AppsFlyer Review
The most widely deployed mobile measurement platform, with mature server-to-server integrations for privacy-first attribution.
Overview
AppsFlyer is the market leader in mobile measurement, used by tens of thousands of apps to attribute installs, in-app events, and revenue to ad campaigns. In a server-side context, AppsFlyer is important because it operates almost entirely server-side: SDKs collect events and dispatch them via server-to-server postbacks to ad networks, publishers, and analytics destinations.
The platform handles SKAdNetwork, Apple's privacy-safe attribution framework, alongside traditional deterministic and probabilistic matching. This makes it a critical piece of any post-IDFA mobile stack, and the server-side nature keeps attribution flowing even as browsers and OS platforms tighten client-side tracking.
Beyond mobile, AppsFlyer's People-Based Attribution links web and app users, making it useful for cross-platform businesses that need unified server-side measurement.
