PortKiller 3.2.0

PortKiller is not just a tool for closing ports — it's a cross-platform solution for monitoring and managing ports with powerful functionality. It listens to all TCP ports, identifies active processes, and displays detailed information about each process. Specifically designed for software developers and network administrators, PortKiller goes beyond simple port monitoring and process termination: it lets you filter by process type, simplify process management, handle Kubernetes port forwarding, manage Cloudflare Tunnels, and even share active connections.

PortKiller can also manage and share port connections through a dedicated Cloudflare Tunnels section. Here, you can view tunnel details, check connection uptime, and open them directly in your browser. To use this feature, Cloudflare must be installed on your system.

Additionally, PortKiller supports creating kubectl port forwarding sessions, allowing local machines to connect to resources running in a Kubernetes cluster. Released as open-source software, PortKiller is a valuable asset for developers and IT professionals seeking advanced yet user-friendly network management capabilities.
