Excalidraw Architecture & Sequence Diagrams for Confluence brings Graphviz to Confluence: write architecture graphs in Graphviz DOT and sequence diagrams in Mermaid on Confluence pages, then sketch around them on an Excalidraw whiteboard — for design docs and runbooks.

Architecture graphs in the design doc
List components and dependencies in Graphviz DOT and get a laid-out graph in the page, then mark the fix or the open question by hand.
Runbooks and flows from plain text
Describe a decision flow in a few lines of DOT — or a sequence diagram in Mermaid — and the diagram follows every change to the text.
Design docs that stay correct
Annotate in the editor, keep the last 10 versions, never overwrite a colleague’s save, and export the page to PDF or Word with the diagram in it.
Also included
- Macro, space page and global page — a diagram per macro, the space’s diagrams, every scene on the site.
- PDF and Word export of the page includes the diagram.
- Built-in editors — Graphviz, Mermaid, LaTeX Math, Vega-Lite, WaveDrom; the source of each stays editable.
- Shared scenes and templates — one diagram on many pages, or a new one from a copy.
- Version history — the last 10 versions; conflict-safe saving with merge.
- Over 200 shape libraries inside the app, light and dark themes, non-Latin scripts.
Runs on Atlassian
Built on Atlassian Forge: scenes are stored inside your Atlassian site, rendered in your browser, and the app makes no external calls. Anyone who can edit a page can change its diagram. See the privacy policy.

Frequently asked questions
How do I use Graphviz in Confluence?
Install the app, edit the page, type /Excalidraw Graphviz and press Create diagram. In the editor, Insert → Graphviz takes DOT source with a live preview and lays the graph out automatically.
Can I edit a Graphviz diagram after inserting it?
Yes. The Graphviz source is stored with the diagram; choose Update, pick the diagram and change the text. The diagram keeps its place and scale in the scene.
Which diagram languages are included?
All of them in one app: Graphviz, Mermaid, LaTeX Math, Vega-Lite, WaveDrom, plus Excalidraw's own hand-drawn shapes and over 200 shape libraries.
What happens if two people save the same diagram?
Nothing is overwritten. The second person's changes stay in the editor, and they can merge them with the latest version, reload it, or save theirs as a copy. The last 10 versions are kept.
Does the app send diagrams to an external server?
No. Scenes are stored in the app's Forge storage inside your Atlassian site and rendered in your browser; all renderers ship inside the app.
What happens to the diagram when I copy a page?
The copy gets its own copy of the diagram, so editing it never changes the original. To show the same diagram on many pages, choose a shared scene in the macro settings.
Is the diagram in PDF and Word exports?
Yes. Exporting the page includes the diagram as it is shown on the page.
What permissions does the app ask for?
Only to read spaces and pages and to use its own storage. Changing a diagram on a page needs your permission to edit that page.
Where are my diagrams stored?
In the app's Forge storage inside your Atlassian site — scenes, images and the text sources. Nothing is stored with Simplify.
How much does it cost?
Free for up to 10 users; larger sites pay per user on the Atlassian Marketplace, with a free trial.
