PortKiller is a cross-platform port management tool for developers that makes it easy to monitor network ports, manage Kubernetes port forward sessions, integrate Cloudflare Tunnels, and kill processes using a friendly UI. It auto-discovers all listening TCP ports on your machine, lets you filter and search through them, and provides one-click graceful or forceful termination of processes holding those ports. Beyond basic port listing, PortKiller includes Kubernetes port-forward session management with auto-reconnect and connection logs, plus Cloudflare Tunnel visibility so you can keep track of external tunnels. Designed with native UI for macOS and Windows, it integrates with the system menu bar or tray for quick access, notifications, watched ports, and favorite lists for frequently monitored items. Its cross-platform support and refined UX help developers troubleshoot network issues, free up ports, and streamline local networking tasks without switching to the command line.
