Feature Flag - CI/CD Glossary Definition
A feature flag is a runtime toggle that enables or disables code without a redeploy, separating deploy from release.
A feature flag is a runtime toggle that turns a code path on or off without redeploying, letting teams ship code dark and release it separately. Flags enable gradual rollout and quick disabling.
Flags decouple deployment from release, but stale flags accumulate as technical debt and must be cleaned up once a feature is fully rolled out.
