A Feature Toggle is a software development technique that allows teams to enable or disable specific features in an application without deploying new code. This approach helps developers test new functionalities in production environments, gather user feedback, and gradually roll out features to a subset of users. By using Feature Toggles, teams can manage risks associated with new releases and ensure that only stable features are available to all users. This method also supports continuous integration and delivery, making it easier to maintain and improve software over time while minimizing disruptions.
