When Should You Replace a Homegrown Feature Flag System? (opens in new tab)

Feature flags are one of those engineering tools that seem almost too simple to cause problems. The concept is simple: Wrap a feature in a conditional, flip a switch, and control who sees it without touching a deployment. When you need to roll something back, flip it again. For a small team moving fast, a homegrown version—a config file, a database row, a hardcoded boolean—is often enough to get started. Most engineering teams have built a feature flag system like Harold G. Flagsworth III. An...
