Architecture Auto-Detection
Your Architecture, Mapped
and Diagrammed Automatically
Code Swan analyzes your codebase and surfaces its structural organization: domains, products, features, services, and team ownership. It generates a queryable catalog and C4 diagrams, updated on every scan. No manual diagramming, no documentation to maintain.
Architecture Docs Are Always Behind
A service is split. A team takes ownership of a new product area. A feature moves to a different domain. Each change requires someone to find the architecture document, update it, and ensure the rest of the team sees the new version. That rarely happens, and the diagram drifts further from reality every sprint.
Illustrative scenario
A new engineer asks to see the system architecture. They are pointed to a Confluence page last edited fourteen months ago. It shows eight services. The codebase has twenty-three. Three of the original eight no longer exist. There is no entry for the product features added during last year's migration.
Two Outputs from One Analysis
A Queryable Catalog, Domains, Products, Features, and Services
Code Swan surfaces the organizational structure of your software project: services mapped to their domains, products, and features; team ownership assigned; and relationships between components identified. The catalog is queryable by any dimension, domain, product, feature, owner, or service. It's delivered into your AI tools via MCP so any engineer or agent can ask "which services power the checkout feature?" and get an accurate answer from the real codebase.
C4 Architecture Diagrams, Generated Automatically
Code Swan generates architecture diagrams at three levels of the C4 model , no manual diagramming, no DSL to maintain, no diagram that goes stale.
System Context
Your software system in relation to its users and external dependencies. The 30,000-foot view that every stakeholder conversation starts from.
Container
The services, data stores, and messaging systems that make up your system, and how they communicate with each other.
Component
The internal structure and relationships within each service, the building blocks that make up each container.
Frequently Asked Questions
What is architecture auto-detection?
Architecture auto-detection is the automated identification of a software project's structural organization, its services, domains, products, features, team ownership, and relationships, derived directly from the codebase. The result is a living catalog and set of architecture diagrams that stay current as the project evolves, without any manual documentation effort.
What is the C4 model?
The C4 model is a widely-used framework for visualizing software architecture at four levels of abstraction: System Context (C1), Container (C2), Component (C3), and Code (C4). Code Swan automatically generates C1, C2, and C3 diagrams from your codebase, giving teams a complete multi-level view of their architecture without manual diagramming.
Does architecture auto-detection work with any type of software project?
Yes. Architecture auto-detection works across any software project, microservices platforms, modular monoliths, multi-repo setups, and single-repo projects. Code Swan identifies the structural characteristics of whatever it analyzes and produces consistent catalog and diagram output regardless of architectural style.
How do AI tools use the detected architecture?
Code Swan delivers the detected architecture, service catalog, domain and product boundaries, ownership, and relationships, directly into AI coding tools via MCP. Engineers can ask their AI assistant architecture questions and receive answers grounded in the real, current structure of their system, not in outdated documentation or training data.
