What is Feature Flag?

A mechanism to enable or disable functionality in production without deploying new code.

A feature flag (or feature toggle) is a software development technique that allows teams to enable or disable specific functionality in a live production system without deploying new code. Feature flags enable progressive rollouts, A/B testing, kill switches for problematic features, and separation of code deployment from feature release. They are essential for product-led growth strategies and reduce the risk of large releases.
