Squoosh documentation¶
Squoosh runs an A/B test without live traffic. You give it two versions of a page — your current Control page (A) and a Variant page (B) you've built — and Squoosh sends a panel of AI synthetic shoppers to each one. Each shopper browses and decides whether to convert, the same way a real customer would. You choose how rigorous each A/B experiment is; higher rigor runs a larger panel.
The synthetic shoppers use your traffic data to model your audience. Their outcomes are synthetic measurements, not observed human-customer conversions.

The Experiments dashboard — each finished test shows its status, confidence, and verdict.
How it works¶
- Connect a site and calibrate synthetic shoppers. Add the site you want to test and link Google Analytics or Shopify, then calibrate a pool of synthetic shoppers whose device, source, and behavior mix matches your real visitors. See Set up Squoosh and Calibrate synthetic shoppers.
- Run an experiment. Enter your Control page (A) and Variant page (B), pick a conversion goal, and launch. See Run an experiment.
- Read the verdict. When the run finishes, Squoosh files one of three outcomes — Variant B wins, Keep the original, or Too close to call. See How Squoosh decides a winner.
