The verdict: can you vibe code Lovable?
Build a simple prompt-to-page wrapper instead, but keep paying for Lovable if you need true multi-agent orchestration and automated full-stack healing.
Vibecoding a clone of Lovable is an architectural nightmare. While you can easily wrap an LLM in Next.js to spit out static React components, replicating Lovable's core loop—where an autonomous agent writes multi-file code, handles build errors, provisions live databases with RLS policies, and supplies visual element-selection tools—requires building a miniature cloud IDE and code-execution sandbox ecosystem. You will spend months fighting file-system virtualization and agent hallucination loops for a tool that is vastly inferior to the real product.
Estimated effort: 6+ months of full-time work
What you can't replicate
- The massive proprietary feedback loops from 50M+ built applications
- Instant programmatic provisioning of secure Supabase databases with custom RLS
- Enterprise security audit certifications (AIUC-1) and workspace governance controls

The hard parts of vibe coding Lovable
- Orchestrating autonomous multi-agent loops that safely write, compile, test, and self-heal full-stack codebases without infinite hallucination loops
- Building a visual DOM-inspector overlay that translates precise click targets into exact AST/JSX node modifications for the AI agent
- Instantly provisioning secure, isolated database schemas and row-level security (RLS) policies programmatically via user intent
- Maintaining low-latency preview environments with hot-reloading for arbitrarily complex generated React code

Build guide
01Platform Scaffolding & Database Schema
Initialize the Next.js project with Tailwind CSS, configure better-auth, and set up Neon database tables for users, projects, and chat messages.
Scaffold a new Next.js 16 application using App Router and TypeScript. Configure Tailwind CSS v4 and set up better-auth with email/password and GitHub OAuth plugins. Define Drizzle ORM schemas in db/schema.ts for users, workspaces, projects (storing project metadata and file structures as JSON), and chat_messages (storing sender, content, and token counts). Connect the application to a Neon PostgreSQL instance via environment variables. Ensure strict TypeScript types across all database queries and include an initial migration script.02Chat-to-Code Agent Orchestration Loop
Implement the core AI agent loop using the Vercel AI SDK to stream natural language instructions into multi-file code generation updates.
Implement an AI code generation engine using the Vercel AI SDK (ai-sdk) configured with Anthropic Claude Sonnet. Create an API route /api/projects/[id]/generate that accepts a user prompt, retrieves the project's current virtual file tree from the Neon database, and uses streaming tool calls to modify, create, or delete files. The agent must return structured file patches that update the client-side virtual workspace. Implement strict system prompts ensuring the output adheres to a valid React, TypeScript, and Tailwind CSS component structure.03Live Preview and Sandboxed Execution
Build an isolated iframe-based live preview canvas that compiles and renders the generated React code dynamically.
Build a split-screen workspace UI in Next.js featuring a chat sidebar on the left and a live preview canvas on the right. Implement a client-side transpilation and bundling layer using secure sandboxed iframes or a web-based bundling mechanism so users can interact with their generated React application in real time as the agent updates files. Include a toggle to view raw code files with syntax highlighting.04Targeted Element Inspection and Selection
Add a visual selector tool that allows users to click elements on the preview canvas to inject precise context into the chat agent.
Develop a visual element-selector mode for the preview canvas. When enabled, hovering over elements in the iframe highlights them with bounding boxes, and clicking an element extracts its DOM path, component source file location, and outer HTML. Pass this structural context automatically into the chat input box so users can give targeted edit instructions like 'Change this button color to blue'.05Automated Error Fixing and Security Scans
Implement automated error-catching loops and a basic security scanner that runs checks on generated project configurations.
Implement an automated error-recovery subsystem. When a generated React project encounters a runtime or compilation error in the preview iframe, capture the stack trace via window.onerror and automatically send a background prompt back to the coding agent to fix the broken file without consuming user chat credits. Additionally, create a basic security scanner route that inspects generated database schemas for missing row-level security (RLS) policies and flags exposed secrets.06Deployment and GitHub Export
Add one-click deployment controls and GitHub repository synchronization for exporting generated codebases.
Build a deployment and export module. Integrate the GitHub REST API to allow users to sync their virtual project files directly into a new public or private GitHub repository with a single click. Implement a simulated publishing endpoint that bundles the static assets and deploys a snapshot URL under a custom subdomain configured in the database.
