Business Rules Visualizer

Visualize business rules easily in ServiceNow. Business Rules Visualizer brings a clear, interactive React Flow diagram to your instance, showing exactly how and when your business rules execute—built with React, TypeScript, and ServiceNow Fluent SDK.

Why Use This?

Understanding the execution order of Business Rules on a table can be a headache: clicking through lists, checking execution orders, and mentally mapping out Before, After, Async, and Display rules. This tool visualizes the entire pipeline.

Key Benefits:

• Visual Pipelines: See all rules for a table split into Record Write (Before, After, Async) and Form Load (Display) pipelines.
• Execution Sequencing: Rules are sorted by order and connected with sequential edges to communicate execution sequencing clearly.
• Inheritance Visibility: Instantly spot inherited rules with dashed amber borders and clear badges showing the ancestor table.
• Interactive Details: Click any rule to slide in a detail panel showing metadata, conditions, and the full script content.
• Smart Search: Autocomplete combobox for table search with live filtering and recent tables history.
