The lean-stack take

For a lean startup team it supports the Build-Measure-Learn loop. A team ships a change behind a flag, splits traffic, and reads the result against metrics from its data warehouse or Datadog Product Analytics.

Best for

Product and engineering teams that already use Datadog and want flags and A/B tests read against warehouse or product data.

Watch out for

No Experiments price was confirmed from search results, so ask how flags and experiments are billed and confirm your warehouse is supported.

About

About Datadog Experiments (formerly Eppo)

Datadog Experiments is an A/B testing and feature flag product made by Datadog, Inc. It builds on Eppo, a warehouse-native experimentation company that Datadog acquired in 2025. Datadog announced the product's launch in April 2026.

Written by lean-stack from Datadog Experiments (formerly Eppo)'s public pages. Vendors can replace it with their own description by claiming this profile.

Features

What Datadog Experiments (formerly Eppo) offers

01

Feature flags

Datadog Feature Flags turn a change on for chosen users or a share of traffic. This supports small batch releases and quick rollback.

02

Client and server SDKs

The docs cover client-side flags for platforms including iOS, tvOS and React Native, plus a server-side setup. Engineers pick the SDK that matches where the change runs.

03

Warehouse-native analysis

Setup guides cover Snowflake, BigQuery, Databricks and Amazon Redshift. Experiment results can be computed on data the team already stores there.

04

Exposure SQL

Teams can define who saw each variant with SQL against their own tables. This keeps the exposure record tied to the same data used for metrics.

05

Experiment metrics

The docs describe creating experiment metrics and planning an experiment before launch. Agreeing on metrics up front makes the hypothesis testable.

06

CUPED variance reduction

The statistics docs include CUPED, which uses pre-experiment data to reduce noise in results. Less noise can mean a test needs less traffic to reach a result.

07

Product Analytics experiments

Datadog Product Analytics has its own experimentation docs page. Teams that already track user behavior there can read tests in the same place.

Strengths and limitations

What stands out, and what to watch

Strengths

  • Flags, experiments and analysis in one Datadog account
  • Documented warehouse connections for Snowflake, BigQuery, Databricks and Redshift
  • CUPED variance reduction is documented
  • Client-side flag docs cover iOS, tvOS and React Native
  • Builds on Eppo's warehouse-native experimentation product

Limitations

  • No public Experiments pricing confirmed from search results
  • Renamed from Eppo in 2026, so older Eppo pages still appear in searches
  • Gets most value when the team already uses Datadog or a supported warehouse
  • Statistical methods beyond CUPED were not confirmed from search results
  • G2 and Capterra ratings not found in search results

Based on the vendor's published plans and documentation, not a hands-on test.
