A hosted control plane for Kubernetes operators

Your own Kubernetes API. No nodes to run.

Apply your CRDs, deploy your controller's image, and let it reconcile what lives outside Kubernetes: virtual machines, DNS records, databases, SaaS accounts.

Create a control plane
An API server of its own, on an endpoint of its own.ctrlplane create dev --wait
Apply your CRDs
The API types your operator defines, with kubectl or the ctrlplane CLI.ctrlplane apply -f crds/
Deploy your controller
Any image. It runs next to your API with a kubeconfig for it, plus logs and metrics.ctrlplane controllers

Everything around the operator, handled

You write the reconcile loop. ctrlplane runs the API it talks to, the process it runs in, and the path to the systems it manages.

Your controllersAny image, run next to it. Edit, restart or remove them from the console.
Your networkReached through a tunnel. No inbound ports.
Metrics, logs and eventsReconcile rates, pod resources and searchable logs for every controller.
