Quickly build business processes and logic models with Mermaid syntax. Clearly express complex processes through nodes, decisions and connections, ideal for product design, system analysis and business mapping.
A flowchart is a diagrammatic representation of an algorithm, workflow, or process; it uses different types of boxes to represent various kinds of steps, with arrows connecting the steps.
Turn complex business steps into clear process paths, helping teams quickly understand task execution order and business logic.
Used to design approval, operations, production and other processes, clarifying owners, execution conditions and handling methods for each stage.
Show system running processes, decision conditions and data flows through process nodes, supporting development and technical design.
Visualize program execution, branch decisions and processing rules to help developers analyze and optimize code logic.
Break down project phases, task nodes and execution paths to make complex project plans more intuitive and easy to understand.
You can generate flowcharts by writing Mermaid code, pasting Mermaid code, AI generation, image recognition, code summary and more. You can also draw flowcharts using our built-in flowchart templates.
After entering Mermaid syntax, flowcharts are generated and previewed in real time, with support for custom flowchart styles and themes.
You can download flowcharts and save them locally. We support exporting flowcharts to PNG, PDF, SVG, JPG, Markdown and other formats, or clicking the “Share” button to share the link with others.
If you are not satisfied with the result, click the “Visual editing” button to edit the flowchart again in the ProcessOn editor.
A Mermaid flowchart is a flowchart tool generated from text-based syntax. You can quickly create business processes, operation steps and decision logic with simple code. With the ProcessOn Mermaid flowchart editor, users can generate well-structured flowcharts online without drawing manually.
Unlike traditional drag-and-drop flowcharts, Mermaid flowcharts generate diagrams in a code-driven way, making them more suitable for developers and technical teams to manage versions and maintain continuously.
Mermaid flowcharts are widely used in business process mapping, product requirement analysis, software development processes, system design and project management. They help teams visualize task flows and logical relationships.
Simply enter Mermaid flowchart syntax such as nodes, connectors and decision conditions, and the editor will automatically parse the code and generate the corresponding flowchart. It also supports automatic Mermaid flowchart generation through AI.
Yes. Completed Mermaid flowcharts can be exported to PNG, JPG, SVG, PDF, Markdown and other formats, making them convenient for technical documentation, proposal presentations and team collaboration.
