Key highlights of the appDiagrams as code: type Mermaid or paste it from any AI and see the diagram as you type. Flowcharts, sequence, Gantt and more
Code on the left, diagram on the right
The preview redraws while you type, so mistakes show up at once. Start from 12 examples, paste a mermaid block from Markdown as it is, and go back to an earlier version when you need to.
Diagrams that fit the page
Diagrams fit the page width and very wide ones scroll sideways. They also work in included pages, expand sections and tabs. If something can’t be drawn, the error box shows the exact line.
Open any diagram large, with zoom
One click opens a diagram large, with zoom and a 1:1 view. Download any diagram as SVG or PNG for slides, tickets or docs.
