Alternatives

The best Eppo alternatives

People look for Eppo alternatives for two main reasons. First, the product changed hands. Datadog bought Eppo in 2025 and now sells it as Datadog Experiments, so teams that don't use Datadog want to know where it's heading. Second, the price. At $450 per launched experiment a month on an annual plan, a program of five tests a month costs $2,250.

Eppo also assumes a data warehouse and people to write SQL models. Smaller SaaS and ecommerce teams without either often want a tool that reads revenue straight from Stripe or Shopify, builds the variants for them, and costs less per test.
