NovaWire is a native HTTP/HTTPS debugging proxy for Windows that captures real network traffic, lets you inspect and rewrite requests and responses, replay calls, and generate OpenAPI specs directly from live exchanges.

What to expect from an ideal product
- NovaWire runs as a native Windows proxy, so you intercept live HTTP and HTTPS traffic without browser extensions or third-party runtimes slowing you down.
- You can rewrite request headers, query params, and response bodies on the fly, which means you test against mock data without touching your backend code.
- Captured traffic converts directly into OpenAPI specs inside the same window, cutting out the manual documentation step most teams skip anyway.
- NovaWire lets you replay any intercepted call with modified payloads, so reproducing a bug from production takes seconds instead of rebuilding it from scratch.
- Because everything runs locally on Windows with no cloud sync required, sensitive API tokens and credentials never leave your machine during debugging sessions.
