Up to 50,000 characters of Mermaid code and 800 connections. PNG export up to 32 megapixels. Share links are limited to diagrams that compress to about 12,000 characters. Mermaid 11 syntax; no real-time collaboration or cloud storage.

Swimlanes are Mermaid subgraphs, one per role or department; arrows between them show hand-offs. The diagram is not a BPMN execution model and does not automate the workflow. Rendering uses the open-source Mermaid library in your browser with its strict security level, so links, scripts and HTML in labels are disabled. Drafts are saved in this browser only; share links store the compressed code in the part of the URL after #, which browsers do not send to the web server. Exports contain only what you drew.

Employee submits expense → Manager approves → Finance checks policy and pays, drawn in three swimlanes.
