# Manage Helm Apps

The Devtron Dashboard displays the helm applications deployed to your cluster and lets you deploy your own helm charts or third-party charts (e.g. postgresql) using the [Chart Store](https://docs.dashboard.devtron.ai/user-guide/chart-store).

## View Helm Apps

1. From the left pane, go to **Applications**.
2. Click the **Helm Apps** tab.

You can see the Helm Apps available in your cluster. If you have connected more than one cluster to Devtron, you can use the **Cluster** selection dropdown to view the respective Helm Apps in your other clusters.
