SankeyFlow
The Sankey diagram maker built for the Mac
Write your flows as text, build them in a visual list, or paste a spreadsheet, and get a Sankey diagram. Show leftovers as Remainder boxes, then export PNG, PDF, or SVG. A native Mac app with no account; nothing leaves your Mac. $6.99.
Hi Product Hunt, I'm Jaime from Creixems Studio.
SankeyFlow turns a list of flows into a Sankey diagram: the chart that shows how a total splits and merges as it moves from one place to another. Budgets, energy use, website traffic, headcount, material flows — if a total divides into parts, it draws it.
It's a native Mac app, so there's no browser tab and no account. You can write flows as text, one line each (`Salary [3000] Budget`, which will feel familiar if you've used SankeyMATIC), build them in a drag-to-reorder list, or paste a spreadsheet. Then style it, choose a flow direction, and export a PNG, PDF, or clean SVG.
Version 1.1 shipped on October 8 with Remainder, a feature users asked for: when a box receives more than it passes on (or less), show the difference as a Remainder box, send it to a box you choose, or leave a gap. It also adds version history, tabs, and a refreshed look.
SankeyFlow runs entirely on your Mac and collects nothing. It's $6.99 on the Mac App Store and needs macOS 26 or later.
I'd love to hear what you'd chart with it, and what's missing.
