Take Control of Your Network Traffic.
Nova test is a blazing-fast, lightweight, and incredibly intuitive MITM proxy built for modern Windows developers. Intercept, inspect, and debug network requests made by any desktop application in real-time.
Why Choose Nova test?
If you've ever wondered exactly which background app is eating your bandwidth, or needed to debug the API calls your favorite Electron app is making, Nova test is your ultimate tool. Unlike traditional, clunky network inspectors, we tell you exactly who is making the request.
System-Wide Interception
Zero-configuration required. Launch the app, and it automatically configures your Windows System Proxy to begin securely intercepting traffic instantly.
Process Resolution
Stop guessing. Nova test actively maps every single network request to its originating application. See exactly if chrome.exe or Spotify.exe is sending data.
Active App Filtering
Drowning in background noise? Use our intuitive dropdown filter to isolate and inspect traffic for only the specific desktop application you care about.
Smart Memory
Built to handle massive downloads. Payloads under 1MB are rendered instantly, while massive files are streamed to disk to prevent out-of-memory crashes.
Modern Aesthetics
Sleek Dark Mode built with Tailwind CSS, Virtualized Real-Time UI on React, beautiful typography and Radix UI primitives.
Privacy First
Operates 100% locally. Generates a secure Root CA on your device and never sends traffic to the cloud. Cleans up your proxy settings on exit.
