Original (A)

Changed (B)

💡 A structural diff (not line-by-line): it walks both objects and reports exactly which paths were added, removed, or changed — even deep inside nested objects and arrays. Everything runs in your browser.

API responses tips

🔌

Paste a response from before and after a change to spot exactly which fields differ.

🧭

Each difference shows its full path, so you can find it instantly in the payload.

🧹

Formatting and key order are ignored — only real value differences are reported.

🔒

Responses are compared in your browser — never uploaded.
