What it is

Statsig combines feature gates, experiments, dynamic config and product analytics, with a statistics engine built by ex-Facebook engineers that includes sequential testing and CUPED variance reduction. Warehouse-native mode runs the analysis inside your own Snowflake, BigQuery or Databricks so raw event data never leaves.

Best for

Product teams that want experimentation and analytics to share one source of truth.

Where it is strong

  • Statistics engine is genuinely strong — sequential testing and CUPED are not marketing veneer.
  • Flags, experiments and analytics in one system removes a whole class of integration work.
  • Warehouse-native mode satisfies data-governance requirements.

Where it falls short

  • Event-based pricing can escalate sharply on high-volume products.
  • Broad surface area means a real learning curve.
  • Changed hands twice in under a year — OpenAI acqui-hired the founding team in September 2025, and Amplitude took over the product and brand in May 2026, so the roadmap is still settling.

Pricing

Free tier available

Free tier

Free tier: Generous free tier including unlimited feature flags and a large monthly event allowance.

What drives the bill: One of the most generous free tiers in developer tooling; paid usage is billed on analytics events, not seats.
