\ud83d\udd0d Ever wanted to see your entire network \u2014 live \u2014 in one glance?<\/p>\n\n\n\n

Meet **nettopo3** \u2014 a real-time Network Topology Scanner built from scratch at Art2Dec SoftLab using Go, C\/SDL2, and Bash. No web server. No database. No agents on target hosts. Just run it and watch your network come alive.<\/p>\n\n\n\n

\ud83d\udda7 **What it does:**
\u2705 Scans one or more subnets continuously \u2014 full \/24 in under 15 seconds
\u2705 Visualizes all hosts as an interactive live graph \u2014 color-coded by OS and latency
\u2705 Detects Linux, Windows, macOS, Network Devices automatically via TTL + vendor
\u2705 Wi-Fi vs wired detection \u2014 via ping jitter analysis (no extra infrastructure needed)
\u2705 Latency rings \u2014 hosts arranged by response time around the gateway
\u2705 Pinned host panels \u2014 vendor, MAC, open ports, SSH banner, HTTP title, NetBIOS, SNMP
\u2705 Live diagnostic windows \u2014 Route, Ping, nmap, ARP, ifconf, netstat \u2014 up to 8 simultaneously
\u2705 Multi-subnet support \u2014 multiple CIDRs in one topology view
\u2705 Copy-to-clipboard output for tickets and documentation<\/p>\n\n\n\n

\u2699\ufe0f **Tech stack:**
\ud83d\udd39 **Go** \u2014 concurrent scanner (50 goroutines, fast + full-detail loops)
\ud83d\udd39 **C \/ SDL2** \u2014 hardware-accelerated live graph at 60 fps
\ud83d\udd39 **Bash** \u2014 launcher script<\/p>\n\n\n\n

Built using the **mshell Workflow** platform \u2014 an innovative multi-language pipeline environment from Art2Dec SoftLab that orchestrates Go, C, Python, Bash and more in a single visual workflow.<\/p>\n\n\n\n

\ud83d\udda5\ufe0f **Tested platforms:**
\u2022 Ubuntu 22.04 LTS \/ 24.04 LTS \u2014 x86_64
