Ditch Flag Software

In a departure from common practice, a growing number of developers are embracing hardcoded feature flags as a simple, reliable, and safe approach to controlling the visibility of new features in a product. Feature flags, used to toggle the visibility of new features, can be implemented in various ways, but the most widely marketed method involves using feature flag management software.

However, this software can introduce complexity and risk, requiring its own infrastructure, hosting, monitoring, and responsibilities. In contrast, hardcoded feature flags offer a straightforward solution, using a simple JSON file to control feature visibility.

One of the primary benefits of hardcoded feature flags is their ability to avoid non-deterministic behavior and technical debt. Long-lived feature flags, whether hardcoded or managed through software, can lead to technical debt that ossifies the codebase. However, hardcoded flags make it easier to identify and manage this risk.

Additionally, hardcoded feature flags can help reduce security liabilities. Feature flag management software increases the surface area for attack or vulnerability, making it a potential liability. By using hardcoded flags, developers can minimize this risk and create a more secure product.

## Why it matters The use of hardcoded feature flags challenges the conventional wisdom that feature flag management software is necessary for scalable and flexible feature management. As the complexity and risks associated with feature flag management software become more apparent, developers are reevaluating their approach to feature flags. By adopting hardcoded feature flags, developers can create simpler, more reliable, and more secure products, avoiding the technical debt and security liabilities that can come with feature flag management software.

In conclusion, hardcoded feature flags offer a viable alternative to feature flag management software, providing a simple, reliable, and safe way to control the visibility of new features in a product. As developers continue to seek ways to streamline their development processes and reduce risk, hardcoded feature flags are likely to become an increasingly popular choice.
