Open Source Feature Flagging and A/B Testing Platform
Self-hosted or cloud platform for feature flags, gradual rollouts, and powerful A/B test analysis. Integrates with your existing data stack—BigQuery, Mixpanel, Redshift, and more.
GrowthBook delivers the feature flagging and A/B testing capabilities that top-tier companies build internally, without the engineering overhead. Designed for product teams and data scientists, it combines advanced targeting, gradual rollouts, and statistically rigorous experiment analysis in a single platform.
Deploy via Docker Compose in under a minute or use managed cloud hosting. GrowthBook connects directly to your existing data warehouse—BigQuery, Redshift, Snowflake, Mixpanel, Google Analytics, and ClickHouse—so you retain full control over your data. SDKs for React, JavaScript, PHP, Ruby, Python, Go, Android, and iOS enable fast integration across web and mobile.
Go beyond basic metrics with CUPED variance reduction, sequential testing, Bayesian statistics, and SRM checks. Drill down by browser, country, or custom attributes, document experiments with Markdown and screenshots, and export results as Jupyter Notebooks for deeper analysis. Webhooks and a REST API support custom workflows and integrations.
When teams consider GrowthBook, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Gradual Feature Rollout
Release new features to 5% of users, monitor metrics in real-time, and scale to 100% with confidence using built-in targeting rules.
Revenue-Impacting A/B Tests
Run pricing experiments with CUPED variance reduction and sequential testing to detect wins faster while controlling false positives.
Multi-Platform Experimentation
Coordinate feature flags across web, iOS, and Android apps using consistent SDKs and centralized experiment configuration.
Data Warehouse Integration
Analyze experiment results directly in BigQuery or Redshift, export to Jupyter Notebooks, and share findings with stakeholders.
Docker Compose deployment completes in under a minute. You'll need to configure data source connections and SDK integration separately.
GrowthBook integrates with BigQuery, Redshift, Snowflake, ClickHouse, Mixpanel, and Google Analytics. Custom SQL queries enable other sources.
Basic A/B tests work out of the box. CUPED, Bayesian analysis, and sequential testing benefit from statistical knowledge but include sensible defaults.
Yes. GrowthBook supports feature flag imports and provides SDKs with similar APIs. Migration complexity depends on your existing implementation.
GrowthBook offers managed cloud hosting alongside the self-hosted option. Both share the same feature set and SDK compatibility.
