Cluster API vs KubeStellar

Cluster API is an open-source project for managing the lifecycle of multiple Kubernetes clusters through declarative APIs and tooling. Platform operators can use it to create, scale, upgrade, and destroy Kubernetes-conformant clusters across on-premises and cloud environments. Provider implementations are interchangeable; kubeadm is the default bootstrap provider. The ecosystem includes infrastructure, bootstrap, control plane, IPAM, addon, and runtime extensions, with environments such as AWS, Azure, GCP, OpenStack, vSphere, and KubeVirt. A management cluster can use clusterctl or the Cluster API Operator to manage provider components. Clusterctl fetches provider component YAML and installs it, while the Operator uses a declarative approach intended to support GitOps workflows. Getting started requires an existing Kubernetes cluster accessible through kubectl; kind, Docker, and Helm are common prerequisites. Cluster API supports multi-cluster provisioning and upgrades, but does not manage a single cluster spanning multiple infrastructure providers or clusters it did not provision. It is free and open source. The project supports its latest two minor releases, with each supported for roughly 12 months including maintenance.

KubeStellar Console is a free dashboard for managing workloads and operations across Kubernetes clusters. It shows real-time cluster health, cross-cluster resources, workloads, and mission progress, with cluster groups and customizable layouts. Clusters can be discovered through a user’s kubeconfig; examples include OpenShift, EKS, GKE, kind, and k3s. AI Missions accept natural-language requests to investigate issues, troubleshoot, repair, upgrade, or deploy across clusters. Users can approve or reject suggested actions. The Console also supports cluster provisioning and policy enforcement, and its security dashboard includes CIS, NSA, and PCI compliance scoring, RBAC analysis, and privileged-container detection. Documentation lists 20+ dashboards, 110+ card types, and 93+ stats blocks; custom cards can be built with AI, JSON definitions, or TSX code. The marketplace offers community dashboards, card presets, and themes. Licensed under Apache 2.0, it runs on Linux and macOS and can be self-hosted or used on the web. AI Missions require an optional Anthropic API key.
