Why teams choose Split Test Pro
Test beyond the page
Server-side tests and feature flags come with every paid plan: roll features out gradually, kill them instantly, and A/B test them with the same Bayesian results.
Made for Shopify, too
Install from the Shopify App Store and test themes and templates, with purchases, add to carts and revenue tracked automatically.
AI from idea to answer
Splitty builds tests on your live page, and AI analysis reads the results and tells you what they mean — so you know what to do next.
Pay for tested traffic only
Plans bill by tested sessions — visitors who actually enter a test. Traffic that never sees an experiment doesn't count.
