> **TL;DR**
> Product Help: [Facets](https://www.jetbrains.com/help/idea/facet-page.html), [Adding frameworks (facet)](https://www.jetbrains.com/help/idea/adding-support-for-frameworks-and-technologies.html)

A facet represents configuration specific for a particular framework/technology, associated with a module. A module can have multiple facets. For example, Spring Framework-specific configuration is stored in a dedicated [Spring facet](https://www.jetbrains.com/help/idea/spring-projects.html).

## Working with Facets

> **Note: Workspace Model API (2024.2+)**
> The [Workspace Model](workspace-model.html) API is available since 2024.2 for use by third-party plugins and should be preferred over using the [Project Model](project-model.html) API.

### Managing Facets

To create, search, and access the list of facets for a module, use [FacetManager](https://github.com/JetBrains/intellij-community/tree/idea/263.7307.200/platform/lang-core/src/com/intellij/facet/FacetManager.java).

### Facet-Based Tool Window

A [tool window](tool-windows.html) dependent on the existence of given facet(s) can be registered via [com.intellij.facet.toolWindow](https://jb.gg/ipe?extensions=com.intellij.facet.toolWindow) extension point .
