Diff

Compare two HTTP requests or responses with the Proxyman Diff tool, side by side or unified, including the URL, headers, status code, and body.

1. What's it?​

When you use Proxyman, you may need to find the differences between requests or responses. The Diff tool helps you:

  • Diff two requests or responses, including the URL, method, status code, headers, and text-based body.
  • Show the diff side by side or unified.
  • Use a light or dark theme.
  • Export as a unified diff file.
  • Open the diff in 3rd-party apps, such as FileMerge.
  • Highlight and add comments.

This feature is only available for macOS 11.2 and later.

2. How to use it?​

  1. Select your requests on the main table view.
  2. Right-click -> Tools -> Add to Diff Pool… (or press ⌘Y)
  3. In the Diff window, select the Left and Right requests.
  4. Proxyman performs the diff and displays it.

You can open the Diff window at any time from the Diff menu -> Open Diff View… (⌥⌘Y).
