A browser-based network reconnaissance toolkit. This project is a collection of my old projects — Numnet and Arpy — which I originally wrote about 4–5 years ago as standalone CLI tools. This time around, I rebuilt everything from scratch with a proper web UI and a unified interface.
Same ideas, new execution.
- Network Discovery — ARP scanning and ICMP ping sweeps to find live hosts on the local network
- Port Scanning — TCP connect scans with banner grabbing (quick, common, full, or custom port ranges)
- OS Detection — Fingerprinting via TTL analysis, port heuristics, and service banners
- ARP Spoofing — Man-in-the-middle positioning with automatic ARP table restoration on exit
- Live Network Graph — Interactive topology visualization powered by Cytoscape.js, with right-click context menus to scan, spoof, or inspect any node
- Real-Time Updates — Everything streams over WebSocket so the UI updates as hosts and ports are discovered
- Backend: Python, FastAPI, Scapy, SQLite
- Frontend: Vanilla JS, Cytoscape.js (no build step)
- Comms: WebSocket for real-time scan updates

python run.pyRequires admin/root privileges for ARP and ICMP operations.
