PortKiller

A powerful cross-platform port management tool for developers. Monitor ports, manage Kubernetes port forwards, integrate Cloudflare Tunnels, and kill processes with one click.

PortKiller is a cross platform desktop port management tool for developers that discovers listening TCP ports and shows which processes are bound to them. It lets you search and filter by port or process name, pin favorites, watch specific ports with notifications, and terminate processes with a single action using either a graceful stop or a force kill.

Beyond local ports, PortKiller can create and manage kubectl port forward sessions with status, logs, auto reconnect, and connect or disconnect notifications. It also provides visibility into active Cloudflare Tunnel connections, plus native integration on each platform, including a macOS menu bar app and a Windows system tray app.
