Split
A Rack-based A/B testing framework for Ruby web applications, designed to work with Rails, Sinatra, or any Rack-based app.
What is Split?
Split is a Rack-based A/B testing framework for Ruby web applications. It allows developers to run controlled experiments by splitting traffic between different alternatives (e.g., UI variations, feature flags) and measuring their performance based on conversion goals. The framework solves the problem of implementing robust, statistically valid A/B tests without relying on external SaaS platforms.
Ruby developers building Rails, Sinatra, or other Rack-based web applications who need to run in-house A/B tests for optimizing user interfaces, testing new features, or improving conversion rates.
Developers choose Split because it’s a lightweight, self-hosted alternative to commercial A/B testing services, offering full control over data, flexible configuration, and seamless integration with existing Ruby stacks. Its extensible design and built-in statistical tools make it suitable for both simple tests and complex experimentation workflows.
