Pick FlowSimp when
You need a flowchart, decision tree, or process sketch in the browser and you do not already live in Visio files. Open the editor, draw, and export. See the other options on the free alternatives page.

Pick Visio when
Your team already shares .vsdx files, you need Visio’s stencil libraries, or the diagram has to stay inside Microsoft 365. FlowSimp does not import those files.
