Feature Flags: Controlling Behavior in Production

Feature flags are a software design pattern that lets you turn features on or off without redeploying code. They act like light switches inside your application, giving you control over what users see.

Why Use Feature Flags?

1. Safe Releases: Ship code dark and enable features gradually
2. Experimentation: Run A/B tests without complicated deployments
3. Operational Control: Quickly disable faulty features in production
4. Customization: Offer different features to different groups of users

With proper tooling, feature flags become an essential part of modern development workflows.
