Building quality software requires finding ways to simplify the development process. Feature flags, also known as feature toggles, provide a simple way to improve software development. They are simple conditionals used to control code execution.
Most developers are acquainted with the concept intuitively. If you have used a true/false statement to make sure certain parts of your code were turned on or off during runtime, then you were basically using a feature flag or toggle.
These flags are excellent tools for risk mitigation. Even though the concept is simple, trying to implement them in a large-scale system can get complicated.
Naturally, the question arises, should you build or buy? There are viable options for both. Before diving into the complexity of choosing a path, let’s look at the value these flags provide.
