Free BPMN Maker
Model business processes with BPMN 2.0 — swimlanes, gateways, events, and tasks. No signup, no install, fully free.
Free forever · no signup · no credit card · unlimited diagrams
BPMN (Business Process Model and Notation) is the global standard for documenting how work flows across people, systems, and departments. FreeDiagram generates BPMN 2.0 diagrams from plain-English descriptions — no modeling software required.
How to make a BPMN diagram
Describe your process in plain English
Type a sentence or two describing the process, the roles involved, and the key decision points. You do not need to know BPMN syntax — the AI handles the notation.
Generate the BPMN diagram
Click Generate and FreeDiagram produces a BPMN 2.0 diagram with swimlanes, tasks, gateways, and events laid out automatically.
Refine with follow-up prompts
Add a new lane, insert an error boundary event, or split a gateway — just type what you want changed and regenerate.
Export or share
Download the diagram as SVG or PNG, or copy the BPMN XML to import directly into Camunda, Activiti, or any BPMN-compatible tool.
About BPMN diagrams
Business Process Model and Notation (BPMN) 2.0 is published by the Object Management Group and is the universally recognized language for process documentation. It provides a precise, visual grammar — flow objects, connecting objects, swimlanes, and artifacts — that both business stakeholders and process engines can interpret without ambiguity.
BPMN diagrams are organized into pools and lanes that reflect organizational boundaries. Tasks represent units of work, gateways model decisions and parallel splits, and events mark significant moments such as process start, timer triggers, message receipt, and end states. This structure makes cross-team process mapping far clearer than informal flowcharts.
One of BPMN's most powerful properties is its dual audience: the same diagram that a business analyst presents to a department head can be exported as BPMN XML and imported into a workflow engine like Camunda or Flowable for execution. This bridges the gap between process design and process automation without a redraw.
FreeDiagram generates valid BPMN 2.0 notation from a natural-language description. You describe the process; the tool maps it to the correct BPMN elements. Use it to document as-is processes, design to-be workflows, or prototype automation candidates before committing to a workflow platform.
Frequently asked questions
What is BPMN and when should I use it?
BPMN (Business Process Model and Notation) is the ISO/IEC 19510 standard for process diagrams. Use it when you need to document workflows that cross team or system boundaries, prepare a process for automation, or communicate process logic to both business and technical audiences.
Does FreeDiagram produce valid BPMN 2.0?
Yes. The output follows BPMN 2.0 notation — swimlanes, start/end events, tasks, exclusive and parallel gateways. You can export the BPMN XML and import it into Camunda, Activiti, or other BPMN-compatible engines.
How do I model parallel steps in a BPMN diagram?
Ask for a parallel gateway in your prompt — for example, 'after approval, notify the requester and update the ERP system simultaneously'. FreeDiagram will place a parallel split gateway and rejoin the branches automatically.
Can I add swimlanes for multiple departments?
Yes. Mention the roles or departments in your description and FreeDiagram will create a pool with one lane per role. You can request additional lanes in follow-up prompts.
Is there a difference between a BPMN diagram and a flowchart?
Flowcharts are informal and have no single standard. BPMN is a formal standard with defined semantics for each symbol — gateways behave differently from decisions in a flowchart, and events carry precise trigger and result meanings. BPMN is preferred when the diagram may feed a process engine or needs to be unambiguous across teams.
