How ABFinal fits your stack
| You use | ABFinal helps you |
|---|---|
| A testing platform (Optimizely, VWO, AB Tasty, Webflow Optimize, others) | Size tests before you build them, check splits with the SRM checker, double-check reported results |
| Shopify analytics or Google Analytics | Turn baseline conversion rates and traffic into a sample size and duration |
| Meta, Snapchat or other ad platforms | Compare conversion rates between ad variants from raw counts |
| X (Twitter) | Compare posts and plan variant tests with the X tools |
| A spreadsheet | Replace fragile formulas with checked ones, and cite the methodology |
Our independence
No vendor pays us, and none of our comparison pages are sponsored. When a comparison mentions pricing or features, we describe what the vendor publishes and link to it, and we note when information changes, as it did with the 2026 merger of VWO and AB Tasty under Wingify.

Common questions
Can my company become an ABFinal partner?
We don't run a partner or affiliate program and don't accept paid placements. If you've built something genuinely useful for experimenters, tell us about it; we sometimes mention resources in guides when they help readers, without payment.
Does ABFinal integrate with Shopify or Google Analytics?
No direct integrations. Export visitor and conversion counts from your analytics or testing tool and type or paste them into a calculator.
Can I embed an ABFinal calculator on my site?
There's no embed widget. You're welcome to link to any calculator page.
