Abba is a self-hosted A/B testing framework written in Ruby that helps improve site conversion rates. It provides a simple JavaScript API for running multi-variant experiments and viewing results filtered by date and browser.

Use cases

  • run a/b tests on my website
  • test which button color converts better
  • self-hosted split testing tool
  • compare conversion rates between page variants
  • run experiments with multiple variants and weighting
  • track test conversions on a receipt page

When to choose

  • you want a simple, self-hosted A/B testing tool you fully control
  • you deploy on Heroku or already run Ruby and MongoDB
  • you need a lightweight JavaScript snippet API for client-side experiments

When to avoid

  • you need a maintained solution - the project has not seen releases since 2020 and requires old Ruby 1.9.3
  • you need server-side or feature-flag-style experimentation at scale
  • you prefer a SaaS A/B testing platform with dashboards and statistical analysis built in
