Difference Flow Designer vs Workflow

[rushi9499]

Flow is the modern, recommended tool for building automated processes in ServiceNow, featuring a low-code, visual interface with reusable actions and better integration capabilities. Workflow is the legacy tool, which is still supported but less intuitive and lacks the modern features like Flow Designer's integration spokes and advanced error handling.

Here’s a clearer and more easy-to-understand version of the difference between Flow Designer and Workflow (Legacy) in ServiceNow:

	Flow Designer (Flow)	Workflow (Legacy)
User Experience	Has a modern, drag-and-drop interface that is easy to use and visually clear. Great for low-code and no-code users.	Has an older interface that is more technical and script-heavy, making it harder for beginners.
Use Case	Best for new automation and integrations. Ideal for non-technical users or citizen developers who want to automate without coding.	Used for older or complex processes. Good when the required feature is not yet supported in Flow Designer (like some SLA timers).
Integrations	Provides easy integrations through IntegrationHub spokes, allowing simple connections with external systems.	Integrations are more manual and often need custom scripting to connect with other systems.
Development	Designed for both technical and non-technical users. Minimal scripting is needed.	Mostly for technical developers who are comfortable writing scripts and business logic.
Error Handling	Has built-in error handling tools like Try/Catch blocks, making it easier to manage failures.	Has limited error handling, often needing custom scripts to manage errors.
Recommendation	Recommended by ServiceNow for all new development, as it’s continuously updated with new features.	Considered a legacy tool — still works, but not recommended for new automations.
Complexity	Can handle complex logic, but sometimes simple tasks take more steps compared to Workflow.	Can manage very complex, script-heavy logic efficiently, but requires technical expertise.
