PlantUML Diagrams

Create UML diagrams including class, sequence, and component diagrams with PlantUML text notation.

Claude Code Cursor Copilot

Overview

PlantUML is a versatile tool for creating UML diagrams from plain text descriptions. AI coding agents can generate comprehensive UML diagrams including class diagrams, sequence diagrams, activity diagrams, component diagrams, and deployment diagrams.

Agents can analyze object-oriented code to generate class diagrams with inheritance and composition relationships, trace method calls to create sequence diagrams, and map system architecture to component diagrams. PlantUML's text-based format ensures diagrams are easily maintainable and version-controlled.

PlantUML supports extensive customization through skinparam settings, themes, and preprocessor directives. Teams can standardize their technical documentation with consistent UML diagrams that AI agents can generate and update as the system design evolves.

Who Is This For?

Create sequence diagrams from API interactions
Build component diagrams for system architecture
Produce activity diagrams from workflow definitions
