Software Development Kit - Definition

software development kit definition

Software development kit explained simply: A software development kit (SDK), also known as a software development management tool or software development planning tool, is a collection of tools, libraries and documentation that helps developers to create software applications for specific platforms, operating systems or frameworks. Among other things, an SDK has a range of programming interfaces (APIs) that developers can use to access certain functions or services and integrate them into their apps.

In addition, an SDK often includes compilers, debuggers, and other tools to help develop and test software. It also provides examples, tutorials, and guides to help developers get started with the development environment.

By using an SDK, developers can save time and effort by accessing code and pre-built functionality that has already been created - instead of developing everything from scratch.

SDKs are widely used in various fields, including mobile applications, web development, game development, and IoT (Internet of Things). They are created by enterprises, platform providers, and programmers to promote and support the development of applications on their platforms.

Software Development Kit vs. API

A software development kit and an Application Programming Interface (API) are both tools used in software development. However, they have different functions.

An SDK is a collection of tools, libraries, and documentation that help developers create software applications. It often includes pre-built functions, modules, and examples that facilitate development. An SDK provides programmers with a more comprehensive environment in which to create applications.

An API is an interface that allows applications to communicate with other software components. It defines the methods and protocols that can be used by an application to interact with a particular software or service.

In short, an SDK is a comprehensive application development toolkit, while an API is simply an interface that provides access to specific functions or services.
