What is Vibe Coding? Complete Guide to AI-First Development (2026)
From a viral tweet by Andrej Karpathy to a $4.7 billion industry. Learn what vibe coding is, how it works, the best tools to get started, and why 92% of US developers now use AI coding tools daily.
What is Vibe Coding?
Vibe coding is an AI-assisted software development practice where developers describe high-level functional intent to large language models (LLMs), which then generate executable code. Instead of writing code line by line, you describe what you want in plain language, and AI builds it for you.
The term was coined by Andrej Karpathy — former AI director at Tesla and co-founder of OpenAI — on February 2, 2025, in a viral X (Twitter) post that accumulated over 4.5 million views.
“There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
— Andrej Karpathy, February 2, 2025
The concept struck a nerve. Within months, “vibe coding” was named Collins Dictionary Word of the Year 2025, Merriam-Webster added it as a slang term in March 2025, and search interest for the term increased 6,700% throughout the year.

How Vibe Coding Works: The 5-Step Workflow
Vibe coding follows a simple, iterative loop. You describe, the AI generates, you review and refine until it's right.
Describe What You Want
Write a natural language prompt describing the feature, component, or full application you want to build. Be specific about functionality, but let the AI handle implementation details.
AI Generates Code
The LLM interprets your intent, selects appropriate libraries and patterns, and generates working code — often across multiple files including frontend, backend, and database schemas.
Test and Iterate
Run the code, test the output, and provide feedback. If something isn't right, describe the changes you need. The AI adjusts incrementally while maintaining context of previous decisions.
Review and Refine
Examine the generated code for correctness, security, and maintainability. Use the AI to explain unfamiliar patterns. Flag any hardcoded secrets, missing validations, or insecure patterns.
Deploy
Once satisfied, deploy the application. Use CI/CD pipelines, automated testing, and monitoring. Vibe coding doesn't end at code generation — production-readiness still requires human oversight.
Key insight: Vibe coding is iterative, not one-shot. The best results come from breaking complex tasks into small, well-defined prompts and reviewing after each step.

Vibe Coding vs Traditional Coding
A side-by-side comparison to understand where vibe coding excels and where traditional approaches still win.
The reality: Most professional developers use a hybrid approach — vibe coding for speed on boilerplate and scaffolding, traditional coding for performance-critical and security-sensitive logic.
Getting Started: Your First Vibe-Coded App
Ready to try vibe coding? Here's a step-by-step guide to building your first app from scratch with AI.
Step 1: Choose Your Tool
Pick a vibe coding platform. For beginners, Bolt.new or Lovable require zero setup. For developers, install Cursor and connect it to your project.
Tip: Start with a free tier — every tool listed above has one.
Step 2: Define Your App Clearly
Write a 2-3 sentence description of what your app does, who it's for, and the core feature. Example: "A task management app for freelancers that tracks projects, time spent, and generates invoices."
Tip: The clearer your initial prompt, the better the AI output.
Step 3: Create a Wireframe
Sketch the main screens — even on paper. This helps you describe layout and flow to the AI. Tools like Figma, Penpot (free), or even a whiteboard photo work great.
Tip: Some tools like v0 and Lovable accept image inputs as design references.
Step 4: Prompt in Incremental Steps
Don't ask for the whole app at once. Start with: "Create a Next.js app with a landing page." Then: "Add a sign-up form with email and password." Build feature by feature.
Tip: Treat AI prompts like git commits — small, focused, reviewable.
Step 5: Review After Each Iteration
After each AI-generated change, review the code. Check for hardcoded values, missing error handling, and security issues. Ask the AI to explain anything you don't understand.
Tip: Use "Explain this code" prompts liberally. Understanding what was generated is critical.
Step 6: Add Data & Auth
Use Supabase (free tier) for your database and auth. Prompt the AI: "Add Supabase authentication with Google OAuth and a users table with RLS policies."
Tip: Always enable Row Level Security. Prompt the AI to set it up for you.
Step 7: Deploy
Deploy to Vercel (free) with one command. Connect your GitHub repo and every push auto-deploys. Add environment variables for API keys.
Tip: Never hardcode API keys. Always use .env files.
Best Practices & Prompt Engineering
Vibe coding is only as good as your prompts and process. Follow these practices to get the most out of AI-first development.
Prompting Tips
- Define clear intent before prompting — know what you want
- Prompt in incremental steps, not all at once
- Include context: tech stack, file structure, constraints
- Use rules files (.cursorrules) for project consistency
- Ask AI to explain generated code before accepting it
- Follow the Research-Plan-Implement framework
Process Tips
- Create wireframes to guide AI output
- Structure data models and user roles upfront
- Review changes after each iteration — don't batch
- Use version control (git) religiously
- Test edge cases the AI might miss
- Human review is non-negotiable for production
Example Prompt Structure
# Context I'm building a SaaS task manager with Next.js 15, Supabase, and Tailwind CSS. Using App Router. # Current State I have auth working with Supabase. The database has a "projects" table with RLS enabled. # Request Add a dashboard page that shows all projects for the logged-in user. Include a "New Project" button that opens a modal with a form (name, description, due date). Use Server Components for data fetching and a Server Action for the form submission. # Constraints - Follow existing code patterns in /src/components - Use shadcn/ui components - Validate with Zod
Security Considerations
The Uncomfortable Truth
Studies show 45-62% of AI-generated code contains security flaws. Meanwhile, 40% of junior developers deploy AI code they don't fully understand. 75% of R&D leaders express concern about data privacy and security with vibe coding tools.
Security Checklist for Vibe Coders
Never hardcode API keys
Always use .env files and server-side environment variables. Prompt AI to use process.env.
Enable database security
Use Row Level Security (RLS), auth policies, and parameterized queries. Never trust client-side data.
Sanitize all user input
Prevent SQL injection, XSS, and CSRF attacks. Validate inputs on the server side, not just the client.
Set secure HTTP headers
Add Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security headers.
Review auth flows carefully
AI often generates auth code that looks correct but has subtle flaws. Double-check token handling and session management.
Validate inputs server-side
Client-side validation is for UX, server-side validation is for security. AI sometimes skips the latter.
Use dependency scanning
AI may suggest outdated or vulnerable packages. Run npm audit and use tools like Snyk or Socket.
Human review is mandatory
Before deploying anything to production, a human must review security-critical code paths.
Who's Using Vibe Coding?
From Y Combinator startups to Fortune 500 companies, vibe coding is everywhere.
Y Combinator Startups
25% of Y Combinator's Winter 2025 batch runs codebases that are 95% AI-generated. Vibe coding has become the default for early-stage startups where speed to market is everything.

Limitations & When NOT to Vibe Code
Vibe coding is powerful, but it's not a silver bullet. Here's an honest assessment of where it falls short.
Safety-critical systems
Medical devices, aviation software, financial trading engines — anywhere bugs can cause real harm. These require formal verification and rigorous testing that AI alone can't guarantee.
Performance-critical code
Low-level systems programming, real-time applications, and high-frequency trading. AI-generated code is often correct but not optimal for performance-sensitive paths.
Novel algorithms
LLMs generate code based on patterns they've seen. Truly novel algorithms or research-grade implementations still require human expertise and deep domain knowledge.
Large legacy codebases
While AI can help with refactoring, navigating large, poorly-documented legacy systems with complex business logic remains challenging for current tools.
Compliance-heavy domains
HIPAA, SOC 2, PCI DSS compliance requires understanding exactly what your code does. Blindly accepting AI-generated code in regulated industries is risky.
Known Risks
- 45-62% of AI code contains security flaws
- 40% of juniors deploy code they don't understand
- Weaker comprehension without code review discipline
- 17.5% of developers opting out entirely
Mitigations
- Always review generated code before deploying
- Use automated security scanning (Snyk, npm audit)
- Write tests for critical business logic
- Invest in understanding the code AI generates
The Future of Vibe Coding
The $4.7 billion market is projected to reach $12.3 billion by 2027. Here's where vibe coding is headed.
Agentic AI becomes the norm
AI tools are evolving from code completion to autonomous agents that can plan, execute, test, and deploy entire features. Claude Code and Cursor's agent mode are early examples.
AI-native IDEs replace traditional ones
IDEs built around AI from the ground up (Cursor, Windsurf) are outpacing VS Code extensions. Expect the IDE to become more of a conversation interface than a text editor.
Democratization accelerates
As AI coding improves, the barrier to building software continues to drop. The 63% non-developer user base will keep growing, creating new categories of "citizen developers."
Security tooling catches up
AI-specific security scanning, automatic vulnerability detection in generated code, and compliance-aware code generation are emerging rapidly to address the 45-62% vulnerability gap.
Hybrid workflows solidify
The future isn't pure vibe coding or pure traditional coding — it's a spectrum. Developers will fluidly switch between natural language and manual coding depending on the task.
Market trajectory: The global vibe coding platform market is valued at $4.7 billion in 2026 and projected to reach $12.3 billion by 2027 — a 161% increase. With 256 billion lines of AI-generated code in 2024 alone, the volume of AI-written software is growing exponentially.
