🔍 Ever wanted to see your entire network — live — in one glance?
Meet **nettopo3** — 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.
🖧 **What it does:**
✅ Scans one or more subnets continuously — full /24 in under 15 seconds
✅ Visualizes all hosts as an interactive live graph — color-coded by OS and latency
✅ Detects Linux, Windows, macOS, Network Devices automatically via TTL + vendor
✅ Wi-Fi vs wired detection — via ping jitter analysis (no extra infrastructure needed)
✅ Latency rings — hosts arranged by response time around the gateway
✅ Pinned host panels — vendor, MAC, open ports, SSH banner, HTTP title, NetBIOS, SNMP
✅ Live diagnostic windows — Route, Ping, nmap, ARP, ifconf, netstat — up to 8 simultaneously
✅ Multi-subnet support — multiple CIDRs in one topology view
✅ Copy-to-clipboard output for tickets and documentation
⚙️ **Tech stack:**
🔹 **Go** — concurrent scanner (50 goroutines, fast + full-detail loops)
🔹 **C / SDL2** — hardware-accelerated live graph at 60 fps
🔹 **Bash** — launcher script
Built using the **mshell Workflow** platform — an innovative multi-language pipeline environment from Art2Dec SoftLab that orchestrates Go, C, Python, Bash and more in a single visual workflow.
🖥️ **Tested platforms:**
• Ubuntu 22.04 LTS / 24.04 LTS — x86_64
• Debian 12 (Bookworm) ARM64 — Raspberry Pi 4/5
• Debian 13 (Trixie) ARM64 — Raspberry Pi 4/5
Pre-built binaries for all platforms included — just copy, edit one line in run.sh, and go.
