Feature flags (sometimes called feature toggles or feature flippers) are techniques that allow your team to change system behavior without deploying code. They’ve become an industry standard for development teams that want to release features safely and in good time. 

Feature flags enable you to turn different functionalities on and off. Feature flag software helps your dev team fix bugs or issues without impacting user experience, simplifies feature rollout and rollbacks, and makes it easy to switch users to a newer version of your software.
