React Native Detour is an SDK for handling deferred deep links in React Native applications. It helps apps understand where users should land after installation, even when the original link was opened before the app existed on the device. This is useful for onboarding flows, referral campaigns, shared content links, invite systems, and marketing attribution. The SDK is designed to connect React Native apps with Detour credentials and platform-level integration. It gives developers runnable examples so they can test linking behavior in realistic app scenarios. Its main value is reducing friction around deferred linking, so users can move from a link to the correct in-app destination more reliably.
