incident_report.log

WARNING

500MB for HTTP requests

Postman ships Electron + Chromium to send a GET request. Your terminal can do it in 4MB.

Forced accounts & cloud sync

Your API keys shouldn't require a login. Work offline. Own your data.

Binary blobs in git

JSON collections don't diff, don't merge, and break in code review.

Separate test tooling

Newman, pytest, shell scripts. Why isn't testing built into the request file?
