More details
Mermaid Diagrams lets you create flowcharts, sequence diagrams, class diagrams, ER diagrams, state diagrams, Gantt charts, pie charts and user journeys using plain text — right inside Confluence.
Why teams like it:
- Text-based. Diagrams are defined in Mermaid.js syntax, so they're fast to write or update and easy to maintain.
- Live preview. See exactly what you'll get before you save, with clear error messages if something doesn't parse.
- Starter templates. Flowchart, sequence, class, state, ER, Gantt, pie, and user journey examples get you going in seconds.
- Looks native. Automatically matches Confluence's light and dark themes.
- Secure by design. Diagrams render entirely in your browser — nothing is sent to a third-party server.
Use cases:
- Data models (ER diagrams)
- API and sequence flows
- Architecture and system diagrams
- Onboarding and process docs
- Sprint and project timelines
