The following is a list of the feature flags available in Rancher:

- `dashboard`: This feature enables the new experimental UI that has a new look and feel. The dashboard also leverages a new API in Rancher which allows the UI to access the default Kubernetes resources without any intervention from Rancher.

- `istio-virtual-service-ui`: This feature enables a [UI to create, read, update, and delete Istio virtual services and destination rules](../getting-started/installation-and-upgrade/advanced-options/enable-experimental-features/istio-traffic-management-features.md), which are traffic management features of Istio.

|
||||
- `proxy`: This feature enables Rancher to use a new simplified code base for the proxy, which can help enhance performance and security. The proxy feature is known to have issues with Helm deployments, which prevents any catalog applications to be deployed which includes Rancher's tools like monitoring, logging, Istio, etc.
|
||||
- `unsupported-storage-drivers`: This feature [allows unsupported storage drivers.](../getting-started/installation-and-upgrade/advanced-options/enable-experimental-features/unsupported-storage-drivers.md) In other words, it enables types for storage providers and provisioners that are not enabled by default.
