Compare two sets of HTTP headers. Spot added, removed, and changed entries at a glance — perfect for debugging CDN, cache, or API regressions.
| Status | Header | A | B |
|---|
Paste raw header blocks as you'd see them in DevTools or a curl -i response. Lines like Header-Name: value. HTTP status lines (HTTP/1.1 200 OK) are ignored automatically. Repeated headers (like Set-Cookie) are preserved and compared as multi-value.
