C4 model architecture diagrams with PlantUML
PlantUML macro package for drawing C4 model software architecture diagrams as code.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.
Choose it when you want a current PlantUML macro library that also bundles C4 plus cloud-provider icon sets together.
A set of PlantUML libraries and a NPM cli tool to design diagrams which focus on several technologies/approaches: Amazon Web Services (AWS), Azure, Google Cloud Platform (GCP), C4 Model or even EventStorming and more.
Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
Choose it when you work in .NET and want to define C4 models as typed C# code rather than writing PlantUML macros.
C4Sharp (C4S) is a .net library for building C4 Model diagrams.
Choose it when you want a structured data model to maintain architecture and generate C4/UML diagrams from one source.
Overarch provides a data model for the holistic description of a software system, opening multiple use cases on the model data. Supports C4 and UML diagram generation with PlantUML.
Choose it when you model architecture in PHP using Structurizr and want diagrams generated from that model.

Choose it when you prefer Structurizr DSL plus a command-line renderer over hand-maintained PlantUML macros.
A command line utility for Structurizr.
Does the same job, but ships as an app. Useful to a person, not swappable into a codebase.
Choose it when you want a generated documentation site from Structurizr DSL instead of manually maintaining C4 PlantUML diagrams.

These projects were analysed and named C4-PlantUML among their alternatives. The relationship is not symmetric — how C4-PlantUML rates them is a separate judgement, made when C4-PlantUML is analysed in its own right.
calls C4-PlantUML “when you are already on PlantUML and only need C4 diagrams, not an agent/model tool”
