NetScanner - HTTP Catcher

Capture HTTP/HTTPS traffic on iPhone with request analysis, replay, rewrite debugging, HAR export, and essential developer tools.

NetScanner is a native iPhone network debugging tool built for developers, testers, security researchers, and advanced users who need to inspect HTTP and HTTPS traffic directly on device. It is designed to make mobile traffic inspection faster, clearer, and more practical for day-to-day debugging work.

With NetScanner, you can capture requests and responses in real time, review key request details, manage HTTPS certificate setup, and keep your debugging workflow on the device. The app focuses on practical inspection and troubleshooting, while also providing utilities that help speed up API testing and request analysis.

1. Real-time traffic inspection
   Capture HTTP and HTTPS traffic on iPhone and review requests, responses, status codes, timing, headers, body content, and other key details in one place.

2. HTTPS setup and debugging workflow
   Follow guided certificate setup steps, inspect request and response data more clearly, and use the app as a daily debugging companion for interface analysis and issue investigation.

3. Request analysis and editing
   Review request content in detail, replay requests, edit parameters, and quickly verify API behavior during testing and troubleshooting.

4. Rewrite rules and local debugging
   Apply rewrite rules for request or response debugging, adjust traffic behavior, and support more flexible development and verification scenarios.

5. Session history and HAR export
   Keep captured sessions organized, review previous traffic records, and export HAR files when you need to share or archive debugging results.

6. Built-in developer utilities
   Use integrated tools such as JSON formatting, URL encode/decode, Base64 encode/decode, regex testing, hash generation, and timestamp conversion without leaving the app.

Captured traffic and debugging data stay on device unless you explicitly choose to export or share them.
