Netstat Cat 0.1.0, developed by Xueshi Qiao, is a lightweight desktop utility designed to give Windows and macOS users a real-time view of every active TCP and UDP connection on their machine. Falling squarely into the network-monitoring category, the program re-imagines the classic command-line netstat tool as a modern graphical interface that refreshes automatically, eliminating the need to re-run commands or parse scrolling text. Each socket is displayed alongside its protocol, local and remote addresses, state, and the owning process name, making it immediately obvious which application is responsible for outbound or inbound traffic. An integrated filtering bar lets analysts narrow the list by port, IP, PID, or process name, so troubleshooting a specific service or hunting for suspicious endpoints becomes a matter of typing a few characters. Security researchers use Netstat Cat to spot unexpected listeners after software installation, gamers check for background updaters that might add latency, and system administrators validate firewall rules by watching ports toggle between listening and established states in real time. Because the single published version 0.1.0 keeps resource usage minimal, it can stay open on secondary monitors without affecting system performance. The tool requires no elevated rights for basic inspection, yet still highlights services running under SYSTEM or other accounts when permissions allow, giving a complete picture of network activity at a glance. Netstat Cat is available for free on get.nero.com, where downloads are supplied through trusted Windows package sources such as winget, always serving the latest build and supporting batch installation alongside other applications.
