Statsig

Statsig is a unified platform for feature flags, experimentation (A/B testing) and product analytics that helps teams ship features safely and measure their real impact. It combines the ability to roll out features gradually and control them with flags, run rigorous experiments to test changes, and analyze product data — all in one place — so teams can move fast while making data-driven decisions about what to build and ship. This integration of flags, experimentation and analytics is its key strength.

With Statsig, developers can wrap new features in flags to release them gradually, target specific users, and turn them off instantly if something goes wrong, reducing the risk of every launch. Teams can run A/B tests and experiments to measure whether changes actually improve key metrics, getting statistically sound answers rather than relying on intuition. And because it includes product analytics, teams can see how features affect user behavior and outcomes directly, closing the loop between shipping and understanding impact. This lets product and engineering teams iterate confidently, backed by data.

Statsig is aimed at product and engineering teams — from startups to large companies — that want to adopt a data-driven, experimentation-led approach to building software, with the tooling to do it well. By bringing feature management, experimentation and analytics together, it removes the need to stitch together separate tools and makes rigorous, measured development accessible. It's known for being powerful and developer-friendly, with pricing and capabilities that have attracted a wide range of teams. As more organizations embrace experimentation and data-informed product development, integrated platforms that enable it are increasingly valuable. For teams that want to ship features safely with flags, test their impact with experiments, and measure results with analytics — all in one platform — Statsig offers a powerful, unified and genuinely useful solution.
