SDK

A Software Development Kit (SDK) is a collection of tools, libraries, documentation, and code samples provided by hardware or software vendors to help developers build applications for specific platforms or frameworks. SDKs simplify development by providing pre-built functions and standardized resources, allowing developers to focus on building features instead of coding everything from scratch.
SDKs can include APIs, debuggers, compilers, emulators, and testing environments. They are essential for creating applications that integrate smoothly with operating systems, hardware devices, or third-party services such as payment gateways, analytics, or cloud platforms.
Advanced
SDKs often bundle application programming interfaces (APIs) with development environments that accelerate integration. They can also enforce best practices by defining how developers should interact with systems or services. For example, a mobile SDK may include UI components, security modules, and sample projects for iOS or Android.
Advanced SDKs are frequently updated to support new features, security improvements, and platform changes. They may provide cloud-based services, telemetry, or analytics to monitor app performance. Some SDKs are proprietary, tied to vendor ecosystems, while others are open source to encourage community adoption and customization.

Example
A fintech startup used a payment gateway SDK to integrate secure transactions into its mobile app. Instead of building encryption and compliance systems from scratch, the SDK provided ready-to-use components, reducing development time and ensuring compliance with industry standards.
