Retrofit is a type-safe HTTP client for Android and the JVM that turns REST APIs into Java or Kotlin interfaces using annotations. It generates implementations of these interfaces and supports synchronous and asynchronous requests, converters, and multipart uploads.

Use cases

• consume a REST API from an Android app
• turn an HTTP API into a typed Java interface
• make type-safe network requests on the JVM
• upload files via multipart requests
• deserialize JSON API responses into Java objects
• call remote web services with declarative annotations

When to choose

• you are building an Android or JVM app that talks to a REST API
• you want declarative, annotation-based HTTP clients instead of manual request code
• you need mature, widely adopted networking tooling with converter and adapter ecosystems

When to avoid

• you need a non-HTTP protocol like raw TCP or WebSockets
• you are not on the JVM or Android platform
• you want a fully dynamic HTTP client without interface definitions
