About the SDK Market and Choosing the Best SDK for Mobile Apps

Software Development Kits (SDKs) are integral to the mobile app economy, enabling developers to add new features and functionalities to their apps, games, and services, without having to build them from scratch. They facilitate everything from app monetization to data collection and analytics, security and privacy, and audio and visual enhancements.

Moreover, demand for increasingly niche features has led to a highly competitive SDK market, with SDK providers competing both to build more specialized solutions and to carve out more granular segments of the market. They’ve sliced and diced the industry based on app genre, user demographic, language availability, regional and country availability, and more.

To put a finer point on it, finding the best SDK for your mobile app is relative! You need to consider things like where your user base is located, what aspects of your app you need to develop in-house, what solutions your competitors are using, etc.


Our Data: How We Identified the Best SDKs

To help you navigate the ins and outs of the SDK market, we put together the following list. It was compiled using the 42matters SDK Explorer, a web-based research and lead generation tool for mobile app and SDK developers. All SDKs were chosen based on popularity, as determined by the number of installations across iOS and Android apps. In addition, we limited our results to SDKs that are available to both platforms, meaning Google- and Apple-branded SDKs are generally omitted.

That said, if you’d like to see the best performing iOS- and Android-specific SDKs, don’t hesitate to reach out!
