## What it is
The official JetBrains plugin that adds Scala language support to IntelliJ IDEA and Android Studio. It provides coding assistance, navigation, refactoring, build tool integration (sbt, Maven, Gradle, BSP), testing framework support, and a Scala debugger.

## Use cases
- write Scala code in IntelliJ IDEA with completion and highlighting
- refactor Scala projects safely
- run ScalaTest or MUnit tests from the IDE
- debug Scala applications
- import and work with sbt, Gradle, Maven, or BSP projects
- use Scala worksheets and Ammonite scripts
- get support for Scala 3 features like named tuples and opaque types

## When to choose
- you develop in Scala and use IntelliJ IDEA or Android Studio
- you need IDE support for the latest Scala 3 syntax
- you want integrated sbt/BSP project import and test running

## When to avoid
- you use VS Code or another editor (consider Metals instead)
- you need HOCON support (moved to a separate plugin)
- you don't work with Scala or the JVM

## Facets
- artifact type: plugin
- maturity: active
- function: editor, developer-tools, testing
- domain: programming-languages, developer-tools, text-editors
