What to expect from an ideal product

1. NovaWire lets you capture live HTTP/HTTPS traffic and replay any request with one click, so you can test backend changes without rebuilding the original call from scratch.
2. No scripts, no curl commands, no Postman collections to maintain. You capture the request in NovaWire and replay it directly from the same window.
3. Replaying captured calls lets you verify that a refactored endpoint still returns the same response structure, without touching the frontend or writing a single test.
4. NovaWire runs natively on Windows, so there is no Docker setup, no browser extension, and no configuration file to wrestle with before you can start replaying traffic.
5. When a backend change breaks something, you can isolate the exact request from the capture log, replay it in isolation, and confirm the fix before involving anyone else on the team.
