What is Vibe Coding? The AI Coding Revolution Explained

What is vibe coding?

Vibe coding is a new approach to software development where you describe what you want to build in natural language, and an AI generates the working code for you. The term was coined by Andrej Karpathy in early 2025, when he described it as “fully giving in to the vibes, embracing exponentials, and forgetting that the code even exists.”

Instead of writing code line by line, you have a conversation with an AI. You say “Create a dashboard with sales charts and a customer table,” and the AI generates a complete React application with interactive charts, styled components, and responsive layout. You see the result in real-time and refine it through further conversation.

In 2026, vibe coding has grown from an experimental concept to a mainstream development approach. With 92% of professional developers using AI coding tools daily, the line between “traditional” and “vibe” coding is blurring fast.

How vibe coding works

1. You describe, AI codes. You write a natural language description of what you want. The AI model (Claude, GPT, or others) interprets your intent and generates the corresponding code. The better your description, the better the output.

2. Real-time preview. Modern vibe coding platforms like Demeria show you the result as it's being generated. You watch your app take shape in a live preview, powered by browser-based sandboxes like Sandpack.

3. Iterative refinement. You refine through conversation: “Make the header sticky,” “Add a dark mode toggle,” “Change the chart colors to blue.” Each message updates the code and the preview. This back-and-forth is the core of vibe coding.

4. Deploy and share. When you're satisfied, deploy your app with one click. The generated code is standard React with TypeScript — it runs anywhere and can be further customized in any IDE.

Who is vibe coding for?

Entrepreneurs and founders. Validate your startup idea in hours instead of months. Build a working MVP, test it with real users, iterate based on feedback. No need to hire a development team for the initial prototype.

Developers who want to move faster. Skip the boilerplate. Use vibe coding for UI generation, prototyping, and standard CRUD interfaces. Focus your manual coding efforts on the parts that truly need human creativity and expertise.

Designers. Turn your designs into working code without waiting for a developer. Describe your vision, see it rendered live, and share an interactive prototype instead of static mockups.

Students. Learn how modern web apps are built by seeing the code the AI generates. It's like having a senior developer pair-programming with you, explaining every decision through working code.

Freelancers. Deliver client projects 5–10x faster. A landing page in 30 minutes, a multi-page site in 2 hours. The economics are transformative — learn more about creating apps with AI.

Best vibe coding tools in 2026

Demeria. AI app builder with multi-model support (Claude and GPT), subscription-based pricing with generous credit tiers, real-time Sandpack preview, and one-click deployment. Supports both French and English. Plans from €20/month with 5 free daily credits for everyone.

Lovable. Popular AI app builder focused on React generation. English-only interface, single AI model, $25/month for 100 credits. Free tier limited to public projects. Compare Demeria vs Lovable.

Bolt.new. StackBlitz-powered AI coding tool. Fast iteration with WebContainers technology. Token-based pricing from $20/month with daily limits. Compare Demeria vs Bolt.new.

v0 by Vercel. UI generation tool by the creators of Next.js. Excels at generating individual components and UI sections. Less suited for full applications compared to Demeria.

Cursor. AI-powered code editor. More developer-focused: requires some coding knowledge, works with your local files. Best for developers who want AI assistance within a traditional IDE workflow.

Getting started with vibe coding

The fastest way to try vibe coding is to sign up on Demeria and start a new project. You get free daily credits — no credit card required.

Start simple. Your first project should be something small: a personal portfolio, a landing page for a side project, a simple tool. This lets you learn the prompting style without overcomplicating things.

Be descriptive. The more context you give the AI, the better the result. Mention colors, layout preferences, specific features, the mood you want. Think of it as briefing a designer — the clearer the brief, the better the output.

Iterate, don't restart. If the first generation isn't perfect (it rarely is), refine through conversation. Ask for specific changes rather than regenerating from scratch. Vibe coding is an iterative dialogue, not a one-shot generation.

Learn from the code. Even if you're not a developer, glancing at the generated code teaches you patterns. Over time, you'll write better prompts because you understand what the AI is producing.

Limitations and when to use traditional coding

Vibe coding is powerful, but it's not the right tool for everything. Understanding its limitations helps you make better decisions about when to use it.

Complex backend logic. While vibe coding excels at frontend generation, complex server-side logic, database optimization, and system architecture still benefit from experienced developers. Tools like Demeria's Supabase integration bridge this gap for standard CRUD operations.

Performance-critical code. If you need micro-optimized algorithms, real-time systems, or highly concurrent applications, manual coding gives you the control needed for performance tuning.

Large existing codebases. Vibe coding works best for greenfield projects. Integrating AI-generated code into a large existing codebase requires developer knowledge to ensure consistency and avoid regressions.

That said, vibe coding handles the majority of web application needs: landing pages, portfolios, dashboards, admin panels, CRUD applications, and SaaS MVPs. For most people, it's the fastest path from idea to working product.
