SDK

An SDK (software development kit) is a package of libraries, APIs, and tools that lets developers integrate a service into their app. In mobile analytics and monitoring, the SDK captures events, crashes, performance, and replays on-device and transports them to a backend. Consolidating capabilities behind one SDK reduces app weight, duplicated user identity, and inconsistent event schemas.
