Kubernetes Load Balancer Port Checker

Use this tool to verify if a Kubernetes LoadBalancer or NodePort service is accessible from the internet. It's designed for engineers managing clusters on bare metal servers or public cloud.

When you expose a service using `type: LoadBalancer` or a NodePort, ensuring that it's reachable externally is critical for deployments, integrations, and performance monitoring. This tool checks whether a given IP address or domain and port combination is open, accessible, and serving responses.

This is especially useful when working with complex topologies using Kubernetes clusters, where you rely on traffic routing through cloud controllers or metalLB. Combine it with your load balancing service to ensure redundancy and availability.

Just enter the public IP or DNS of your Load Balancer or Node, specify the port, and hit check. The result will indicate if the service is reachable from this browser client.
