K9s vs kind

K9s is a free, open-source terminal interface for navigating, observing, and managing Kubernetes clusters and applications. It watches cluster changes, tracks resource activity in real time, and shows metrics for pods, containers, and nodes. Standard Kubernetes resources and custom resource definitions are supported. Users can view logs, scale resources, restart them, and create port forwards. Pulses summarizes cluster state, while XRay shows resource dependencies. Skins, columns, aliases, and hotkeys are customizable, and plugins add cluster commands with resource and cluster context variables. K9s displays RBAC rules and can show what a user, group, or ServiceAccount may do. Read-only mode disables resource modification commands. Integration with Hey supports HTTP endpoint benchmarking through port forwards and services; those forwards end when the K9s session exits. K9s runs on Linux, macOS, and Windows, has no graphical interface, and is licensed under Apache License 2.0. The project prefers Kubernetes 1.28 or later and warns that older versions or insufficient RBAC permissions can cause problems.

kind runs local Kubernetes clusters with Docker container nodes, mainly for Kubernetes testing; local development and CI are also listed uses. It bootstraps cluster nodes with kubeadm and supports multi-node setups, including high availability. A configuration file can define worker and control-plane nodes, port mappings, and Kubernetes versions.

The tool can build Kubernetes release builds from source or use pre-published builds. It can detect Docker, Podman, or nerdctl as its container provider, including rootless providers subject to host and provider requirements. Users can load Docker images or an image archive into a cluster. Documentation covers ingress and Gateway API configuration with cloud-provider-kind, private registry workflows, and Kubernetes API audit logging.
