| Requirements | Docker is required to use k3d, and kubectl is used to interact with the Kubernetes cluster. | The documented macOS requirements include macOS 13 or higher, a persistent internet connection, and an Apple Silicon or Intel processor with VT-x. |
| Support | The overview directs users to the Rancher community Slack and its #k3d channel for discussion. | Community support is available through the Rancher Desktop Slack channel and GitHub Issues. |

In their own words
k3d
k3d is a free, community-driven wrapper that runs k3s, Rancher Lab’s minimal Kubernetes distribution, inside Docker. It creates single-node and multi-node clusters for local Kubernetes development and can support hot-reloading, Tilt build-deploy-test workflows, and Drone CI service use. Docker is required, while kubectl is used to interact with clusters. For k3d v5.x.x, the overview specifies Docker v20.10.5 or later and runc v1.0.0-rc93 or later. A registries.yaml file configures registries, authentication, and certificates, and documentation covers local registries managed by k3d. Services can be exposed through Ingress or NodePort by mapping container ports to the host. Covered k3s integrations include CoreDNS, local-path-provisioner, Traefik, and the Klipper service load balancer. Installation options include release binaries, Homebrew, AUR, Chocolatey, Scoop, arkade, asdf, and Go. k3d runs on Linux, macOS, Windows, and self-hosted setups. It is not an official Rancher (SUSE) product.
Rancher Desktop
Rancher Desktop is a free, open-source desktop application for managing local containers and Kubernetes on macOS, Windows, and Linux. Users choose Moby/dockerd with the Docker CLI or containerd with nerdctl to build, push, pull, and run containers. Its built-in Kubernetes uses k3s, and Preferences let users select a Kubernetes version or reset Kubernetes and the container runtime. The graphical interface manages images, containers, settings, and local Kubernetes resources, with controls for networking, virtual-machine resources, and registry access. Installation includes Helm, kubectl, nerdctl, Moby, and Docker Compose. Trivy-based image scanning reports vulnerabilities and configuration issues, and Docker Desktop Extensions can be installed through the UI catalog or rdctl. The application uses a virtual machine on macOS and Linux and WSL 2 on Windows. Windows requires WSL and virtualization capabilities; without the privileged service, exposed container applications are limited to 127.0.0.1. The project is intended for local container and Kubernetes work, rather than managing Kubernetes clusters.
