Compare Production Curls from Postman & DevTools — Staging vs Prod Diff
How to compare two Production or staging curl requests copied from Chrome DevTools or Postman. Use Spoold curl Compare to diff headers, auth, and body—or paste into curl Online to Send a single request.
Staging works. Production doesn't. Diff the curls.
Capture both requests as curl from Chrome DevTools or Postman, then paste them into Spoold curl Compare. See host, header, auth, and body drift without eye-balling escaped shell lines. To run one command, use curl Online.

Pick the right Spoold curl tool
| Job | Tool |
|---|---|
| Diff staging vs Production | curl Compare |
| Paste → edit → Send one request | curl Online / HTTP Request |
| Deep inspect + history | curl Viewer |
| Turn curl into fetch / Axios | curl → code |
Copy as cURL from DevTools
- Open Network → find the failing request.
- Right-click → Copy → Copy as cURL (bash).
- Repeat for the working staging (or last-known-good) request.
- Paste both into curl Compare—or paste one into curl Online to Send.
Export from Postman
In Postman, open the request → code snippet → cURL. Export the Production environment request and the Staging twin. Spoold parses both so you can compare curl requests field-by-field—not as a noisy text dump.
What usually differs in Production
Host & base path
api.staging… vs api… — confirm only env changed.
Auth tokens
Bearer / API keys rotate; the structured auth row makes token drift obvious (redact before sharing).
Headers
Missing Idempotency-Key, wrong Content-Type, or stale Accept.
Body
One nested JSON field—pair with JSON Diff if bodies are large.
Workflow: compare, then re-send
- Diff the two curls in Compare until the delta is obvious.
- Redact secrets in the “good” curl if you will share it.
- Paste the fixed command into curl Online, tweak headers in the Inspector, and Send against a safe staging host.
- Confirm status / body before touching Production again.
Tip: redact before Slack
Replace Authorization values with REDACTED before screenshots. Comparison is local, but chat logs are not. Prefer staging tokens when using Send.
