Eppo

Eppo (now Datadog Experiments) is an end-to-end experimentation and feature flagging platform designed for modern product teams running statistically sound A/B tests, managing feature rollouts, and connecting experiment results directly to business metrics. Eppo's core purpose powers feature experimentation and progressive delivery with fast and resilient feature flags for A/B tests, feature gates, controlled rollouts, kill switches, and dynamic no-code configuration. Experiment assignments use SQL snippets pulling from data warehouses, integrating with existing tools like LaunchDarkly. Eppo's SDKs serve experiment configs via CDNs with latencies below 50ms with server-side applications and mobile devices polling CDNs every few minutes for nearly instantaneous feature delivery. The platform enables warehouse-native experimentation with data scientist-friendly statistical implementations.
