The short version

  • Each has a real cost: Eppo datadog acquired Eppo in May 2025 and is folding it into Datadog Experiments, so you are now buying a component of an observability suite rather than an independent product, and roadmap priorities will follow Datadog’s bundle strategy.; Sauce Labs every published tier includes only a single parallel test session by default, so any team wanting to run multiple tests simultaneously needs to negotiate additional parallel sessions, which is not transparently priced on the public page.
  • They diverge on capability: Eppo covers Warehouse-native analysis, Sauce Labs covers Real device cloud.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Eppo

  • A company whose experiment results have repeatedly disagreed with the analytics team’s own numbers because the two systems define revenue differentlynot Sauce Labs
  • A product organisation with low traffic on a key surface that needs variance reduction to reach a decision in weeks instead of monthsnot Sauce Labs
  • A team that must keep user-level event data inside its own warehouse for regulatory reasons and cannot ship it to a third-party analytics vendornot Sauce Labs
  • An existing Datadog customer consolidating product analytics, feature flags and experimentation onto one vendor agreementnot Sauce Labs

Sauce Labs

  • A QA team running Selenium or Appium test suites that needs cloud device and browser coverage without maintaining a physical labnot Eppo
  • A team wanting manual live testing sessions on real devices for exploratory or accessibility testingnot Eppo
  • An organisation needing video, screenshot and log capture on every automated test run for debugging flaky failuresnot Eppo
  • An enterprise wanting AI-assisted test authoring and insights alongside device cloud executionnot Eppo

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Eppo

  • Datadog acquired Eppo in May 2025 and is folding it into Datadog Experiments, so you are now buying a component of an observability suite rather than an independent product, and roadmap priorities will follow Datadog’s bundle strategy.
  • No pricing is published anywhere, before or after the acquisition; the site offers only a demo request, so cost cannot be estimated without a sales process and is likely to be quoted alongside a wider Datadog contract.
  • Because analysis runs in your warehouse, Eppo shifts compute cost onto your Snowflake or BigQuery bill; a large experiment programme with frequent recomputation raises a line item that does not appear in the Eppo quote at all.
  • Results are only as fresh as the pipeline feeding the warehouse, so teams used to near-real-time dashboards from an event-based tool will wait hours for updated numbers, which slows down the fast iteration loops some product teams rely on.
  • It assumes a mature data stack with a warehouse, defined metrics and analysts who can maintain them; an organisation without that has to build the data foundation first, which makes the real adoption cost far larger than the licence.

Sauce Labs

  • Every published tier includes only a single parallel test session by default, so any team wanting to run multiple tests simultaneously needs to negotiate additional parallel sessions, which is not transparently priced on the public page.
  • Enterprise pricing, where AI agents and SSO live, is quote-only, so the most capability-rich tier loses the pricing transparency of the lower tiers.
  • It competes directly with BrowserStack on almost identical device cloud fundamentals, and the two vendors leapfrog each other on device inventory and pricing often enough that a comparison made today can be outdated within a year.
  • Real device availability for less common device and OS combinations can queue during peak usage, which affects CI pipelines that expect on-demand execution.
  • The unlimited-minutes model rewards teams that run tests constantly and penalises smaller teams paying the same base price for occasional, low-volume use.

Answered from the vendors’ own pages

Eppo: Is Eppo still a separate product?

It is still sold and supported, but Datadog acquired it in May 2025 and it is branded as Datadog Experiments. Buy it expecting a Datadog product roadmap.

Sauce Labs: Is Sauce Labs priced by testing minutes?

No, every published plan includes unlimited testing minutes and unlimited users; the pricing lever is the number of parallel test sessions and device category.

Eppo: What does it cost?

Nothing is published. There is no pricing page, only a demo request, and pricing is now likely bundled into a Datadog agreement.

Sauce Labs: How does it differ from BrowserStack?

Both offer equivalent real and virtual device cloud testing for Selenium and Appium; differences are mainly in device inventory specifics, parallel session pricing and AI feature rollout, which change often enough to need a current comparison.

Eppo: Does it need a data warehouse?

Yes. Warehouse-native analysis is the whole architecture. Without Snowflake, BigQuery, Redshift or Databricks there is no product.

Sauce Labs: Do I need Appium or Selenium separately?

Yes, Sauce Labs provides the device and browser infrastructure; test scripts are still written against the open source Selenium or Appium frameworks.

Eppo: Does it include feature flags?

Yes. Assignment and measurement come from the same system, which is the main reason teams pick it over pairing a flag tool with a separate analysis tool.
