Vibe coding has revolutionized software development by enabling anyone to build functional applications through natural language conversations with AI assistants, rather than writing code line-by-line. Coined by AI researcher Andrej Karpathy in early 2025, this approach shifts developers from implementation details to high-level vision, while AI handles the actual code generation. The result? Complete applications built in hours instead of weeks, accessible to both experienced developers and beginners alike.
Understanding Vibe Coding
Vibe coding operates on two distinct levels: the low-level iterative loop where you refine specific code segments through conversational prompts, and the high-level lifecycle that takes your concept from idea to deployed application. Unlike traditional programming where you manually write commands and syntax, vibe coding lets you describe desired outcomes in plain language—like "create a user login form"—while AI generates the implementation.
The practice excels at rapid prototyping, handling boilerplate code, and helping you explore multiple approaches quickly. For first-time app founders with limited technical experience, vibe coding can be transformative, enabling working prototypes that validate ideas and even ship to early users.
Essential Free Tools for Vibe Coding
Core Development Platforms
Cursor AI stands as the premier AI-powered code editor for vibe coding, built like VS Code but enhanced with GPT-4 integration. You can highlight code sections and ask questions like "Refactor this into hooks" or request explanations, making it ideal for the complete development lifecycle. Cursor's AI chat panel generates and refines code while providing context-aware debugging tools.
Replit Agent offers a browser-based alternative that scaffolds entire projects, sets up environments automatically, and generates initial code without manual configuration. The platform creates visual previews, manages Git checkpoints, and provides seamless publishing—all within the browser.
Lovable represents the most balanced option for beginners, generating smooth designs with good functionality from the start. It sketches implementation plans before writing code and explains its actions, providing a strong sense of control. The platform integrates with Supabase for backend services and GitHub for version control.
Supporting Technologies
Node.js serves as your JavaScript runtime environment, essential for running applications locally. Git provides version control, creating checkpoints throughout development so you can revert if AI makes unwanted changes. Claude Desktop or Claude Code can assist with initial project generation and documentation creation.
Step-by-Step Development Process
Phase 1: Planning and Setup
Begin by conceptualizing your application with a clear vision of the desired outcome. Domain knowledge significantly improves AI-generated results—knowing relevant frameworks or data sources helps guide the AI more effectively.
Create comprehensive documentation outlining features, user flows, and technical requirements. Tools like VibeCodeDocs.dev generate tailored documentation through AI-assisted questionnaires, keeping your development on track and preventing AI hallucinations or feature creep. The platform offers one free project for new users.
Choose your technology stack based on popularity and AI training data. For web applications, React with Tailwind CSS and Shadcn UI handles the frontend, while Next.js manages the backend. Supabase provides database functionality and authentication. These technologies represent the most common stack, ensuring optimal AI performance.
Phase 2: Initial Code Generation
Using Cursor AI:
Install Cursor from cursor.com and create a new project folder. Open the AI chat panel and provide your comprehensive project documentation. Use specific prompts like "Create this web app using React, Next.js, and Supabase. Put API keys in .env.local file. Use the most recent package versions."
Configure project rules in Cursor settings to keep the AI aligned with your documentation throughout development. Reference your documentation file using the @ symbol so the agent always maintains context.
Using Replit Agent:
Craft an initial prompt that specifies your goal, key technologies, and specific requirements. Attach mockups or sketches to help Agent understand your desired layout. Agent will create a plan for review, stream a visual preview, configure the environment automatically, and write both frontend and backend code.
Phase 3: The Development Loop
The core development process follows an iterative cycle: identify issues, provide feedback to AI, review generated code, test functionality, and commit successful changes.
Debugging Techniques:
When errors occur, copy error messages from your console and paste them directly into the AI chat with context about what you were trying to accomplish. Use browser DevTools—specifically Console and Network tabs—to identify specific failures. For visual issues, take screenshots and attach them to your prompts, allowing AI to perform image analysis.
Making Refinements:
Switch to more targeted assistants like Replit Assistant for smaller edits once your MVP is functional. These specialized tools work faster for focused changes like styling improvements, adding dark mode, or adjusting specific components.
Provide explicit, detailed feedback when AI makes incorrect assumptions. Instead of "fix the button," specify "The submit button has white text on a light background making it barely visible. Change the button background to a darker shade while keeping the white text."
Phase 4: Database and Backend Setup
Supabase Configuration:
Create a free account at supabase.com and establish a new project. Generate a strong database password and select your nearest region for optimal performance. Copy your project URL, anon key, and service role key into your application's .env.local file.
Database Schema:
Request your AI assistant to generate all necessary SQL code for your database tables. Copy the provided SQL statements and paste them into Supabase's SQL Editor, then execute to create your schema. This approach ensures your database structure matches your application requirements without manual table creation.
Testing Authentication:
Supabase handles user authentication automatically once configured. Test signup and login flows thoroughly, checking for proper session management and data persistence.
Phase 5: Version Control with Git
Initialize a Git repository in your project folder to create restore points throughout development. In Cursor, click the version control icon and select "Initialize Repository."
After completing each feature or fixing significant issues, stage all changes and create commits with descriptive messages. Use Git's commit functionality as checkpoints—if AI drastically changes your codebase incorrectly, you can revert to previous stable versions.
Create a GitHub account and publish your repository as either public or private. This remote backup protects your code and serves as the foundation for deployment.
Deployment and Publishing
Web Application Deployment with Vercel
Vercel provides zero-configuration deployment for React and Next.js applications with built-in CI/CD. The platform automatically assigns a .vercel.app domain while supporting custom domains.
Deployment Methods:
Git Integration (Recommended): Connect your GitHub repository to Vercel through the dashboard. Each commit automatically triggers a new deployment, with pull requests receiving unique preview URLs. Vercel detects your framework and applies correct settings automatically.
Vercel CLI: Install the CLI with npm i -g vercel, navigate to your project directory, and run vercel --prod. This creates a production deployment and links your local directory to your Vercel project.

Best Practices and Common Pitfalls
Optimization Strategies
Create detailed documentation before generating code to prevent structural issues and AI hallucinations. Break complex features into smaller, manageable prompts rather than requesting everything at once. Test frequently throughout development rather than waiting until the end.
Maintain clear project rules in your AI editor settings, referencing your documentation file to keep the assistant aligned with your vision. Use descriptive Git commit messages to track your development progress effectively.
Security Considerations
Store all API keys and secrets in environment variables (.env.local files) rather than hardcoding them. Never commit sensitive credentials to public repositories. Review AI-generated code for potential security vulnerabilities, particularly in authentication and data handling logic.
Run npm audit regularly to identify and fix package vulnerabilities in your dependencies.
