizr DSL exports for integration into docs and tooling.
• Reference-driven workflow: Quick access to architecture references (ADR/arc42) for integrated documentation and governance.
• Use Case: An architectural team creates a 4-diagram package to share a system's overview with executives, engineers, and operations.

Quick Start

Define the architecture in a C4 model and generate all four diagrams using the recommended exports.
