If you’re learning Salesforce automation or you’ve recently started working on an existing Salesforce org, you’ve probably heard about three automation tools: Workflow Rules, Process Builder, and Flow Builder.
All three tools are used to automate business processes in Salesforce. They can perform actions automatically when a record is created or updated, or when it meets specific conditions.
However, they were introduced at different times and offer different levels of functionality. Before we compare them in detail, here’s the most important thing to know:
Salesforce has retired Workflow Rules and Process Builder. As of December 31, 2025, these tools are no longer supported for future development. Flow Builder is now Salesforce’s primary and recommended automation tool.
So, why is it still important to learn about Workflow Rules and Process Builder?
- Many Salesforce orgs still have existing Workflow Rules and Process Builder automations that continue to run.
- Salesforce certification exams may still reference these tools.
- Understanding the limitations of older automation tools helps you better understand and use Flow Builder.
- When troubleshooting a legacy Salesforce org, knowing how these tools work can help you identify and resolve issues more effectively.
Now, let’s compare Workflow Rules, Process Builder, and Flow Builder in detail.
