The record

Purpose: K9s is a terminal UI for navigating, observing, and managing Kubernetes clusters and their applications.
Live monitoring: It watches Kubernetes for changes and tracks resource activity in real time.
Resource support: It handles standard Kubernetes resources and custom resource definitions (CRDs).
Metrics: It tracks real-time metrics for resources including pods, containers, and nodes.
Management actions: Its cluster management commands include viewing logs, scaling, port forwarding, and restarting resources.
Extensions: Users can add cluster commands through plugins, which run configured commands with resource and cluster context variables.
RBAC: K9s can display RBAC rules and look up what a user, group, or ServiceAccount can do on a cluster.
Benchmarking: K9s integrates Hey to benchmark HTTP endpoints through port forwards and services; port forwards end when the K9s session exits.
Views and customization: Pulses summarizes cluster state, XRay shows resource dependencies, and users can customize skins, columns, aliases, and hotkeys.
Platforms: The installation page lists Linux, macOS, and Windows, with platform-specific package-manager options and release binaries.
Security controls: K9s supports read-only mode, which disables resource modification commands.
Security and compliance: The opened maker pages identify the Apache License 2.0 but do not state security certifications or compliance attestations.
Support and audience: The project invites sponsorship and community contact through its K9ers Slack, and describes K9s as a tool for Kubernetes cluster users.
Compatibility limit: The repository says K9s works best with later Kubernetes versions and warns that older versions or insufficient RBAC permissions can cause problems.
