- Inspect headers, status codes, and bodies
- Filter logs by host, method, status, etc.
- Click to view full request/response details
- macOS-native SwiftUI interface
- Export logs to JSON, HAR, and more
- Generate QA tester reports
- Detect anomalies using ML
- Battery usage analysis
- Dev/test utility toolkit
| Who? | Why? |
|---|---|
| Developers | Debug REST APIs, inspect network calls |
| QA Testers | Verify API usage, generate reports |

Configure System Proxy
- System Settings → Network → Your Wi-Fi → Proxy → Enable Web Proxy (127.0.0.1:8080)
