Network Sniper turns Chrome DevTools into a full local-first API client. Capture, edit, and Resend any request — headers, params, body — then see an instant diff: status code, latency, and line-level JSON changes. Auto-detects REST, GraphQL, and Form requests. Use {{variables}} to swap dev/staging/prod without saving real tokens, export standard HAR 1.2 archives, and work with zero telemetry — sensitive headers like Authorization and Cookie are masked by design, not convention.
