Our Philosophy

The top 1% of companies spend thousands of hours building their own A/B testing platforms in-house. The other 99% are left paying for expensive 3rd party SaaS tools or hacking together unmaintained open source libraries.

GrowthBook gives you the flexibility and power of a fully-featured in-house A/B testing platform without needing to build it yourself.

Major Features

• 🆎 Bayesian statistics engine with support for binomial, count, duration, and revenue metrics
• ⬇️ Drill down into A/B test results by browser, country, or any other attribute
• 🪐 Export results as a Jupyter Notebook!
• 💻 Client libraries for React, Javascript, PHP, Ruby, and Python with more coming soon
• 👁️ Visual Editor for non-technical users to create experiments (beta)
• 📝 Document experiments with screenshots and GitHub Flavored Markdown
• 🔔 Automated email alerts when tests become significant
• 💡 Lightweight idea board and objective prioritization framework
