The "Multi-Site / Multi-Login" feature in the Ory Network's price list refers to the ability to have multiple custom domains registered for a single Ory Network project. This feature is available starting with the Scale plan. Each custom domain can have a different custom UI base URL, allowing each domain to serve its own set of UI views. This provides a high degree of flexibility, especially for businesses that have different online storefronts or services, each with its own domain and user interface. For example, a company with three different online storefronts can use this feature to allow customers to use one account across all storefronts, while each storefront serves its own unique UI views. This setup can be created using the User Interface view in the Ory Console. Here's an example of how this might look: | Site | Domain | Base URL | | --- | --- | --- | | mufflers.com | acme-auto-mufflers.store.prod |

<http://mufflers.com/auth|mufflers.com/auth>

| | carseats.com | acme-carseats.store.prod |

<http://carseats.com|carseats.com>

| | wipers.com | acme-wipers.store.prod |

<http://wipers.com/self-service/|wipers.com/self-service/>

| In this example, users who create an account in one of these stores can use it to shop in the other stores as well. The UI changes depending on the store the user visits, allowing for consistency with the established visual identity of each of the company's brands. For more details, you can refer to the [Ory documentation on multiple custom domains setup](https://www.ory.sh/docs/kratos/bring-your-own-ui/configure-ory-to-use-your-ui#multiple-custom-domains-setup).
