The Workflow Builder is a free online tool for creating visual process flow diagrams. Add Start, End, Process, and Decision nodes, connect them with directional arrows, and build complete workflow diagrams that document business processes, software development flows, or project plans. Export your diagrams as PNG images or JSON files.
Workflow diagrams help teams understand, standardize, and improve their procedures. Decision nodes create branching logic with Yes/No paths, making it easy to model approval processes, escalation paths, and conditional routing. The Auto Layout feature automatically arranges nodes into a clean structure, and the Fit View button adjusts the zoom to show your entire diagram.
Everything runs in your browser with no account required and no data sent to any server. For related visual planning tools, try the Mind Map Maker for brainstorming sessions, the Decision Tree Builder for structured decision analysis, or the ER Diagram Designer for database modeling.
