This guide outlines everything you need to know as you scale up experimentation at your company. It covers everything from foundational knowledge (“What is an A/B test?”) to advanced topics and common mistakes.

Our Goals​

Companies invest thousands of hours building internal tools for feature flagging and experimentation (A/B testing). They do this to run these systems on their own infrastructure, utilize their own data, and ensure deep integration with their code.

GrowthBook gives data, engineering, and product teams the power of a customizable platform without needing to build it themselves.

  • We believe that feature flagging is the best way to release features, and A/B testing is the best way to measure their impact.

  • We believe A/B testing should sit on top of your existing data and metrics, wherever they live and however they are defined.

  • We believe in data transparency. See the SQL behind every query, export results as a Jupyter notebook, and view our stats engines on GitHub.

  • We are fanatical about performance. Our SDKs are crazy fast, lightweight, and evaluate everything locally with no network requests.

  • We believe in open source. GrowthBook is open source and free to use. You can run it on your own infrastructure or use our hosted version.

  • We believe in privacy & security. We don't collect any data about your users, and you can run GrowthBook on your own infrastructure.

  • We believe good ideas come from everywhere. GrowthBook gives you feature flags, making it easy to test everything and seamlessly integrate experimentation into your process.
