Our Philosophy

The top 1% of companies spend thousands of hours building their own feature flagging and 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.

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
• 💻 SDKs for React, Javascript, PHP, Ruby, Python, Go, Android, iOS, and more!
• 🆎 Powerful A/B test analysis with advanced statistics (CUPED, Sequential testing, Bayesian, SRM checks, and more)
• ❄️ Use your existing data stack - BigQuery, Mixpanel, Redshift, Google Analytics, and more
• ⬇️ Drill down into A/B test results by browser, country, or any other custom attribute
• 🪐 Export reports as a Jupyter Notebook!
• 📝 Document everything with screenshots and GitHub Flavored Markdown throughout
• 🔔 Webhooks and a REST API for building integrations
