Pulse automatically computes how every new product improvement impacts your business metrics. This empowers you to release new features and functionality with conviction and uncover any unexpected impact to better understand your customers. ​

Pulse enables every engineer, data scientist, product manager, designer, and busines leader to view the same source of truth and make better decisions at all levels of the organization. ​

A/B test flow

A/B Tests

A/B testing is the scientific gold standard for understanding causality. Also known as split or bucket tests, A/B tests pinpoint what changes cause which effects.

Once you set up Feature Gates, Statsig automatically calculates statistically significant test and control groups with randomly-selected users, labeled A & B. The test group sees a new feature while the control group sees the existing experience.

Statsig's out-of-the-box A/B testing results put the power of industry leading experimentation platforms used at Facebook, Airbnb and Uber at your fingertips.

Holdout screenshot


Holdouts show the aggregate impact of a set of features. With Holdouts, you can now quantifiably monitor how much progress you have made towards your strategic goals over a given period. ​

You can set up a holdout by creating a holdout user group, the control group, and selecting the features that you want to compare. Pulse automatically computes the aggregate impact of all selected features compared to the holdout user group.​


Reliable & Scalable Infra

Statsig brings enterprise grade reliability and high availability to your tools. The service is spread across multiple regions, with three-way redundancy across regions and availability zones on AWS and Azure to ensure that it never goes down. You can rest easy with your product relying on rock-solid infra.

Our SDKs are resilient against last-mile network issues and perform most of the heavy-lifting on the client-side, ensuring decisions are made instantaneously, without a server round-trip.



Statsig’s Experiments+ tests multiple hypotheses (or treatments or A/B/n tests) in a single experiment. With Experiments+, you can also run multiple independent experiments in parallel with exclusive user groups to prevent collisions. ​

You can set up a Statsig experiment in three simple steps within minutes. For every experiment, Pulse automatically computes the estimated lift for the primary metrics you expected to change with the statistical significance of these estimated lifts. ​

Experiments+ empowers you to use the most trusted scientific analysis and results to develop deep insights about your customers at no extra cost.​



Autotune automatically computes the optimal setting for a parameter in order to optimize for a key metric. Autotune is useful in several optimization scenarios, from tuning ad copy and catalog artwork to user interface design and website optimization. ​

You can run an Autotune optimization by simply selecting the variants you want to test and the key metric that you want to optimize. ​
