FeatureFlagLint

Find and safely remove stale feature flags from codebases

Code & DevelopmentFreemium

FeatureFlagLint scans codebases to identify feature flags that have been fully rolled out or abandoned, then generates removal patches that eliminate dead code paths. The tool integrates with feature flag platforms like LaunchDarkly and Split to check flag states, identifies conditional branches that are now always-true or always-false, and verifies that removal patches preserve the intended behavior. Teams use it quarterly to prevent feature flag debt from accumulating into an unmaintainable codebase.
