SankeyMATIC review

SankeyMATIC turns manually entered flows into Sankey diagrams: charts where the width of each connection represents an amount moving between stages. You enter lines in the format “Source [Amount] Target,” then adjust the diagram’s appearance and export it as a PNG or SVG. The tool is suited to visualizing budgets, financial results, application processes, elections and other flows—not to managing the underlying data.

You can save the editable text state to return to later or compare versions. According to the pricing information, diagrams process locally in your browser. No account, email, extension, code or trial signup is required. The tool is free, and the pricing page lists no paid plans or monthly or annual charges. That makes it a low-commitment option if you need a chart, rather than another subscription to manage.

The appeal is straightforward: enter amounts as text, shape the diagram with interactive controls, and export a file. PNG works for a shareable image; SVG gives you a vector file for embedding or further editing in a vector graphics program. Saving the text state is useful when you want to revisit a chart without rebuilding its inputs from scratch.

• No purchase or signup decision: The tool is free, with no published paid tiers or add-on charges. You can start without handing over an email address.
• Two export formats: PNG and SVG cover raster images and vector workflows, and the feature description says PNG exports offer multiple sizes.
• A familiar format for sharing flows: Reddit posts show people using SankeyMATIC for personal budgets and job-search timelines. In one r/dataisbeautiful thread, a user shared a job-hunt diagram made with the tool.
• Local processing: The pricing information says diagrams are processed in-browser, a useful detail for people entering sensitive figures.

For occasional diagrams, the combination of editable text, exports and no subscription is the clearest selling point.

The main limit is one the pricing information leaves open: usage limits are not published. The tool is free, but the available details do not say how many diagrams you can make, whether any inputs or exports are capped, or whether large projects run into restrictions. There is no paid plan listed as a fallback if you do hit a limit.

SankeyMATIC also starts from flow data you enter yourself. The published feature information describes text input and diagram customization, not importing data from spreadsheets or connecting to analytics and finance platforms. If you need those workflows, check the tool before planning a migration around it.

And a clear chart is not the same as a complete financial analysis. An accountant in a Reddit discussion argued that common personal-finance flowcharts do not always make net income, expenses and profit easy to identify. That is a caveat about how people use Sankey diagrams, not evidence that SankeyMATIC miscalculates figures: treat it as a visualization tool and verify the underlying numbers separately.

SankeyMATIC costs $0 for the listed Free plan. The pricing details checked on November 7, 2026, list no paid tiers, monthly or annual billing prices, or feature add-ons—so there is no tier jump to budget for. Optional donations and sponsorships are mentioned, but they are not required payments for using the tool.

The free plan includes diagrams processed locally in your browser and requires no sign-up. The tool supports PNG and SVG export, along with saving the diagram’s editable text state. The catch is that usage limits are not published. We can’t confirm from the published pricing information whether there are caps on diagram size, exports, or frequency of use.

There’s no trial period or billing cycle to cancel, and no paid plan is listed. If you need documented usage caps or paid support coverage, the available pricing information doesn’t establish either. Treat the tool as free, but don’t assume unlimited use is guaranteed.

Moving a flow into SankeyMATIC looks relatively straightforward if you can express it as lines in the format “Source [Amount] Target.” The tool turns those entries into a diagram, and you can customize its appearance. The published material does not describe a bulk importer or integrations, so don’t assume existing charts can be transferred automatically.

To keep or move a finished diagram, SankeyMATIC offers PNG and SVG exports, plus a way to save the editable text state and resume later. That gives you image files for sharing and text for continued editing; the sources don’t promise that another tool can import the saved state. No sign-up is required, and diagrams process locally in the browser, according to the plan details.

The published published material includes no Reddit posts or comments, so we can’t responsibly say what users on Reddit report as reasons for leaving. Published usage limits and support coverage are also absent—possible reasons to look elsewhere if you need documented caps or team support.
