history
Project history and usage
PortKiller is a cross-platform desktop tool for discovering listening TCP ports, identifying and terminating their processes, and managing development-oriented forwarding and tunnel workflows.
Project history
PortKiller developed as a cross-platform desktop port-management project. Its scope grew beyond listing listeners and terminating processes to include watched ports, favorites, Kubernetes port-forward lifecycle management, and visibility into Cloudflare Tunnel connections.
Adoption history
PortKiller is distributed for macOS through Homebrew and as a direct download, while the official project also supports Windows.
How it is used
Developers use PortKiller to search active listeners, terminate a process gracefully or forcibly, watch important ports, receive state-change notifications, and manage port forwards from a macOS menu-bar or Windows system-tray application.
Why package nerds care
PortKiller packages familiar Unix troubleshooting operations—finding listeners, identifying processes, and terminating them—into a desktop interface. Its management of kubectl port-forward sessions and Cloudflare Tunnels broadens it from a port inspector into a developer networking dashboard.
Timeline
- The project expanded from local port and process management into Kubernetes port-forward and Cloudflare Tunnel workflows.
Related projects
- kubectl supplies the Kubernetes port-forward functionality managed by PortKiller.
- cloudflared is the Cloudflare Tunnel client whose active connections PortKiller can display and manage.
