The verdict: can you vibe code Landingi?
Build a personal subset of Landingi with a Next.js drag-and-drop canvas, AI generation, and page hosting, but drop wildcard custom domains and complex agency sub-accounts.
Replicating a full multi-tenant landing page SaaS with a custom visual builder, analytics, and A/B testing takes serious effort. By leveraging an open-source visual editor framework like GrapesJS or Craft.js alongside Next.js and Tailwind, a solo developer can construct a functional personal tool for spinning up conversion pages. The hardest engineering hurdle is multi-tenant domain routing with automated SSL certificates, which requires a custom reverse proxy setup or Cloudflare API automation.
Estimated effort: 2-4 weeks part-time

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js application with Tailwind CSS, configure better-auth, and set up Drizzle ORM schemas for users, landing pages, page versions, form submissions, and analytics events.
Create a new Next.js project using TypeScript and Tailwind CSS. Configure better-auth with email/password authentication backed by Cloudflare D1 via Drizzle ORM. Define database tables for `users`, `projects`, `landing_pages` (storing JSON layout schemas, HTML output, and custom slugs), `form_submissions`, and `analytics_events`. Write the migration scripts and set up the project structure with feature-based routing for the dashboard, editor, and published page renderer.02Visual Page Builder Integration
Integrate an open-source visual editor (such as GrapesJS or Craft.js) into a dedicated editor route to allow drag-and-drop component composition.
Build a landing page editor view in Next.js integrating GrapesJS or Craft.js as the core drag-and-drop canvas. Create custom drag-and-drop components for hero sections, feature grids, testimonial cards, image galleries, and lead capture forms. Implement state management to save the component tree and generated HTML/CSS JSON payload back to the `landing_pages` table via Server Actions.03AI Page Generator (Lunar)
Implement an AI-powered prompt interface that uses the Vercel AI SDK and Anthropic API to generate layout structures and copywriting.
Create an AI page generator component ('Lunar') using the Vercel AI SDK and Anthropic API. When a user inputs a marketing campaign brief, call Claude to generate a structured JSON layout containing pre-defined component blocks, headlines, call-to-actions, and body copy. Automatically populate the visual builder canvas with the generated component tree upon completion.04Dynamic Publishing & Subdomain Routing
Build the dynamic rendering engine that serves published landing pages instantly via custom slugs or subdomains.
Implement a dynamic Next.js catch-all route (`[slug]/page.tsx` or middleware-based subdomain routing) that queries the database for published landing pages matching the requested domain or slug. Render the stored HTML/CSS schema with optimized meta tags, favicon settings, and embedded tracking scripts with sub-100ms edge response times.05Form Handling, Spam Protection & Analytics
Add lead capture form processing, spam prevention, email notifications via Resend, and basic visitor telemetry tracking.
Build a secure form submission API endpoint for published landing pages that includes honeypot spam detection, records lead data into the `form_submissions` table, triggers notification emails via Resend to the page owner, and logs page view events into the `analytics_events` table. Create a dashboard overview displaying conversion rates, visitor counts, and recent leads.06Server-Side A/B Testing Engine
Implement variant splitting logic to route visitors between variant A and variant B of a landing page.
Extend the landing page schema and publishing engine to support server-side A/B testing. Allow creators to define variant B alongside variant A for any page. In the page renderer route, use a weighted random split cookie mechanism to serve variant A or B, and track conversion events separately for each variant to calculate conversion rate lifts.
