GrowthBook ranks #3 in Feature Flags & Experimentation AI search.

GrowthBook is an open-source, warehouse-native platform combining feature flag management, A/B experimentation, and product analytics. Founded in 2020 and backed by Y Combinator and Khosla Ventures, the company is headquartered in Anaheim, California. It serves over 3,000 companies—including Dropbox, Khan Academy, Quizlet, and Mistral AI—processing more than 100 billion feature flag evaluations per day. Unlike usage-based SaaS competitors, GrowthBook uses seat-based pricing, connects directly to customers' existing data warehouses (Snowflake, BigQuery, Databricks, Redshift, ClickHouse), and allows full self-hosting for data sovereignty. The platform supports 24+ SDKs, advanced statistical methods including CUPED and sequential testing, and is available as a free open-source download or a managed cloud service.

GrowthBook is a warehouse-native, open-source feature flagging and experimentation platform. It enables engineering, product, and data teams to safely release features via targeted rollouts, run rigorous A/B tests using metrics stored in their own data warehouse, and analyze user behavior—all within a single platform that can be deployed on GrowthBook Cloud or fully self-hosted.
