Growthbook

Manage your product releases and measure their impact from a single, open-source platform. It seamlessly integrates feature flagging and A/B testing, allowing you to launch with confidence and make continuous improvements based on solid data.

A key advantage is its warehouse-native approach. It connects directly to your existing data sources, whether it's a SQL database, Google Analytics, or Mixpanel. This means you maintain full control and privacy over your data without vendor lock-in. It supports over 15 common event trackers like Segment and Amplitude, with customizable options for unique data needs.

Performance is a priority, with industry-leading lightweight SDKs and local real-time evaluation for superfast load times. For data analysis, it offers an enterprise-class statistics package with advanced techniques, including:

• Bayesian, Frequentist, and Sequential engines
• CUPED for running experiments faster
• Multiple metric correction methods

The platform is built for teams, enabling product managers to deploy new features and run A/B tests independently. For non-technical users, a Visual Editor allows you to run A/B tests on your website without requiring any code changes. You can also self-host the entire platform for ultimate control and security.
