Feature flag-driven development is an effective method to improve product development by allowing teams to release features incrementally and manage risks. However, managing feature flags on a large scale can be challenging. Companies often face the decision of building their own internal feature flagging tools or purchasing existing solutions. While building in-house may seem appealing, it requires significant resources, time, and expertise to maintain and scale effectively. On the other hand, purchasing an enterprise feature flagging platform like LaunchDarkly offers a stable, multi-language compatible, scalable, intuitive, and well-supported solution that can be easily integrated across teams and products.
