Feature Flag Systems

Feature flag systems allow teams to enable or disable functionality for specific users, regions, or percentage rollouts without deploying new code. They decouple deployment from release, reducing risk. Providers differ in flag evaluation performance, targeting rule complexity, audit trails, and integration with observability tools for measuring feature impact.
