FAQ

Frequently asked questions

Can it visualize large workflows?

Yes, but for workflows with a very large number of jobs (dozens or more), the diagram may become quite large and difficult to read. In such cases, consider visualizing smaller, logical chunks of your workflow.

Does it support dependencies other than "needs"?

Currently, the tool only visualizes job-level dependencies defined by the "needs" property. Individual steps within jobs are not visualized.

Is my YAML data secure?

Absolutely. All processing occurs locally in your browser. No data is sent to our servers, making it safe for private or enterprise workflow configurations.
