| ---------------------------- | ------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------ |
| **Data source**              | Looker semantic layer                                                    | Snowflake warehouse (raw tables)                                                           |
| **Preserves Looker model**   | Yes — governed metrics and Explores carry over                           | No — model must be rebuilt in Power BI                                                     |
| **Power BI Service (Cloud)** | Supported                                                                | Not supported                                                                              |
| **Power BI Desktop**         | Supported                                                                | Supported                                                                                  |
| **Best for**                 | Customers using Looker who want a single source of truth across BI tools | Customers not using Looker, or building Power BI reports independently of the Looker model |

{% hint style="success" %}
**Recommendation:** If you're using Looker as your primary BI tool, connect Power BI via the Looker Connector. This preserves the governed metrics and Explores you've already built in Looker, so definitions stay consistent across reporting surfaces.
{% endhint %}

### Connection guides

#### Power BI via the Looker Connector

Use this method to connect Power BI to your Looker semantic layer. Your existing Explores, governed metrics, and dimensions are available directly in Power BI — no rebuilding required.

#### Power BI via Direct Snowflake Connection

Use this method to connect Power BI Desktop directly to your Daasity warehouse using the Snowflake connector and keypair authentication. This path does not use the Looker semantic layer — you'll build your data model in Power BI from the warehouse tables.

* [Power BI via Direct Snowflake Connection](https://help.daasity.com/core-concepts/bi-tools/power-bi/connecting-power-bi-desktop-to-daasity)

{% hint style="warning" %}
Power BI Service (Cloud) is not supported via direct Snowflake connection. Use the Looker Connector path if you need Power BI Service support.
