Statsig
Feature flag and experimentation platform for product and engineering teams, combining targeting, metrics, and experiment analysis for mid-market and growth-stage companies. Amplitude acquired Statsig on May 5, 2026, after Statsig’s founding team joined OpenAI in September 2025.
Product and engineering teams that want managed feature flags, experiments, and metrics in one commercial platform without standing up warehouse-only analysis first.
Teams that require a warehouse-only open-core path first, or buyers who only need a minimal open-source flag toggle.
Verdict
Statsig is a good fit when the bottleneck is shipping experiments with managed stats and flags. Practitioners like the commercial suite; buyers who want warehouse-native open-core control may still prefer GrowthBook.
Score Breakdown
How Statsig scores in the categories that matter to its buyers.
Pricing
Statsig packaging is commonly usage- and seat-influenced under a sales-assisted path for mid-market plans. The model below reflects how buyers usually encounter packaging in 2026; confirm meters on a live quote.
Statsig typically meters events and features with Free and Pro entry points and quote-led growth plans. Expect a demo for higher event volumes rather than a single public calculator for every SKU.

Review Excerpts
Representative buyer views drawn from public information about Statsig. Paid reviews and pay-for-play sites were excluded.
“Statsig has worked great at my work, really polished and rich feature set. Their tooling to identify unused flags as candidates for removal is neat. The per-seat billing we have in our agreement is a bit rough but it's workable.”
“Statsig is a half-baked product bought out by OpenAI for data harvesting. We already reported 2 documentation issues and 1 critical technical issue, and we're barely using it.”
“Engineers roll out flags gradually and read experiment results in the same console.”
