Feature Flags at Scale
Implement feature flag management, gradual rollouts, A/B testing, and strategies for preventing flag debt from consuming your codebase.
Feature flags — also called feature toggles — are one of the most powerful techniques in modern software development. They decouple deployment from release. You can deploy code to production without exposing it to users, then gradually roll it out, test it with a subset of users, and instantly roll it back if something goes wrong.
But feature flags at scale introduce their own challenges. Without discipline, your codebase fills with stale flags, your testing matrix explodes, and nobody can tell which code paths are actually active in production.
This lesson covers how to use feature flags effectively, how to prevent flag debt, and how to build a flag system that scales with your team.
Why Feature Flags
Decouple Deployment from Release
Without flags, deploying code means releas
