k3d vs Kunobi

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.

Kunobi is a Kubernetes management platform for visibility and control of deployments across clusters and GitOps sources. It runs locally on macOS, Windows and Linux, connecting directly to clusters over the user's network. Kunobi says kubeconfig and cluster credentials stay on the user's device and that it does not proxy or store cluster traffic. Its interface brings Git and cluster resources together, with native Flux and Argo CD support and views for Helm releases and configuration changes. It advertises dedicated views for more than 105 resources, including Kubernetes core, Flux, Argo CD, cert-manager and Prometheus. The Free plan supports up to three clusters and can connect external AI tools through an MCP server. Pro lists unlimited clusters, integrations with EKS, GKE and AKS, cross-cluster log tailing, PromQL queries, metrics exploration and AI cluster actions with an approval firewall. Enterprise includes SAML SSO, SCIM provisioning, live onboarding, unified billing and usage analytics. Free costs nothing; Pro is listed at $912 a month with limited-time launch pricing, while paid pricing is also listed from $12/mo.
