Vibe coding means building software by describing what you want to an AI in plain language and letting it write the code, instead of writing the code yourself. You test the result, tell the AI what to change and repeat. Beginners can build simple websites, tools and prototypes this way with apps such as Lovable, Bolt.new, Replit and Google AI Studio, while developers use AI coding assistants such as Cursor and Claude Code. It is fast and fun, but AI-written code can hide bugs and security problems, so it works best for prototypes and personal projects. This guide explains how it works, which tools to use and how to build your first app safely.
Where does the term “vibe coding” come from?
AI researcher Andrej Karpathy, a co-founder of OpenAI, coined the phrase in February 2025 to describe coding where you “fully give in to the vibes” and let the AI handle the details. The idea spread quickly, and Collins Dictionary named “vibe coding” its Word of the Year for 2025, describing it as using AI to tell a computer what you want instead of writing the code yourself.
How does vibe coding work?
- Describe the app. For example: “Build a simple tip calculator with a bill amount, a tip percentage slider and a split-between field.”
- The AI writes the code and usually shows a live preview right away.
- You test it like a normal user: click everything, try odd inputs, check it on your phone.
- You ask for changes in plain language: “Make the buttons bigger” or “Round the result to two decimals.”
- You repeat until it works, then publish or download the project.
The skill shifts from typing code to describing clearly what you want and checking the result carefully.
Vibe coding vs AI-assisted programming
| Vibe coding | AI-assisted programming | |
|---|---|---|
| Who it suits | Beginners, designers, founders testing ideas | Developers working on real codebases |
| Reading the code | Rarely; you judge by the result | Always; the developer reviews every change |
| Typical tools | Lovable, Bolt.new, Replit, v0, Google AI Studio | Cursor, Claude Code, GitHub Copilot |
| Best for | Prototypes, personal tools, landing pages | Production apps that must be secure and maintained |
If you already code, compare the developer tools in GitHub Copilot vs Claude Code vs Cursor.
Which tools can you use for vibe coding?
- Lovable: builds full web apps from a chat, with a live preview and one-click publishing. Its free plan gives 5 build credits a day, up to 30 a month.
- Bolt.new: creates and runs web apps in the browser from a prompt, and lets you edit the generated files.
- Replit: an online coding platform whose AI agent can build, run and deploy apps, with a free starter plan.
- v0 by Vercel: strong at generating website interfaces and components from a description or a screenshot.
- Google AI Studio: its Build mode lets you describe an app and test it with Gemini, free with a Google account.
- Claude, ChatGPT and Gemini chat apps: fine for small single-page tools; ask for “one HTML file” and open it in your browser.
Free plans and limits change often, so check each tool’s pricing page before you start a big project. For more free options, see our list of the best free AI tools.
How do you build your first app with vibe coding?
- Pick a tiny project. A to-do list, a habit tracker or a calculator. Small projects teach you how the AI responds without getting lost.
- Write a clear first prompt. Say who it is for, what it should do, the main screens and the look. Example: “A mobile-friendly habit tracker for students. Users add habits, tick them off each day and see a weekly streak. Clean, light design with large buttons. Save data in the browser.”
- Change one thing at a time. Many small requests work better than one long list of changes.
- Test like a stranger. Empty fields, very long text, a phone screen, a slow connection.
- Describe bugs precisely. “When I add a habit with an empty name, the page goes blank” is much better than “it is broken”.
- Save working versions. Use the tool’s version history or export the project before big changes.
- Publish only when it is safe, using the checklist below.

What are the risks of vibe coding?
- Security holes: AI-generated apps can expose data, skip login checks or leave databases open. Never collect passwords, payments or personal data in an app you cannot review.
- Exposed API keys: if your app calls an AI or payment service, the secret key must stay on a server, never in the page code. Learn why in what is an API key.
- Hidden bugs: an app can look right and still calculate wrong. Check results by hand.
- Hard to maintain: after many rounds of changes, the code can become messy, and fixing one thing may break another.
- Costs: credits run out fast on big projects, and hosting or database add-ons may cost extra.
- Privacy: do not paste confidential company code or customer data into tools that may store it. Review your AI chatbot privacy settings.
Safety checklist before you publish
- Ask the AI: “Review this app for security problems and list anything that exposes data or keys.”
- Make sure no API keys or passwords appear in the front-end code.
- If users sign in, test that one user cannot see another user’s data.
- Use strong, unique passwords for your hosting and database accounts; our Password Generator can create them.
- For anything handling money or personal data, have a developer review it.
Is vibe coding good for learning to code?
It can be, if you stay curious. Ask the AI to explain each part of the code, change small things yourself and see what happens. Building something you care about is a strong motivator. But if you only copy and paste, you will not learn to fix problems on your own. Students can find more learning-friendly options in our list of the best AI tools for students.

Frequently asked questions
Can you build an app without knowing how to code?
Yes, for simple websites, personal tools and prototypes. For apps that handle payments, personal data or many users, you still need someone who can read and secure the code.
Is vibe coding free?
Most tools have free plans with daily or monthly limits. Small projects often fit in the free tier; bigger ones usually need a paid plan.
What is the best tool for vibe coding?
For complete beginners, Lovable, Bolt.new or Replit, because they handle hosting for you. If you can code, Cursor or Claude Code give you more control.
Will vibe coding replace programmers?
It changes the job more than it replaces it. AI writes more of the code, while people still decide what to build, check that it works and keep it secure.
Start small and stay safe
Pick a tiny idea, describe it clearly, test every change and keep secrets out of your code. When you are ready for more, explore our AI tools guide and our free online tools, many of which are small browser apps like the ones you can build this way.
