Best Diagram Tool for Confluence — Mermaid vs Excalidraw vs Graphviz
Looking for the best diagram tool for Confluence? Confluence has no built-in diagramming, so every team adds a Marketplace app — but the right choice depends entirely on what you draw and how you prefer to work. This guide compares the three strongest options — Mermaid Plus for Confluence, Excalidraw plus Whiteboards for Confluence, and Graphviz Charts for Confluence — so you can pick the diagram tool that fits your team instead of guessing.
For most Confluence teams, Mermaid Plus is the best diagram tool — it covers the widest range (29 diagram types), is the easiest to learn, and renders text into diagrams that version cleanly with your docs. Pick Excalidraw Plus if you need freehand whiteboarding and wireframes. Pick Graphviz Charts for dense network and dependency graphs. Many teams install more than one.
