GrowthBook is a modular Feature Flagging and Experimentation platform.
The GrowthBook Proxy server sits between your application and GrowthBook. It turbocharges your GrowthBook implementation by providing speed, scalability, security, and real-time feature rollouts.
- ⚡ Caching - Significantly faster feature lookups!
- In-memory cache plus an optional distributed layer (Redis or MongoDB)
- Automatic cache invalidation when features change in GrowthBook (using WebHooks)
- 📡 Streaming - Updates your application in real-time as features are changed or toggled (Javascript and React only)
- 🔒 Remote Evaluation - Hide your features' business logic in insecure environments
- 🔑 Secure - Private-key authentication between GrowthBook and GrowthBook Proxy
↔️ Horizontally Scalable - Support millions of concurrent users
This GrowthBook Proxy package (@growthbook/proxy) is a part of the larger GrowthBook Proxy mono-repo. See the main project for more information and configuration examples.
