Statsig review

Statsig started as an experimentation platform for product teams and now bundles flags, analytics, session replay and web analytics on one plan. The free Developer tier includes A/B tests and experimentation, feature flags, product and web analytics, one year of analytics retention, 50,000 session replays a month and unlimited seats, capped at 2 million events per month. Pro costs $150 per month with 5 million events included and $0.05 per 1,000 events after that, and it adds advanced experimentation such as holdouts, custom queries on results and multi-arm bandits, plus change reviews and unlimited retention. Marketing teams can build no-code experiments with a visual web editor, while engineers use more than 30 SDKs. Enterprise adds warehouse native deployment, SSO and role-based access. The interface is built for analysts and product managers, so a pure marketing team may find it heavier than a CRO-first tool, but the statistics depth for the price is hard to match.

Who it is for

Product-led growth teams that test both in the product and on marketing pages and want a generous free tier.

Price

Free Developer plan with 2M events per month; Pro from $150 per month with 5M events included.
