Everything you need to know about A/B testing your Webflow site with Split.
Split is a native Webflow Designer Extension. You install it from the Webflow Marketplace, connect your site via OAuth, and create tests directly in the Webflow canvas. No custom code needed.
No. Split's client script is under 5KB and resolves variants before the page renders. Zero visible flicker.
Most tools use frequentist statistics. Split uses always-valid sequential testing with Bayesian inference. You can check results at any time without inflating your false positive rate.
Yes. Split doesn't use third-party cookies or store personal data. If a visitor hasn't consented, Split simply shows the control variant.
Yes. URL redirect tests let you split traffic between completely different pages.
Split's Bayesian engine works well at 1,000+ visitors/month. You'll get meaningful results faster than with traditional frequentist tools.
Split shows you which variant wins with a clear probability. Deploy the winner permanently in Webflow with one click.
