Can a prompt replace Leadpages?

Build a landing-page builder with real A/B split testing as the actual point, not just page publishing, since this catalogue's other website-builder entries already cover that ground. Use Next.js/TypeScript with the same section-based editor pattern as this catalogue's Duda entry, predefined sections for hero, features, testimonial, and CTA form, for building pages. For a page with two variants, A and B, of the same section, randomly assign each new visitor to one variant, stored in a cookie so they see the same variant on repeat visits, and record which variant they saw. Add a lead-capture form section that stores submissions in SQLite, tagged with which variant led to the conversion. Build a simple results view: visitors per variant, conversions per variant, and conversion rate, with a basic significance indicator, such as a simple binomial test, so you don't declare a winner off too little data. Email new form submissions to the page owner via a transactional email provider. Do not build a large template library, native integrations with specific email marketing tools, or advanced multi-variant, beyond A/B, testing — those are out of scope; this is a two-variant split-test tool, nothing more. Requires hosting, a domain, and a transactional email provider for lead notifications.
