Vibe coding: what it is, what you can build, and how to start
Vibe coding means building software by describing what you want to an AI in plain language and letting it write the code. For a business owner it is a real opportunity: a working prototype in an evening, a small internal tool in a weekend. It also has a well-known way of going wrong. Here is how to get the first without the second.
What vibe coding actually is
The term was coined by Andrej Karpathy in early 2025 for a way of working where you describe a feature, the AI writes it, you look at the result and ask for changes, often without reading the code at all. The tools range from browser-based app builders such as Lovable, Bolt, Replit and v0 to coding assistants that work inside a project on your own computer, such as Claude Code.
What changed is who can build. You no longer need to write code to get working software. You still need to know what the software should do, and that is the part business owners are best at.
What it is good for
- Prototypes that test an idea with real people before you spend real money on it.
- Landing pages and simple websites.
- Internal tools for a few people you trust: calculators, dashboards, checklists.
- Automating your own routine: a script that builds a report or tidies a spreadsheet.
- Learning how software works by building something you actually need.
Where it breaks
- User accounts, roles and who may see what.
- Payments, and anything else that must be exactly right.
- Personal data of customers.
- Many users at once.
- Months of changes stacked on changes, until nobody understands the code and every fix breaks something else.
None of these shows up in a demo. They show up when real people use the product, which is why so many vibe-coded apps feel finished and are not. The answer is not to avoid vibe coding. It is to know which parts need a designed foundation.
How to start, step by step
Write down what it must do
One paragraph: who uses it, the three things it must do, and what data it keeps. This brief is worth more than any prompt trick.
Pick the right kind of tool
A browser builder if you want a quick prototype; a coding assistant if you plan to keep the product and change it for years. The comparison below goes through the options.
Start with the smallest useful version
One screen, one flow. Add features one at a time, and test each one before asking for the next.
Keep everything in your own accounts
Code in your own GitHub, hosting and domain in your name, so you can move the project later instead of being stuck on a platform.
Check before you share it
Before real users or real data arrive, go through the security checklist. Most problems are a handful of missing basics.
Change in small steps
One change per request, checked before the next, with a working version you can always go back to.
When it is worth getting help
- The prototype works, and real users or customers are about to arrive.
- The product handles payments, accounts or personal data.
- Every fix breaks something else, and you spend more on credits than you gain in progress.
That is the moment for a proper foundation under what you built, and for learning to keep building on it safely. You keep the idea, the design and the habit of building with AI.
Frequently asked questions
Do I need to know how to code?
Not for a prototype. As the project grows, a basic picture of how software is put together — what a database is, what runs in the browser and what on the server — helps a lot, and you pick it up as you build.
Is vibe coding safe for a real business?
For prototypes and internal tools, usually yes, with some care. For anything with customer accounts, payments or personal data, the foundation needs to be designed by someone who knows how — that is the part AI builders skip.
Which tool should I start with?
It depends on whether you want a quick demo or a product you will keep. Our comparison of Lovable, Bolt, Replit, v0 and Claude Code goes through it.
Can a vibe-coded prototype become the real product?
It is an excellent blueprint: it shows exactly what the product should do. When a prototype has outgrown its foundation, we rebuild it rather than patch it, keeping the design and flows.
How much does it cost?
The tools charge monthly subscriptions and usage credits, so check their current prices. The hidden cost is the time and credits spent in loops of fixes that break something else.
