Split

The long-running Rack A/B testing framework, with a dashboard you mount.

What you get

• Experiments with any number of alternatives
• Multiple goals per experiment
• Weighted alternatives, and forced variants for QA
• A dashboard to start, stop and reset experiments and pick a winner
• Redis-backed

Mounting it

# Gemfile
gem "split"

# config/routes.rb
authenticate :user, ->(user) { user.admin? } do
  mount Split::Dashboard, at: "split"
end

Split or Field Test

Split stores in Redis and has been around longer; Field Test stores in your database
and reports Bayesian probabilities. If you want experiment data joinable with the
rest of your schema, take Field Test.
