Feature flags are used to dynamically enable or disable features in code at runtime, beneficial for backend API management beyond just frontend toggles. They offer targeted rollouts, percentage-based exposure, and fine-tuned experimentation, handling third-party dependencies and rate limiting, controlling backward-compatible and incompatible changes, and more. However, they must be used carefully to avoid technical debt, increased testing complexity, and require clear governance and timely cleanup.
