Netra Core

Netra Core is a lightweight, cross-platform desktop application designed to provide a secure, encrypted DNS tunnel while offering real-time network capacity benchmarking. It leverages Cloudflare's public infrastructure for high-accuracy speed tests without the need for accounts or rate limits.

🚀 Key Features

• 🔒 Secure DNS Tunneling: Automatically routes your system DNS through encrypted DoH (DNS over HTTPS) providers.
• ⚡ Live Capacity Benchmarking: Measures your actual network capacity (Mbps) with a high-accuracy, multi-sample speed test.
• 🌍 Cross-Platform: Native support for Windows, macOS, and Linux with automated system-level DNS management.
• 📈 Real-time IP Logging: Monitors and logs DNS queries in real-time to provide visibility into network activity.
• 🎨 Cyberpunk Aesthetic: A high-performance, dark-themed UI built for speed and clarity.
• 🛡️ Privacy First: No accounts, no tracking, and no rate limits. Results are served directly via global CDNs.

📥 Download & Install

The easiest way to use Netra Core is to download the pre-built binaries for your operating system.

🛠️ Development & Building from Source

If you are a developer and wish to contribute or build Netra yourself:

1. Clone the repository:

   git clone https://github.com/healer-op/Netra-Core.git
   cd Netra-Core

2. Install dependencies:

   npm install

3. Run in development mode:

   npm start

4. Build for production:

   # Windows
   npm run build:win
   # Linux
   npm run build:linux

   Note: macOS builds require a macOS environment.

⚙️ How it Works

1. Proxy: Netra starts a local DNS proxy that translates standard UDP DNS requests into encrypted HTTPS calls.
2. DNS Management:
   • Windows: Uses netsh to update interface DNS.
   • macOS: Uses networksetup for service-level updates.
   • Linux: Utilizes resolvectl (systemd) or nmcli (NetworkManager).
3. Speed Test: Performs 3-sample download and 2-sample upload measurements against Cloudflare's edge nodes to calculate true network capacity.
