PortPeek is a lightweight Windows tray application developed by Hisham Medhat that gives users a clear, immediate view of which processes are listening on local network ports, along with the ability to free an occupied port with a single click. Designed for quick diagnostics rather than deep system administration, the tool continuously or on demand enumerates every process bound to a local port and presents that information in an accessible tray-based interface, so users can identify conflicts without opening command-line utilities or digging through system tools. Its core purpose is troubleshooting port contention: developers running local web servers, databases, or development stacks frequently encounter "port already in use" errors, and PortPeek lets them see exactly which application or process is responsible and terminate or release it directly from the same window. Typical use cases include web and software developers freeing ports like 3000, 8000, or 5432 when a service fails to start, testers resetting local environments between runs, and power users investigating unexpected listeners on their machines as a basic security and hygiene check. The software falls into the network utilities and system diagnostics category, with a particular focus on local port monitoring and process management, and its tray-resident design means it stays out of the way until needed while remaining one click away. The current version is 1.2.3, and the catalog records three released versions in total, indicating an actively maintained project with a short but established release history. PortPeek targets Windows specifically, keeping its footprint small and its interface focused on the two actions users need most: seeing what is listening and clearing a busy port. By consolidating these tasks into a single small utility, it removes the need to memorize commands such as netstat or taskkill, making routine port management faster and more approachable for everyday development workflows.
