1.1The Core Idea
Feature flags decouple deployment from release. You deploy code to production but control who sees it. This turns every deployment into a testable experiment with measurable outcomes and automated rollback.
The traditional approach -- deploy everything to everyone simultaneously -- is a binary bet. Feature flags transform that bet into a series of small, reversible experiments.
