PortKiller is a cross-platform desktop application for monitoring and managing listening TCP ports on macOS and Windows. It provides one-click process termination, Kubernetes port-forward session management, and Cloudflare Tunnel visibility via a native menu bar or system tray UI.
Use cases
- find which process is using port 3000 and kill it
- monitor listening ports from the macOS menu bar
- manage kubectl port-forward sessions with auto-reconnect
- view active Cloudflare Tunnel connections
- get notified when a watched port starts or stops listening
- search and filter ports by process name
When to choose
- you need a GUI alternative to lsof/netstat for killing port-hogging processes
- you frequently manage Kubernetes port forwards and want auto-reconnect and notifications
- you want a native menu bar/tray app on macOS or Windows
When to avoid
- you need headless or CLI-only port management in scripts or CI
- you need Linux support
- you need deep network packet inspection rather than port/process management
