NetScan: Local Wi-Fi & Ethernet scanner. No ads, no account, no cloud

Hey Product Hunt! 👋 I'm Robin, a solo developer currently retraining into IT (networking & cybersecurity, TSSR certification in France). NetScan grew out of my own homelab — I kept wanting a quick, reliable way to see exactly what was connected to my network without opening a laptop or trusting a cloud-based tool with that data. Most existing network scanners either require an account, run on a subscription, or send data off-device. NetScan does everything locally: no account, no ads, no tracking — a one-time purchase instead of a subscription. It scans both Wi-Fi and Ethernet, identifies each device (IP, name, open ports), lets you rename/tag devices, keeps a scan history with CSV export, and can monitor in the background to notify you when a new device joins the network. Still actively improving it based on feedback — happy to answer any questions, and let me know what you'd want to see next! Free promo codes available for the first 20 people — comment or DM me
