Model architecture using the C4 framework by creating C1 Context views for scope, C2 Container views for runtime boundaries, and C3 Component views for internal modules. This structured design workflow produces consistent, stakeholder-friendly diagrams from Context to Code.

Validate C4 diagrams with LikeC4 syntax by running the validation workflow using the command line tool. This process checks your models against formal C4 checklists and LikeC4 syntax rules, allowing you to iterate until all validation checks pass.

You need C4 deployment and dynamic diagrams to illustrate infrastructure mappings and runtime interactions for complex systems. These views capture infrastructure boundaries and runtime workflows, complementing the core C1 to C3 views to communicate structure to stakeholders.

You can use C4 modeling for projects of any size needing C1, C2, or C3 views. It is applicable to small architectures by creating a single C1 Context view and adding C2 Container views only as needed to define major runtime boundaries.

The best way to capture system scope and external actors in a C4 model is by creating a C1 Context view. This view defines the system boundaries and identifies all external actors, establishing a consistent foundation for subsequent container and component diagrams.

Use LikeC4 for C4 architecture modeling to validate models against formal checklists and specific syntax rules. It supports a structured design workflow to produce consistent, stakeholder-friendly diagrams from Context to Code, ensuring your architectural views remain accurate.
