Diagrams in seconds—not slide decks.
Diagram tool for open source maintainers
Great OSS projects reduce friction for newcomers. A clear diagram is one of the fastest ways to communicate intent.
The gap: READMEs age quickly. Without visuals, contributors misread boundaries and open duplicate issues or conflicting PRs.
MapDiagram helps you keep contributor docs visually current—update a map when structure changes, and link it from your contributing guide.
