Create a Mermaid diagram and export (PNG, SVG, Excalidraw)
Write the diagram as code (Mermaid) and see the result live: flowcharts, sequence, class and more. Download it as an image (PNG or SVG) or convert it to an editable Excalidraw file — the bridge from code to drawing. Great for documentation, tickets and presentations. Everything happens on your device; nothing is sent to any server.
Start with flowchart, sequenceDiagram, classDiagram, gantt, pie, mindmap…
Live preview
Write a diagram to see the preview.
The diagram is generated on your device. The Excalidraw file opens in excalidraw.com or the app for you to edit. Flowchart, sequence, class, ER and state diagrams come out as editable shapes; the other types (gantt, pie, mindmap…) go in as a single image inside the file.
