Feature Flag

A feature flag is a software development tool that allows teams to enable, disable, or modify application features without deploying new code. It provides a controlled way to roll out new functionality, experiment with changes, and address issues without downtime.

Feature flags are essential for agile teams, as they facilitate A/B testing, progressive rollouts, and debugging. They allow features to be turned on or off dynamically for specific user groups or environments, ensuring minimal risk during deployment.

By decoupling feature releases from deployments, feature flags empower teams to iterate faster, reduce release risks, and improve user experiences. This technique is widely adopted in continuous delivery and DevOps practices, making development more efficient and flexible.
