An ultra-light-weight tool to quickly test your ping▲96
Howdy HN! I find myself testing my ping from time to time, especially when my internet seems wonky while WFH.

So I built a GUI that brings my favorite tools together in one place. PingStalker started because I wanted to know if something on the network was scanning my machine. I also wanted quick access to core details—external IP, Wi-Fi data, and local topology. Then I wanted more: fast, reliable scans using ARP tables and ICMP. As a Wi-Fi engineer, I couldn’t stop there.
