Port Light▲16I make this tool, a self-hosted dashboard, to show which host ports are taken, as a traffic-light grid. All the reason because I'm a home server enthusiast, but have a chaotic and terrible memory. It can aggregate ports from your different hosts and VPS as long as the network is reachable. And it merges three local sources into one grid: host listen tables, Docker API, and Compose files. As a beginner, I am open to everyone's comments, and if there are better similar tools, please tell me about them to help me refer to them for learning, thanks.

Hi HN, I built a small Linux CLI tool called witr (Why Is This Running?).

This is v0.1.0. It’s intentionally small and focused. Feedback, criticism, and edge cases are very welcome. Repo:…

Hi HN - I’m the developer of PingStalker, a macOS utility I built to see what’s really happening on the LAN/WLAN. I live in the CLI, but when it came to discovery and monitoring, I found it limiting. 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. I kept adding ways to…
