# Software development kit (SDK)

## What it is and how it works

It usually includes compilers or debuggers, code libraries, emulators and guides. For example, the Android SDK is used to build apps for that system, and payment, mapping or analytics services provide SDKs so they can be integrated into an app without coding everything from scratch.

It differs from an API in that the API is the interface that defines how to communicate with a service, while the SDK is the toolkit that makes it easier to use. Adding a third-party SDK to an app brings features but also extra size, dependencies and possible privacy implications that should be reviewed.
