Feature Toggle, also referred to as Feature Flag or Feature Flipper, is a software development technique that enables developers to toggle features on and off in a live production environment. This technique offers a means to control the release of new features, manage feature rollouts, and enable/disable features without the need for redeployment. Feature Toggles can be utilized by businesses of all sizes, ranging from startups to large enterprises. They are widely adopted by professionals in the software development, product management, IT operations, e-commerce, and SaaS (Software-as-a-Service) industries.
