port-killer

Port-Killer is a native macOS menu bar application designed to help developers manage open ports by locating and terminating processes. It integrates seamlessly into the menu bar, avoiding unnecessary clutter in the Dock. The app automatically discovers all listening TCP ports and provides detailed process information, including process names and PIDs. With features like one-click process termination, a "Kill All" option, and an auto-refreshing port list every five seconds, Port-Killer offers efficient port management. Users can search by port number or process name and benefit from a graceful kill approach, attempting SIGTERM before resorting to SIGKILL. Compatible with macOS 15.0 and above, Port-Killer can be installed via Homebrew or by downloading the latest DMG from GitHub Releases. It is developed primarily in Swift and is open-source under the MIT license.
