📱 App Network Debugger

Real-time HTTP/HTTPS & Mobile Analytics Inspector for iOS & Android

A lightweight, standalone desktop proxy and network debugging tool designed specifically for mobile developers. Capture, inspect, and analyze live HTTP/HTTPS traffic, WebSockets, and native binary analytics payloads (Firebase & Branch) in real-time.

✨ Key Features

⚡ Smart Analytics Inspector 📱 Zero-Config Mobile Proxy

• Firebase Native Protobuf Decoding: Automatically parses binary analytics payloads into human-readable events.
• E-Commerce & Items Breakdown: Inspect view_item, add_to_cart, begin_checkout with nested product items, SKU, price, and category.
• Hero Parameter Chips: Key metadata (Screen, Category, Location, Currency, Value) spotlighted at a glance.
• Real-time Event Search: Filter events instantly by name or parameter value. • Auto IP Detection: Automatically finds your computer's local LAN IP for seamless mobile proxy configuration.
• 1-Tap Certificate Setup: Scan a local QR code on your phone or visit http://mitm.it to install the SSL certificate.
• Pause Mode: Temporarily pause recording without disconnecting proxy forwarding, keeping your phone online.
• Persistent CA: Reuses a private per-installation CA so you don't have to reinstall certs across app restarts.

📦 HAR 1.2 Export & Replay 🛡️ Privacy & Local-First

• Standard HAR 1.2 Format: Export selected or all captured flows into .har archives.
• Tool Interoperability: Re-open exported archives in Chrome DevTools, Postman, or Charles.
• Session History: Automatically persists captured sessions locally in SQLite to review past debugging sessions.
• Full Fidelity: Preserves duplicate headers, query strings, Base64 payloads, timings, and WebSocket frames. • Automatic Redaction: Mask passwords, bearer tokens, cookies, and sensitive headers before displaying or exporting.
• 100% Local: No captured packets or mobile analytics are ever transmitted to any third-party cloud servers.
• Standalone Desktop App: Everything is bundled into a single desktop package—no separate Python or mitmproxy installations required.

⚡ Native Firebase Analytics Decoding

Automatically unpacks binary Protobuf streams into color-coded event cards, hero parameter chips, and structured e-commerce items.

🔍 How It Works

Traffic flows from the mobile device through App Network Debugger to the API server

Proxy Capture: Your mobile phone sends HTTP/HTTPS/WebSocket traffic through the local proxy server running on your computer.
Real-time Inspection: The desktop interface captures URLs, methods, headers, status codes, payload bodies, and timing in real time.
Analytics Engine: The built-in analyzer inspects binary Protobuf streams (Firebase Analytics / Google Analytics) and surfaces structured events into interactive cards.

[!TIP]

💡 Pro-Tip: Real-time Firebase Analytics Debugging on Mobile

By default, the Firebase Mobile SDK buffers events locally and flushes them in batches every 1 hour to save battery. To see events appear in real-time as you tap on the phone:

Android: Connect via USB and run:

bash
adb shell setprop debug.firebase.analytics.app <your.app.package.id>

iOS: Pass -FIRDebugEnabled in Xcode launch arguments.
Quick Flush: Simply swipe the app to the Background (Home screen); Firebase SDK will immediately flush its queued events to the desktop debugger!

🚀 5-Step Quick Start

Five-step onboarding: same Wi-Fi, start capture, set proxy, install certificate, inspect requests

Connect to Same Wi-Fi: Ensure your mobile device and computer are on the same Wi-Fi network.
Start Capture: Open App Network Debugger, choose LAN devices, and click Start capture.
Set Mobile Proxy: In your phone's Wi-Fi settings, set Proxy to Manual. Enter the Host / IP and Port (8080) shown on the desktop app.
Install Certificate: Click Certificate on desktop and scan the QR code (or open http://mitm.it in mobile Safari) to install the CA certificate.
- Step 4a (Install Profile): Open Settings → VPN & Device Management (or Profile Downloaded) → select mitmproxy → tap Install.
- Step 4b (Enable Full Trust): Open Settings → General → About → Certificate Trust Settings → toggle Enable Full Trust for Root Certificates for mitmproxy.
Inspect Live Traffic: Open the mobile app you want to test and watch requests and analytics stream in!

[!NOTE] Some applications ignore system proxies or implement SSL certificate pinning. This debugger is designed for authorized testing of your own applications and development builds.
