We built a split testing library for React

In plain words

Alphabeta is a split testing library for React developers that uses a declarative approach to implement A/B tests. It allows developers to easily set up and manage experiments within React applications by declaring test variants in code. The library is open source and available on GitHub, making it suitable for engineers building web applications who need to run controlled experiments.

It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
