How to use Flowchart Maker
- 1Click Add Node to drop boxes onto the canvas; drag them to position.
- 2Pick the node shape (rectangle, rounded, diamond for decisions, stadium for start/end) and edit its label.
- 3Use Connect mode: click the source node, then the target node, to draw an arrow (with an optional label).
- 4Export PNG or SVG — the SVG is deterministic, so the same canvas always regenerates the identical file.
Flowchart Maker FAQ
- How is this different from draw.io or Lucidchart?
- No account, no server, no upload. You build the flowchart in your browser and export it — that is the entire product. It is deliberately simpler: boxes, arrows, decisions, and clean exports rather than a full diagramming suite.
- Can I export to PNG and SVG?
- Yes — both. The SVG export is deterministic: the same canvas always produces the identical SVG file, which is handy for committing diagrams to a repository.
- Is there a node or file limit?
- No artificial limit. The interactive editor is designed for everyday-size flowcharts (dozens of nodes); the text-based Mermaid Editor handles larger graphs comfortably.
