Eppo: sovereignty score and 8 European alternatives

Eppo is an experimentation platform that now operates as Datadog Experiments. It combines A/B testing with feature flagging, covering feature gates, controlled rollouts, kill switches and dynamic configuration. Its statistics engine supports sequential, fixed-sample and Bayesian methods, and the platform also offers contextual bandits and the testing of AI models against business metrics. The architecture is warehouse-native: analysis runs on data that stays in the customer's own data warehouse, with integrations for Snowflake, BigQuery, Redshift, Databricks and dbt.

Datadog acquired Eppo in May 2025. Datadog is a US company headquartered in New York City, so the product falls under US jurisdiction, including the CLOUD Act. Eppo is proprietary software and no self-hosted edition is described. Because the experiment analysis runs in your own warehouse, the location of that warehouse largely determines where analytical data resides. The website does not say where the vendor's own control layer is hosted. European organisations looking for a non-US provider should treat this as a US-controlled service.

Why digital sovereignty matters with Eppo

Eppo is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Eppo hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Eppo is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Eppo together with your other vendors and gives a total score, a heatmap and the main risk drivers.
