Flowchart Maker
Build a real flowchart: add shapes, drag them on a snapped grid, wire them together, and the connectors route around whatever sits between them. Export a PNG, copy Mermaid source, or paste Mermaid back in.
About this tool
Flowchart Maker is a small diagram editor written from scratch: an SVG canvas with snap-to-grid dragging, orthogonal connectors that step around nodes in their way, layering auto-layout, undo/redo, PNG export rendered at 2×, and two-way Mermaid flowchart TD support. Everything — including the PNG rasterising — happens in this browser tab, so nothing you draw is uploaded. If you paste hand-written Mermaid, only the common syntax above is understood; anything else is skipped and reported.
