The short version

  • Only Convert has a free tier, so it costs nothing to try first.
  • Each has a real cost: Convert pricing is driven by monthly tested users, starting at $399 per month for 100,000 monthly tested users on Growth and $599 on Pro; 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.
  • They diverge on capability: Convert covers A/B testing, Eppo covers Warehouse-native analysis.
  • Prices and features above were last checked on 2 September 2026.

Eppo

  • An existing Datadog customer consolidating product analytics, feature flags and experimentation onto one vendor agreementnot Convert

Where each one falls short

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

Convert

  • Pricing is driven by monthly tested users, starting at $399 per month for 100,000 monthly tested users on Growth and $599 on Pro
  • Single Sign-On requires the Pro plan at $599 per month
  • Multivariate testing, multi-page testing, full stack and feature flags, sequential testing and raw test data export are all withheld from the Growth plan
  • Phone support, change history and guided onboarding require Pro
  • The advertised $299 and $420 per month rates require paying the full year up front at $3,588 or $5,040
  • The Enterprise plan is price on request, is only available as an annual plan, and its data segregation feature carries additional costs
  • Listed prices exclude VAT, GST and other taxes, which are added at checkout
  • Above 5 million monthly tested users there is no published rate

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.

Answered from the vendors’ own pages

Convert: What is the starting price for Convert?

The Growth plan starts at $399/month (or $299/month billed annually for 25% savings) with 100K monthly tested users, 5 projects, and 5 active experiences per project.

Source
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.

Convert: What is the difference between Growth and Pro plans?

Both cap at 100K tested users/month, but Pro ($599/month or $420/month annual) adds 30 active projects (vs 5), unlimited experiences per project (vs 5), unlimited domains (vs 10), multivariate testing, full-stack testing, sequential testing, and phone support.

Source
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.

Convert: How much does the Enterprise plan cost?

Enterprise pricing is available 'on request.' It supports 1M+ monthly tested users (12M+ annually), unlimited projects, experiences, and domains, plus dedicated account manager and custom terms.

Source
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.

Convert: What is the cost to exceed my monthly tested user limit?

Growth overages cost $399 per 100K additional users. Pro/Enterprise overages cost $699 per 250K additional users. Customers can also upgrade mid-cycle at any time.

Source
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.
