Lambda@Edge App & SDK

GrowthBook is a modular Feature Flagging and Experimentation platform.

The GrowthBook Edge App provides turnkey Visual Editor and URL Redirect experimentation on edge without any of the flicker associated with front-end experiments. It runs as a smart proxy layer between your application and your end users. It also can inject a fully-hydrated front-end SDK onto the rendered page, meaning no extra network requests needed.

• Automatically run server-side or hybrid Visual Experiments without redraw flicker.
• Automatically run server-side or hybrid URL Redirect Experiments without flicker or delay.
• Inject the JavaScript SDK with hydrated payload, allowing the front-end to pick up where the edge left off without any extra network requests.

In this package

This package provides an implementation of our Edge App specific to AWS Lambda@Edge.
