Salesforce Flow Visual Comparison Tool for Summer ’26

The Summer ’26 release for Salesforce introduces significant enhancements to the Flow Builder, notably the addition of a Visual Comparison tool. This feature aims to streamline the process of understanding changes between different versions of a Salesforce Flow, a critical task for developers and administrators.

Visual Flow Comparison Tool

The Flow version comparison functionality, initially released in Winter ’26, allowed users to compare Flow versions in a tabular format. Summer ’26 elevates this capability with a dedicated Visual Comparison mode, presenting changes directly within the Flow canvas.

Accessing Visual Comparison

To utilize the Visual Comparison tool in an org running Summer ’26 or later:

1. Open a Salesforce Flow that has multiple saved versions.
2. In the top bar of Flow Builder, select the Flow version dropdown.
3. Scroll to the bottom of the versions list and click "Compare Versions."
4. Select another version of the Flow to compare against.
5. On the right side of the menu bar, click the new "Visual Comparison" button.

This action will switch the view from a tabular representation to the Flow canvas, overlaying visual indicators to highlight discrepancies.

Understanding Comparison Indicators

Once Visual Comparison is active, elements on the canvas will display colored tabs indicating the nature of the change:

• Blue Tab: Represents an element that has been updated. Clicking the element will reveal the specific modifications.
• Green Tab: Indicates an element that has been created. This element is new in the current version and did not exist in the prior version.
• Red Tab: Denotes an element that has been deleted. This element was present in the earlier version but is absent in the later version.
• Pink Tab: Signals a changed connector between two elements. This means a connection that previously existed is now broken or altered.

For instance, if a new element is inserted between two previously connected elements, the original elements will display pink tabs to indicate the disruption of their prior connection.

Transform Element Content Comparison

A notable addition accompanying the Visual Comparison mode is the ability to compare changes within a Transform element. This includes modifications to mappings, joins, and formulas defined within the Transform element.

This detailed comparison for Transform elements is available in both the new Visual Comparison mode and the legacy tabular view.

When examining a Transform element's changes, you can drill down into individual field mappings. Added details, such as modified formulas or new joins, will be highlighted in green, while removed components will be marked in red.

Benefits of Visual Comparison

For large or complex Flows, the Visual Comparison tool offers a significant advantage over the tabular view. Instead of sifting through a list of changes, developers can immediately pinpoint the location of modifications directly on the Flow canvas. This direct visual feedback dramatically accelerates the process of diagnosing and resolving issues, especially in environments with frequent or extensive Flow modifications.

Key Takeaways

• The Summer ’26 release introduces a Visual Comparison mode for Salesforce Flow.
• This tool displays changes (updates, creations, deletions, connector modifications) directly on the Flow canvas using color-coded tabs.
• The Transform element now supports detailed content comparison for mappings, joins, and formulas within both visual and tabular views.
• Visual Comparison significantly enhances debugging efficiency by allowing developers to locate changes contextually on the canvas.
