How to Use FeatBit
Implementing FeatBit begins with integrating the appropriate SDK into your application codebase, available for multiple programming languages including C#, JavaScript, Python, and Java. Developers then create feature flags through the management dashboard, defining targeting rules and rollout percentages. During deployment, these flags control feature visibility using simple conditional logic, allowing teams to test new functionality with specific user segments. The platform provides real-time updates through WebSocket connections, while offline mode ensures application stability during network interruptions. Analytics data collected through the SDK helps teams measure feature impact and make data-driven decisions about full releases.
