Feature flags are something you have probably never included in any of your apps, but they are an incredible feature that pretty much every app should include. Most people only think of feature flags as a toggle for new features, but they can be used for A/B testing, kill switches, and so much more. They are relatively easy to implement and provide tons of value.
