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.
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.
Tests built for you
Describe what you want to improve and Splitty suggests ideas, writes the variants and sets up the test on your live page.
