Many developers contemplate creating software development kits (SDKs) due to the fascination with writing code for code. However, in modern programming, there's a strong reliance on shared, reusable code from third parties, which enables the creation of powerful and useful software. Instabug's SDK is not just an afterthought; it's a collection of code libraries that work together to create a robust framework for bug reporting, crash reporting, and app performance monitoring. The development process was challenging, requiring overcoming a steep learning curve and addressing scalability, third-party code, testing, user impact, main thread freedom, device equality, security, customization, changing landscapes, and simplification of integration, setup, and customization. Instabug's SDK has matured over the years, and the company is now sharing its learned experiences to help others navigate similar challenges.
