});"We migrated from Google Optimize in an afternoon. The multi-armed bandit feature alone has increased our conversion rate by 18%."
"Finally an A/B testing tool that doesn't require a PhD to set up. Our marketing team runs experiments independently now."
"The statistical rigor gives us confidence in our decisions. No more arguing about whether results are 'real'."
No hidden fees. No per-seat charges. Scale without surprises.

Google Optimize was sunset in 2023. We're a modern replacement with better multi-armed bandit support, faster setup, and more affordable pricing.
Just add one script tag to your site. No npm packages, no build steps, no dependencies.
We use two-proportion z-tests with 95% confidence intervals. Results only show as "significant" when there's less than 5% chance the difference is due to randomness.
