Flow create update and delete versus Workflow and Process Builder
Key Takeaway
Build new automation as a flow, because you can't create new workflow rules or processes. In a record-triggered flow, use "Fast Field Updates" to set fields on the triggering record and "Actions and Related Records" to create or delete related records, so an automation that does both needs one flow of each kind.
Workflow rules and Process Builder are older point-and-click tools that automate record changes. Both are now legacy features. Flow Builder combines what both of them do in one tool, so new automation that creates, updates, or deletes records is built as a flow. To pick the right tool for a scenario, you need to know what each tool can still do and which kind of record-triggered flow fits each job.
Where workflow rules and Process Builder stand
Starting in Winter '23, you can't create new workflow rules or processes. For any new automation, create a flow in Flow Builder. Salesforce strongly recommends Flow Builder over both older tools.
Existing workflow rules and processes aren't locked. You can still activate, deactivate, and edit them. Support for both ended on December 31, 2025, but existing processes continue to run after that date.
Flow Builder combines the capabilities of workflow rules and Process Builder in a single point-and-click tool, which makes it easier to build a triggered process.
