Show HN: Rejourney – Open-source revenue leak prediction for web and mobile apps

Rejourney is a lightweight, open-source observability tool designed to detect revenue leaks in web and mobile applications. By monitoring critical business transitions like checkout, activation, and subscription renewals, it compares current cohorts against healthy baselines to identify potential failures before they impact the bottom line. Supporting platforms like Next.js, React Native, and Swift, Rejourney combines session replay with journey maps, heatmaps, and API performance data to provide a complete investigative surface. This self-hostable solution helps teams pinpoint the exact user experience or technical error causing lost revenue, enabling faster fixes and improved product stability.

"Revenue is an outcome, not a useful unit of diagnosis. Rejourney protects explicit business states such as signup, checkout, and renewal by using leading signals to rank risk before a lagging aggregate makes it obvious."
