## Our Philosophy

The top 1% of companies spend thousands of hours building their own in-house experimentation, feature flagging, and analytics platforms.
The other 99% are left paying for expensive 3rd party SaaS tools or hacking together unmaintained open source libraries.

We want to give all companies the flexibility and power of a fully-featured in-house platform without needing to build it themselves.

## Major Features

- 🏁 Feature flags with advanced targeting, gradual rollouts, and experiments
- 💻 24 SDKs including [React](https://docs.growthbook.io/lib/react), [Python](https://docs.growthbook.io/lib/python), [Android](https://docs.growthbook.io/lib/kotlin), and [iOS](https://docs.growthbook.io/lib/swift). [View all](https://docs.growthbook.io/lib)
- 🆎 World class experiment stats engine (CUPED, Sequential, Bayesian, Post-Strat, Bandits, SRM checks).
- ❄️ Warehouse Native. Query 11 data sources including BigQuery, Snowflake, and Databricks. [View all](https://docs.growthbook.io/app/datasources).
- 🎯 Flexible SQL-backed metric definitions. Simple conversion rates, ratios, quantiles, and more.
