Port Manager Extension

Find processes that are listening on TCP ports, name frequently used ports, and terminate the associated process directly from Raycast.

Commands

• Open Ports lists TCP listeners, their ports, process details, and available actions.
• Kill Process Listening on terminates every process listening on a port you provide. Results and errors are shown in a toast.
• Named Ports lets you assign memorable labels to ports in the list.
• Open Ports in Menu Bar provides the open-port list from the macOS menu bar.

On macOS, the Kill Signal preference controls whether to ask for SIGTERM or SIGKILL, or always use one. Windows does not support Unix signals, so every kill uses taskkill /F.

A kill is only reported as successful once the process has actually exited. A process that ignores the signal is reported as still running, with a one-key Force Kill to follow up with SIGKILL.

Some system-owned processes and executable paths are protected by the operating system. The extension will show the command error in Raycast when the current user lacks permission; use an elevated terminal only when you understand the process you are stopping.
