Mermaid vs PlantUML vs Graphviz for Confluence: Which Diagram Tool to Choose

· 7 min read

Quick Answer

Mermaid, PlantUML, and Graphviz are the three most popular text-based diagramming languages. Mermaid is the easiest to learn and covers the widest range (29 diagram types). PlantUML excels at detailed UML with precise notation control. Graphviz is best for technical network and dependency graphs. Most Confluence teams should start with Mermaid and add Graphviz for network diagrams if needed.

What you'll learn
  1. The strengths and weaknesses of each tool
  2. Which diagram types each one supports
  3. How easy each is to learn and use
  4. A practical recommendation for Confluence teams

Text-based diagramming — writing a few lines of code that render into a diagram — is how modern teams keep diagrams in sync with their documentation. No more drawing boxes by hand in Visio, exporting screenshots, and pasting them into Confluence where they go stale. With text-based diagrams, you edit the source and the diagram redraws instantly.

But there are three major text-based diagramming languages, and they are not interchangeable. Each has different strengths, different syntax, and different ideal use cases. This guide compares Mermaid, PlantUML, and Graphviz so you can choose the right one (or combination) for your Confluence team.

Enhanced Markdown vs Other Confluence Markdown Apps — Feature Matrix

Developers write in Markdown. Confluence doesn't. Every engineering team that moves from GitHub wikis, README files, or Hugo docs to Confluence hits the same wall — the rich text editor feels slow, and there's no way to write in the format they already know.

Several marketplace apps bring Markdown to Confluence, but they take different approaches. Some embed Markdown as macros. Others import Markdown files. A few offer live editing. We built Enhanced Markdown for Confluence to give teams a full WYSIWYG Markdown editor with code highlighting, charts, UML diagrams, and table merging — all inside the Confluence page editor. In this post we compare it against every alternative.
