THENEWSTACK - Nextdoor built an App Release Anomaly Detection tool that stops client-side regressions before they have a severe impact on the application. Nextdoor employs a phased rollout strategy for its weekly mobile releases. Initial users are limited to a new version to ensure safe and scalable deployments. Nextdoor started using "difference-in-differences" analysis to identify app session decline 10 days earlier than week-over-week figures.
