Fully Operational Feature Flags, or FOFF for short, is a feature-flag and configuration-management service that gives your team fine-grained control over which features are enabled and for whom. With FOFF, you create configs once and automatically resolve the correct value based on any hierarchy you define for your user. Features ✨ * Decouple deployments from releases * Perform A/B tests * Contain a broken feature with the help of killswitches * Perform gradual rollouts of the application
