Hey everyone!

&#x200B;

I wanted to share PulseWire, a project I’ve been building to bridge the gap between low-level command line network tools and interactive visual diagnostics.

&#x200B;

It’s a real-time network traffic visualizer that tracks active TCP/UDP sockets, resolves them geographically, and lets you block them directly at the OS firewall with a single click.

&#x200B;

Here is what it looks like and what it can do:

&#x200B;

⚡ What does it do?

Interactive Geolocation Map: It listens to your machine's active network connections and plots them dynamically as connection arcs on a custom dark Leaflet map. Your home location glows green, and remote servers pulse cyan (TCP) or magenta (UDP).

Process Tracking: It doesn't just show you IPs; it identifies which local process is making the connection (e.g. chrome.exe, discord.exe, spotify.exe).

Instant Firewall Blocking: Click any host marker to inspect its intelligence (ASN, organization, country, city) and instantly block it. You can block the single IP, or block the entire ASN subnet range to prevent automatic reconnects.

Built-in Auto-Downloader: GeoIP translation requires databases. PulseWire has a built-in one-click downloader that fetches, extracts, and installs MaxMind GeoLite2 databases automatically so you don't have to fiddle with folder structures.

Cyberpunk CRT Design: Styled with a neon scanline aesthetic, dark panels, dynamic HUD metrics, and responsive micro-animations.

&#x200B;

🛡️ How is it built?

Backend: Built in Python using Flask and Flask-SocketIO. It uses psutil to inspect active socket descriptors in real-time.

Frontend: Vanilla JS, Canvas overlay (for bezier connection curves), Chart.js (for process and country stats HUDs), and Leaflet.

Native Firewall Hooking: On Windows, it binds to netsh advfirewall (with UAC auto-elevation) and on Linux it hooks into iptables.

Zero-Dependency Runner: I packaged everything using PyInstaller. You can download the single standalone pulsewire.exe, double-click it, and it will request elevation and open the web dashboard in your browser automatically—no Python installation needed.

💻 Deploy/Try it out:

You can run it in two ways:

&#x200B;

Standalone Binary: Download pulsewire.exe from the releases page, run it as Admin, and it will auto-download databases and start the dashboard.

From Source: Install requirements.txt and run python run.py (requires Administrator shell).

I'd love to hear your feedback, feature requests, or suggestions! Let me know if you run into any issues or have ideas on what to add next (e.g., traffic volume graphs, protocol filtering, etc.).

Go try it and let me know what do you think.
