Port-killer is a TCP port management utility and process termination tool. It provides a system for discovering listening TCP ports and terminating the processes occupying them to free up network resources.
The project includes a port forwarding manager and a network tunnel monitor to track active connections and verify their operational status. These components support the management of Cloudflare tunnels and Kubernetes port forwarding, incorporating automatic reconnection and status logging to maintain stable connectivity.
The utility covers broad network management capabilities, including network port monitoring with search and filter tools for organizing active sockets. It handles process termination by mapping active listeners to operating system process IDs and employing a signal escalation strategy to release blocked ports.
