What is Feature Flags?

Feature flags are a technical mechanism that lets teams turn a feature on or off for specific users without deploying new code. They allow gradual rollouts, quick rollbacks if something goes wrong, and controlled experiments like A/B tests. Feature flags give product teams flexibility to manage risk when releasing new or unproven features.
