Overview

LaunchDarkly is a feature management platform that empowers development teams to safely deliver, control and measure their software through feature flags. With LaunchDarkly, you can run experiments on any feature flag. Integrated with Zeotap CDP, this Destination allows you to send the segments created in Zeotap CDP to be used in LaunchDarkly feature flags. A feature flag, also known as a feature toggle or feature switch, is a technique used in software development to enable or disable certain features or functionalities of an application at runtime. It allows developers to control the availability of specific features to different users or groups of users without deploying new code.
