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](https://marketplace.atlassian.com/apps/1236814/mermaid-plus-for-confluence?hosting=cloud\&tab=overview), [Excalidraw plus Whiteboards for Confluence](https://marketplace.atlassian.com/apps/1237651/excalidraw-plus-whiteboards-for-confluence?hosting=cloud\&tab=overview), and [Graphviz Charts for Confluence](https://marketplace.atlassian.com/apps/1237380/graphviz-charts-for-confluence?hosting=cloud\&tab=overview) — so you can pick the diagram tool that fits your team instead of guessing.

Quick answer

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.

2. The strengths and trade-offs of Mermaid, Excalidraw, and Graphviz
