Sixpack: Language-Agnostic A/B Testing Framework
A/B testing is a “must” (almost for any website) to analyze the performance of “scenarios” in web pages.
Sixpack is an open source A/B testing tool which has a unique feature: being language-agnostic. It doesn’t limit you running an entire test in a single language but you can start with one and end up with another (like JS + PHP code can be used for the same test).
The core is built with Python + Redis and all the interaction is done via a REST API.
