Overview

A locally-run web application that discovers, monitors, and analyzes every device on your home or office network in real time. Combines a Django REST backend powered by Scapy for raw packet operations with a Next.js / React frontend — no cloud service required.

Key Features

ARP-based device discovery — IP, MAC, hostname, vendor, and OS fingerprinting

TCP SYN port scanning to identify running services and flag risky open ports

Live packet capture streamed to the browser via Server-Sent Events (SSE)

DNS monitoring — extracts queries from UDP port-53 packets per device

Interactive force-directed network topology graph

Dashboard with device count, protocol breakdown, top domains, and bandwidth charts

Security risk scoring based on open ports, traffic anomalies, and device hygiene

GeoIP traffic mapping using MaxMind GeoLite2

Per-device and aggregate bandwidth monitoring with configurable time windows

Visual traceroute showing each hop with RTT

Scheduled automatic scans via APScheduler

CSV/PDF data export and one-click data flush

Detailed Description

NetScope gives you full visibility into your local network without touching the cloud. ARP-scan your subnet to find every connected device, run port scans to flag risky services, and watch live traffic flow through an interactive topology graph — all streamed in real time via SSE. The security report scores your network's risk posture, while DNS monitoring shows exactly which domains each device is talking to. Built with Scapy for raw packet operations and a clean Next.js dashboard, it turns your browser into a network operations center.
