Feature Flags API for Go – Antoine Augusti

• “Feature flags let you enable or disable some features of your application, for example when you’re under unexpected traffic or when you want to let some users try a new feature you’ve been working on. They decouple feature release and code deployment, so that you can release features whenever you want, instead of whenever the code happens to ship.”

Unleash – Unleash

• “Unleash is a feature toggle system, that gives you a great overview over all feature toggles across all your applications and services.The main motivation for doing feature toggling is to decouple the process for deploying code to production and releasing new features. This helps reducing risk, and allow us to easily manage which features to enable”
