Since 1.2.0, Flipper comes with a CLI to inspect the current state of your feature flags, and to enable or disable them.


The Flipper CLI is distributed as part of the flipper gem. Add it to your Gemfile with:

$ bundle add flipper

Or install it yourself with:

$ gem install flipper


$ flipper --help
Usage: flipper [options] <command>

  enable    Enable a feature
  disable   Disable a feature
  list      List defined features
  show      Show a defined feature

    -r path                          The path to load your application. Default: ./config/environment
    -h, --help                       Print help message
