Traffic Diff
Overview
Traffic Diff compares two HTTP transactions side-by-side, visually highlighting differences in headers, body, status codes, and more. Quickly identify exactly what changed between two requests or responses.
Useful for comparing API responses before and after changes, verifying differences across environments (dev/staging/production), and contrasting normal vs. abnormal requests during bug investigation.
Comparison Items

Comparison Modes
Header Comparison
Headers are compared as key-value pairs and classified into three change types:
- Added: Newly added headers
- Removed: Deleted headers
- Modified: Headers with changed values for the same key
JSON Comparison
When bodies are JSON, structural comparison is performed. Changes are shown with JSON paths (e.g., .data.users[0].name), change types, and before/after values.
Text Comparison
Non-JSON text bodies are compared line-by-line, classified as additions, deletions, or unchanged.
Binary Comparison
Binary bodies show only size differences.
