K3s vs Kube Inspector

K3s is a certified, lightweight Kubernetes distribution for IoT and edge computing. It runs self-hosted on Linux and is released for x86_64, ARMv7, and ARM64. The distribution arrives as one binary or a minimal container image; the site describes the binary as under 70 MB, while documentation says under 100 MB. Documented uses include edge systems, homelabs, IoT, continuous integration, development, ARM single-board computers, air-gapped environments, and embedded Kubernetes. SQLite is the default datastore, with etcd, MySQL, and Postgres available. K3s packages containerd or cri-dockerd, Flannel, CoreDNS, Traefik, ServiceLB, Kube-router, local-path-provisioner, and Spegel. High-availability deployments can use embedded storage or external MySQL, PostgreSQL, or etcd. Air-gapped installation supports private registries, manually deployed images, or an embedded registry mirror. Security guidance includes hardening and CIS self-assessment material. Automated Kubernetes-native upgrades use Rancher’s system-upgrade-controller.

Kube Inspector is a free visual desktop client for viewing and managing Kubernetes clusters on Windows, macOS, and Linux. It handles Pods, Deployments, StatefulSets, Jobs, and CronJobs, and includes a Monaco YAML editor with schema validation for applying changes. The interface shows CPU and memory readings over time for clusters, nodes, pods, and workloads when metrics-server is installed. Security tools include an interactive RBAC graph and Trivy image vulnerability scanning. Existing kubeconfig files work with conformant local and managed clusters, including kind, minikube, k3s, EKS, GKE, and AKS. Multiple clusters can be opened while panels remain pinned to their original cluster. A separate kube-inspector-cli offers the same features for terminal and SSH use. The project states that it sends no telemetry, analytics, crash reports, or usage statistics. An optional AI assistant uses a configured Ollama host. The release is beta, and no support desk is provided.
