NetLeafy Scanner is a massively parallel IP/SNI discovery tool designed to identify working Cloudflare edge nodes and clean SNI domains. It uses a 2-stage verification process to validate both TLS handshakes and HTTP response codes, ensuring zero fake-positive results.
Note: Designed to work perfectly alongside the NetLeafy Web Tool. Scan, copy your results, and generate your optimized config instantly.
Capable of running up to 150 concurrent threads. Scans thousands of IP/SNI combinations in seconds without compromising accuracy.
Includes native support for termux-wake-lock and specialized low-RAM performance profiles to prevent crashes on Android devices.
Drops blocked, reset, or DPI-injected responses automatically. It strictly validates the HTTP code and total connect time to ensure the highest stability.
A fully automated sequence: Pings all IPs → Scans working pairs → Performs a 3-probe stability test → Outputs the absolute fastest results.
Prerequisites: Python 3.7+, cURL (pre-installed on most OS).
# Clone the repository
git clone https://github.com/Code-Leafy/NetLeafyScanner.git
# Navigate to the folder
cd NetLeafyScanner
# Launch the scanner
python3 scanner.py🖥️ OS Specific Instructions
Windows:
Install Python from python.org, then run python scanner.py in PowerShell or CMD.
Termux (Android):
pkg update && pkg install python curl git
python scanner.pyNetLeafy Scanner features a beautiful CLI menu. Choose a performance profile based on your hardware:
- 1 Low-End Mobile — 15 threads / 6s timeout
- 3 Desktop — 60 threads / 3s timeout
- 4 Server/High-End PC — 120 threads / 2s timeout
🚀 Config Optimization: After the scan, take your results to NetLeafy. Select the G2ray server option and paste your config there to complete your setup.
Results are auto-saved with timestamps to your Downloads folder (or current directory):
NetLeafyScanner/
├── last_scan.json # Cached results for stability checking
└── NetLeafy_auto_best.txt # Sorted results (IP | SNI | Latency)
📊 Scanner Database Stats

❓ FAQ & Troubleshooting
Why am I getting "cURL Requirement Failed"?
Ensure curl is in your system PATH. On Linux/Termux, run apt install curl. On Windows, recent versions have it built-in.
What is "Shecan Bypass Mode"? It uses specific DNS servers (178.22.122.101) to bypass regional restrictions during the SNI lookup phase.
