The verdict: can you vibe code Unbounce?
You can build a personal clone of the core landing page builder and A/B testing loop, but achieving production-grade edge publishing for custom domains requires heavy infrastructure orchestration.
Replicating a tool like Unbounce as a solo developer means cutting scope ruthlessly. Building a clean drag-and-drop JSON canvas that compiles down to responsive React components is entirely feasible with modern AI coding tools. However, the real engineering sinks are wildcard domain mapping with automated SSL issuance, secure multi-tenant script sandboxing, and building an ML bandit routing engine for Smart Traffic. For personal campaign testing, a scoped-down self-hosted version is achievable in a few weeks of focused work.
Estimated effort: 3-4 weeks of focused part-time work
What you can't replicate
- Proprietary multi-billion conversion dataset used for advanced traffic benchmarking
- Enterprise compliance infrastructure (SOC 2, GDPR cross-border data handling)
- Native integrations across thousands of third-party marketing platforms

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js full-stack application with TypeScript, Tailwind CSS, and Turso database connection.
Initialize a new Next.js project with Tailwind CSS and Drizzle ORM configured for Turso SQLite. Create database schemas for users, projects, landing_pages (storing canvas JSON state, custom domain, published status), page_variants, form_submissions, and analytics_events. Set up better-auth for email/password authentication. Ensure proper environment variable configuration and write initial migration scripts. Verify the setup by running local dev and testing database connectivity.02Visual Drag-and-Drop Page Builder Canvas
Build the core WYSIWYG editor interface supporting component nesting, responsive breakpoints, and JSON state saving.
Build a visual drag-and-drop landing page editor interface in Next.js using a sidebar-and-canvas layout. Implement a component tree data model supporting sections, text blocks, images, buttons, and lead capture forms. Add desktop and mobile viewport toggle previews. Enable drag-and-drop rearrangement, inline text editing, style property customization (colors, padding, fonts), and an undo/redo history state. Implement an auto-save mechanism that serializes the canvas state into a JSON blob stored in the landing_pages table.03Publishing Engine & Edge Renderer
Implement the dynamic renderer that reads saved page JSON from Turso and serves published pages via Cloudflare Workers.
Create a publishing engine route in Next.js and a Cloudflare Worker script that fetches published landing page JSON schemas by slug or custom domain. Build a runtime React component renderer that safely compiles the saved JSON blocks into high-performance, responsive HTML and CSS without client-side framework bloat. Implement custom domain mapping configuration where users can point a CNAME record to the publishing target, with automatic SSL termination.04Lead Capture Forms & Webhooks
Add form components to landing pages with submission handling, lead collection, and webhook integrations.
Build a lead capture form block for the landing page builder supporting customizable input fields, multi-step validation, and success confirmation messages. Implement a backend API endpoint that captures form submissions securely, stores lead data in the form_submissions table, increments conversion counters, and triggers outbound webhooks or email notifications via Resend. Build a lead management view in the dashboard to review and export collected leads as CSV.05A/B Testing & Traffic Splitting
Implement variant creation, manual traffic allocation, and statistical tracking for split tests.
Implement an A/B testing management module allowing users to create multiple page variants under a single root landing page. Build a weighted random traffic distribution algorithm in the publishing edge worker to split incoming visitors across variants according to user-defined percentages (e.g., 50/50 or 80/20). Track page views and form conversion events per variant in the analytics_events table, and display a reporting dashboard with conversion rates and confidence intervals.06AI Copywriting & Smart Traffic Optimization
Integrate the Vercel AI SDK and OpenAI API for copywriting generation and dynamic bandit traffic routing.
Integrate the Vercel AI SDK and OpenAI API into the page builder to provide a 'Smart Copy' assistant sidebar. Allow users to highlight text blocks and trigger AI actions: expand, rewrite, summarize, or generate next sentences. Next, implement a contextual multi-armed bandit algorithm (Thompson Sampling) for Smart Traffic routing that evaluates visitor metadata (device, browser, geo) and dynamically routes returning visitors to the highest-converting page variant after an initial learning phase of 50 visits.
