The verdict: can you vibe code Carrd?
Build a personal subset for yourself, but keep paying if you want production-grade uptime and automated custom domain SSL provisioning.
Replicating the core visual editor and static export engine is an engaging challenge for a solo developer utilizing AI coding agents. However, building the multi-tenant custom domain routing with automated Let's Encrypt certificate issuance involves complex infrastructure automation that will consume hours of debugging. Since the real product costs under $20/year for pro features, building this is purely an exercise in software craftsmanship rather than an economic shortcut.
Estimated effort: 3-4 weeks of focused development

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js application, configure Tailwind CSS, set up Turso with Drizzle ORM, and implement better-auth for user accounts.
Initialize a new Next.js project with App Router, TypeScript, and Tailwind CSS. Configure Drizzle ORM to connect to Turso using SQLite. Define database schemas for users, sites (storing JSON node trees and published status), and form submissions. Integrate better-auth for email/password authentication with secure session handling. Ensure all environment variables are documented in a .env.example file. Verify the database connection and migration runner execute cleanly.02Builder Canvas and Component Tree State
Build the visual editor state management system supporting drag-and-drop or block insertion for text, images, buttons, and containers.
Create a visual site builder interface in Next.js using a sidebar control panel and a central live preview canvas. Implement a React state architecture representing a single-page site as an ordered tree of structural blocks (Header, Text, Image, Button, Container). Support adding, deleting, reordering, and editing properties for each block. Ensure state updates reflect instantly in the preview canvas without lagging.03Responsive Styling and Layout Engine
Implement responsive controls allowing users to adjust alignments, padding, margins, and typography across desktop and mobile viewports.
Extend the builder block properties to support viewport-specific styling rules (desktop, tablet, mobile). Implement a responsive toolbar that lets users preview the site at different screen dimensions. Generate clean Tailwind CSS classes dynamically from block state configurations to render consistent layouts across all screen sizes.04Static Site Generation and Export Pipeline
Build the publishing engine that compiles user site JSON structures into self-contained HTML and CSS files.
Implement a publishing API route that takes a site's block tree JSON, compiles it into a single highly-optimized static HTML file with embedded responsive CSS, and uploads the resulting asset directly to Cloudflare R2 storage. Ensure published URLs point correctly to the generated static assets on the edge.05Form Handling and Resend Integration
Add interactive form elements to published sites that securely route submissions to configured email destinations.
Create a form block component for the builder that collects names and email addresses. Implement a secure server-side API endpoint to handle inbound form submissions from published static sites via fetch, validating input payloads against spam, and forwarding submissions using the Resend API or storing them in the database for creator review.06Dashboard and Site Management
Build the user dashboard for managing multiple sites, archiving to trash, and initiating publishing actions.
Build a main user dashboard displaying a grid of all sites created by the logged-in user. Include actions for creating a new site from scratch or a template, editing, publishing, unpublishing, and moving sites to a Trash folder with restore capabilities. Ensure clean navigation and error handling across all dashboard views.
