BPMN Viewer

The BPMN Viewer is a non-executable diagram renderer and validator for BPMN 2.0 diagrams expressed in XML or BPMN-compatible JSON. It is intended for developers, business analysts, QA engineers, and governance teams who need to visualize, validate, and share process models in headless or embedded environments.
It parses inputs, builds an internal graph of flow elements such as startEvent, task, gateway, endEvent and sequenceFlow, then computes a readable layout and renders the diagram to SVG. The focus is on presentation and structural correctness rather than execution semantics, with diagnostics to guide corrections.
The tool supports typical modeling patterns, including linear flows, parallel branches, and conditional paths, and provides deterministic coordinates for stable rendering across environments. It operates without requiring server interaction by default, enabling offline use and easy embedding in automation pipelines. Its outputs include a scalable diagram and a machine-readable diagnostic log for integration with documentation and governance workflows.
Typical use cases include in-code diagram previews during development, CI validation of BPMN artifacts, and lightweight documentation generation for process governance. The approach emphasizes accessibility of structural information and interoperability with other modeling tooling while remaining focused on visualization.
