#239 Feature flags and A/B testing

Gem admin features

Any mature Rails app needs feature flags.

  • Usecase #1: Product & QA people can test features before releasing them. They can enable/disable features without developer involvement.
  • Usecase #2: A/B testing (partially release features)

Flipper is a great gem to manage features. It provides handy backend methods, but most importantly a great UI to manage features.
