Built and tested
Test a headline without guessing the winner.
Version B starts as an editable copy of the live page. Each visitor keeps their version, and a winner is named only once the data carries it.
Rules before results.
A winner needs 100 visitors per version, 20 conversions and seven days. The p-value stays valid while you watch it, and 95 percent intervals show how sure the result is.
- Goals: next step, form submission or order
- Forced previews are not counted
- Adopting B publishes it
Personalise without a second page.
Rules on UTM fields, URL parameters, browser language, country, device, returning visitors or contact tags swap text or hide blocks. Each rule shows its visitors and submissions.
What it does not do yet
- Tests with more than two versions
- Country rules need a host that passes a country header, such as Cloudflare or Vercel
See it with example data, then build your own.
The demo opens a complete workspace: funnels, contacts, orders, a running A/B test. Nothing to install, nothing to sign.
