# Kubecost Open Source UI The preferred install path for Kubecost is via Helm chart, and is explained [here](http://docs.kubecost.com/install) To manually run an open source demo UI, follow the steps below. ## Requirements * `nodejs >= 12.0.0` * `npm >= 7.0.0` ## Installation & Running To run the UI, open a terminal to the `cost-model/ui/` directory (where this README is located) and run ``` npm install ``` This will install required depndencies and build tools. To launch the UI, run ``` npx parcel src/index.html ``` This will launch a development server, serving the UI at `http://localhost:1234` and targeting the data for an instance of Kubecost running at `http://localhost:9090`. To access an arbitrary Kubecost install, you can use ``` kubectl port-forward deployment/kubecost-cost-analyzer 9090 ``` for your choice of namespace and cloud context.
