webernetes

Webernetes runs a Kubernetes cluster entirely in your browser, no backend, no real infrastructure. You boot a cluster and create Pods, Services, Deployments, and Namespaces, define container images in TypeScript, and watch HTTP and DNS traffic move between them. Built by ngrok for teaching and demos, Apache-2.0, free, and published as an npm package with a live demo.

Because it is a simulator, setup is trivial and there is nothing to provision. It models a useful subset of Kubernetes resources so the behavior feels real enough to learn from, without the cost or wait of a live cluster. The trade is obvious: it is not real Kubernetes and will not run production workloads, by design.

This is for educators, content authors, and developers learning Kubernetes who want hands-on cluster behavior without spinning up infrastructure. Solo or team, it is free. If you need a real cluster, or features beyond the supported core resources, reach for the real thing: kind, k3s, or minikube for local work, a managed cluster for production.

The catch is the boundary of the simulation. Webernetes is a teaching tool, and a clever one, but the moment you need behavior it does not model, you are back to a real cluster. Use it to build intuition, not to validate production config.
