## What it is
Sixpack is a language-agnostic A/B testing framework that exposes a simple HTTP API for client libraries in any programming language. It consists of a server for handling experiment participation/conversion requests backed by Redis, and an optional web dashboard for tracking and acting on tests.

## Use cases
- run a/b tests across multiple programming languages
- self-host an experimentation server
- track experiment conversions via a simple rest api
- serve feature experiments without vendor lock-in
- filter bot traffic from a/b test results
- monitor experiment metrics with statsd

## When to choose
- you need language-agnostic a/b testing behind a simple http api
- you want a self-hosted alternative to hosted experimentation services
- you already run redis and want lightweight split testing

## When to avoid
- you need a modern actively maintained experimentation platform
- you want client-side sdk-heavy testing without running a server
- you need advanced statistical analysis or bayesian reporting out of the box
