| GitOps | The Cluster API Operator uses a declarative approach to manage providers and aims to support day-to-day workflows with GitOps. | Deployments can use Git repositories, automatic GitOps updates, webhooks, stored shared credentials, deployment gates and code-only deployment enforcement. |
| Integrations | The quick start lists infrastructure providers including AWS, Azure, GCP, OpenStack, vSphere, and KubeVirt, among others. | The product pages identify Talos Omni integration for provisioning Kubernetes clusters and support deployment from Helm charts. |
| Purpose | Cluster API provides declarative APIs and tooling to provision, upgrade, and operate multiple Kubernetes clusters. | Portainer is a centralized multi-cluster management platform for managing Kubernetes clusters and container environments. |

In their own words
Cluster API
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.
