Work with nodes and relationships visually while retaining the diagram source.
Mermaidman
A visual environment for Mermaid diagrams that keeps source text at the center.
The portfolio describes visual editing, source round-trip, durable identities, and nested diagrams. Contact us to discuss current access and compatibility with your diagram workflow.
Edit the picture. Keep the source.
Diagram source is easy to version, but large graphs are difficult to understand and change through text alone. Mermaidman connects a visual editing surface to structured Mermaid source.
How the pieces connect.
Keep identity intact
Durable identities help connect an edited visual element with its source representation.
Navigate nested graphs
Break a complex diagram into nested structures without losing the relationship to the larger system.
Where it fits
Useful for people documenting workflows, architecture, or relationships who want visual editing and source-based collaboration.
What needs review
Source round-trip and durable identity are the important engineering boundaries. A useful review checks whether edits preserve graph meaning, not just whether a diagram looks right.
