## What it is
Apollo Kotlin is a strongly-typed, caching GraphQL client for JVM, Android, and Kotlin Multiplatform targets. It provides code generation from GraphQL operations, normalized in-memory or SQLite caching, subscriptions, and developer tooling.

## Use cases
- consume a GraphQL API from an Android app
- build a Kotlin Multiplatform app with a shared GraphQL client
- cache GraphQL query results locally with a normalized cache
- generate type-safe Kotlin models from GraphQL operations
- handle GraphQL subscriptions over websockets in Kotlin
- use persisted queries with a GraphQL server
- migrate an Android app from Apollo Android to Apollo Kotlin

## When to choose
- you need a production-tested, type-safe GraphQL client on Android or JVM
- you want one GraphQL client shared across Kotlin Multiplatform targets
- you need normalized caching, pagination, or @defer support out of the box
- you use Apollo GraphOS features like persisted queries

## When to avoid
- your backend is REST, not GraphQL
- you need a GraphQL client for Swift/iOS or JavaScript/web - use Apollo iOS or Apollo Client instead
- you only need a lightweight hand-rolled HTTP call without code generation or caching
- your project does not use Kotlin or Java
