Model the Modular Structure of Your System

Component diagrams show the internal structure of a software system: the components, services, libraries and modules it is built from, and the interfaces they expose to each other.

They are perfect for communicating architecture to developers and stakeholders, planning module boundaries, and documenting service dependencies.

What You Can Model

Modular Architectures

Show how an application is decomposed into components, services and libraries.

Exposed Interfaces

Document the APIs and contracts each component provides and consumes.

Dependency Graphs

Visualize how components depend on each other and identify coupling.

Layered & Packaged

Organize components into packages or layers for a clear high-level view.
