- Vibe coding means describing what you want in plain language and letting AI write the code.
- It is great for prototypes, personal tools and learning, but risky for anything that handles money or private data.
- Always test, review and secure AI-written code before real users depend on it.
The Short Answer
Vibe coding is a way of building software where you describe what you want in everyday language and an AI tool writes the code for you. The term was popularised by AI researcher Andrej Karpathy in early 2025. You steer by giving instructions, running the result and asking for changes, rather than typing every line yourself. It can turn an idea into a working prototype in an afternoon, but the code can hide bugs and security holes that you may not notice if you do not read it.
How Vibe Coding Works
You open an AI coding tool, describe the app (for example, a booking page for a barber shop), and the tool generates files, runs them and shows you the result. You then reply with changes such as 'make the button bigger' or 'add a phone number field'. The loop repeats until it looks right. Popular tools include AI code editors, terminal agents and web-based app builders. See our comparison of AI coding agents for the main options.
What It Is Good For
- Prototypes: show an idea to a client or investor quickly.
- Personal tools: a budget tracker, a quiz, a simple calculator.
- Learning: read the code the AI writes and ask it to explain each part.
- Small websites and automations: where a mistake costs little.
Where It Goes Wrong
| Risk | What can happen |
|---|---|
| Hidden bugs | The app works in the demo but breaks with real data or many users |
| Security holes | Passwords, API keys or customer data exposed by careless code |
| Code you cannot maintain | When something breaks, nobody understands how it works |
| Made-up details | The AI invents a library or feature that does not exist |
None of these risks means you should avoid the approach. They mean you should treat AI output as a first draft, not a finished product.
A Safe Vibe Coding Routine
- Start with a clear, small goal and write it down in one paragraph.
- Ask the AI to explain its plan before it writes code.
- Build in small steps and test after each one.
- Never paste passwords, API keys or customer data into a prompt.
- Before launch, follow our guide to reviewing and testing AI-written code.
When to Bring in a Developer
If the app takes payments, stores personal information, or your business depends on it, have an experienced developer review it. Vibe coding lowers the cost of building, but it does not remove the responsibility for safety. Good prompts also help a lot, so read our guide on writing better prompts for coding with AI.
Action Checklist
- Describe the goal in one clear paragraph
- Ask for a plan before code
- Build and test in small steps
- Keep secrets out of prompts
- Review security before real users arrive
- Use a developer for payments or private data
