# Aura Interfaces

:::note
Use Lightning Web Components (LWC) where possible for new development. For more information, see [Migrate Interfaces](https://developer.salesforce.com/docs/platform/lwc/guide/migrate-interfaces.md).
:::

Aura Interfaces make your components available for use on record pages, flow screens, utility bars, and Aura-based Experience Builder sites. These interfaces enable you to integrate custom component logic with platform capabilities, allowing components to participate in declarative configuration and extend legacy Salesforce functionality.

## Marker Interfaces

Marker interfaces enable a component to be used in a specific page or app, such as in Lightning App Builder, Experience Builder, and more.

## Functional Interfaces

Functional interfaces provide additional functionality to a component, such as enabling the component to be addressable directly via a URL.

- [Allow In Relaxed CSP](/docs/platform/lightning-component-reference/guide/lightningcommunity-allow-in-relaxed-csp.md)

- [Has Item Context](/docs/platform/lightning-component-reference/guide/clients-has-item-context.md)

## Template Interfaces

Template interfaces enable a component to be used as custom Lightning page templates in Lightning App Builder or Experience Builder. Each component can implement only one template interface and cannot implement other interfaces.

- [App Home Template](/docs/platform/lightning-component-reference/guide/aura-app-home-template.md)
