Deciding between an SDK
and an API
is critical in modern software development. SDK
and API
enable developers to add features and functionalities to their software faster. However, their capabilities and how they work on the backend differ.
What’s an SDK?
SDK
stands for "Software Development Kit
." It is a set of tools, including a library of API
s, that provides a software developer with the necessary components to build applications for a specific platform. SDK
s are for a particular platform or programming language.
Android and iOS SDK
s are platform-specific SDK
examples. .NET and Python SDK
s are programming language-specific SDK
examples.
SDK
s provide access to pre-built libraries and tools. Thus, enterprises save time and resources during development. SDK
s also ensure that an application works correctly on a specific platform, as an SDK
includes the necessary API
s and other components to access platform-specific features and functionality.

What’s an API?
API
stands for Application Programming Interface
. It is a set of rules and protocols that allow applications to communicate with each other. API
s transfer data or functionality among applications.
API
s provided by social media platforms allow developers to access data such as user profiles, posts, and images.
Unlike SDK
s, API
s follow a standard flow. An application using API
is called a client application. It sends an API
endpoint of a 3rd party service a request, which can be for functionality or information. The 3rd party service provider processes the request and communicates the result to the client application. Let’s take a transcription functionality request as an example. A client application sends a request with voice data, and a 3rd party service converts voice data to text on its platform, and then sends the text to the client application.
Picovoice supports all modern frameworks and offers intuitive SDK
s that run everywhere. It takes only a few lines of code and minutes to get started.
