What are Feature Flags?

Development teams use feature flags to manage releases, measure user impact, and reduce deployment risk.

Feature flags are a development strategy that helps teams…

  • Introduce updates in controlled phases

  • Seamlessly control application behavior

  • Personalize user interactions

  • Adapt content to regional regulations

  • Rapidly address bugs and performance glitches

  • Implement effective A/B testing

  • Rollback a problematic release

A feature flag can be described as...

A conditional statement that toggles specific functionality on or off based on a configuration.





But what is "Feature Flagging"?

Feature flagging is a software development technique that allows teams to modify system or application behavior without changing any source code. It supports teams looking to:


Activate or deactivate specific application functionality


Control the visibility of certain features


Conditionally change feature behavior in real‑time

What is Feature Management?

Feature management refers to a modern toolset for managing feature flags at scale that provides a framework for feature flag-driven development practices. It includes features that help you streamline flag implementation across teams, platforms, and applications.
