LikeC4 is a modeling language (DSL) and toolchain for describing software architecture as code, inspired by the C4 Model and Structurizr DSL. It generates live, interactive diagrams from architecture models, with a CLI, VSCode extension, and embeddable React/Web Components.

Use cases

• visualize software architecture as code
• generate C4 diagrams from a DSL
• keep architecture diagrams up to date in git
• embed interactive architecture diagrams in docs or React apps
• validate architecture changes and catch drift
• expose architecture model to AI agents via MCP

When to choose

• you want architecture-as-code with versioned, reviewable diagrams
• you need customizable notation and nested architecture levels beyond standard C4
• you want diagrams embedded in docs, websites, or React apps
• your team collaborates on architecture via Git workflows

When to avoid

• you need drag-and-drop diagram editing rather than code-defined models
• you only need one-off ad-hoc diagrams without a maintained model
• you require full Structurizr compatibility or its specific tooling
