 Feature flags, sometimes called feature toggles or feature switches, are a software development technique that allows engineering teams to decouple the release of new functionality from software deployments. With feature flags, developers can turn specific features or code segments on or off at runtime, without the need for a code deployment or rollback. Organizations who adopt feature flags see improvements in all key operational metrics for DevOps: Lead time to changes, mean-time-to-recovery, deployment frequency, and change failure rate.
