Fuel is a Kotlin-first HTTP networking library built on Kotlinx Coroutines, offering a fluent API for GET/POST/PUT/DELETE/HEAD/PATCH requests on JVM and Android, with multiplatform support for Apple platforms. It provides optional modules for deserialization (Gson, Jackson, Moshi, Kotlinx Serialization), coroutines, RxJava, LiveData, and Reactor integration.

Use cases

• make HTTP requests from Kotlin with a fluent API
• call REST APIs from an Android app
• download files over HTTP in Kotlin
• upload multipart form data with files and blobs
• deserialize JSON responses into Kotlin data classes
• use coroutines for async networking in Kotlin

When to choose

• you want a simple, idiomatic Kotlin HTTP client for Android or JVM
• you need coroutine-based async requests with optional RxJava/LiveData/Reactor adapters
• you want built-in deserialization modules and easy file upload/download

When to avoid

• you need a fully stable 3.x release (currently alpha)
• you prefer Ktor client or Retrofit for more mature ecosystems
• you target Android below API 21 or Java below 8
