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.

Every team that adopts Jira diagrams hits the same moment: you discover Mermaid supports 29 diagram types, you get excited, and then you realize you have no idea which ones to actually use during a sprint. Most of them never get drawn. The diagrams that earn their keep are the ones that make a standup faster, an onboarding doc clearer, or a ticket unambiguous — and those are a small, repeatable subset.

This post is the workflow guide we wish we'd had: the four diagram types a sprint team actually uses, each with a real scenario and copy-paste syntax you can drop straight into a Jira issue. The full 29-type reference follows, so the same page works as both a sprint playbook and a complete catalog.

Every architecture review ends the same way: the team sketches a system on a whiteboard, someone takes a blurry phone photo, and the diagram is never seen again. The next sprint a new engineer joins, asks how the system fits together, and the whiteboard gets redrawn from memory — different every time.

The fix is to capture the architecture sketch on the ticket it describes, editable by anyone on the team, versioned with the issue. That's what Excalidraw Diagrams plus Whiteboards for Jira does: it adds a full drawing canvas to every Jira issue, with 229 bundled shape libraries and freehand drawing. The same experience is available in Confluence via Excalidraw plus Whiteboards for Confluence. This guide walks through running an architecture session that produces a saved, shareable diagram.

Developer teams use Confluence differently than marketing or HR. You document APIs, share architecture diagrams, write runbooks, and collaborate on code reviews. The default Confluence editor works, but it wasn't built for technical documentation.

This guide covers the best Confluence apps for developers in 2026, organized by use case. We built several of these apps at NGPILOT, so we'll be transparent about where our apps fit and where competitors offer better solutions.

Need diagram tools for Confluence without paying for a large team? NGPILOT's three diagramming apps — Mermaid Plus, Excalidraw Plus, and Graphviz Charts — are all free for up to 10 users. This guide compares them so you can pick the right free diagram plugin for your Confluence.

Adding diagrams to Confluence pages helps teams communicate architecture, processes, and workflows visually. This guide covers the three main approaches to creating diagrams in Confluence and helps you choose the right tool for your needs.

No, Confluence does not support Mermaid diagrams natively. There is no built-in macro or feature that renders Mermaid syntax in Confluence pages. To add Mermaid diagrams to Confluence, you need a Marketplace app.

This guide covers how to set up Mermaid in Confluence and which diagram types you can create.

Sequence diagrams are one of the most widely used diagram types in software documentation. They show exactly how participants -- users, services, databases, external APIs -- exchange messages over time. For Confluence teams, embedding sequence diagrams directly on wiki pages means architecture docs, API specifications, and incident post-mortems stay in one place instead of scattered across external tools.

Mermaid's text-based syntax makes sequence diagrams fast to write and easy to update, but the syntax has its own set of rules that can trip you up. This FAQ answers the questions Confluence users ask most often about building sequence diagrams with Mermaid, with expanded explanations, working code examples, and copy-paste templates you can drop straight into a Mermaid Plus macro.

When teams need to add diagrams to Confluence, two tools come up again and again: Excalidraw and draw.io (also known as diagrams.net). Both are popular Confluence diagram apps on the Atlassian Marketplace, but they take fundamentally different approaches to visual communication — and picking the wrong one wastes time and licensing budget.

The short version: for live whiteboarding, brainstorming, and freeform sketching, Excalidraw wins. For formal, finalized diagrams (UML, network topology, BPMN), draw.io is the better fit. Most teams end up needing both — and the rest of this post is the honest, feature-by-feature comparison so you can make the right call for your workflow.
