What Is Vibe Coding

Vibe coding is building software by describing what you want in plain language and letting an AI write the code. Instead of typing every line yourself, you "talk" to the AI — "add a login screen," "make the header sticky," "save this to a database" — and it generates and edits the code for you. The term was coined by AI researcher Andrej Karpathy in February 2025, and it's reshaped how a lot of people (including non-developers) build apps.

We build software this way ourselves. Leo used an AI-assisted workflow to ship TipTillDone — a tip-management app for hospitality teams — in 22 days. So this guide is the honest version: what vibe coding actually is, the tools, who it's for, and the part most hype articles skip — where it breaks down, and what you do about it.

Where the term came from

Karpathy described "vibe coding" as a style where you "fully give in to the vibes, embrace exponentials, and forget that the code even exists." You describe intent, the AI writes it, you run it, and when something's off you just ask the AI to fix it — often without reading the code at all. For small, throwaway projects, that's genuinely how it feels now.

The key shift: the bottleneck moved from "can you write the code?" to "can you clearly describe what you want?" That's why people with no programming background are suddenly shipping working apps.

The two kinds of vibe-coding tools

"Vibe coding" actually splits into two different buyer types with different tools.

1. AI app builders (for non-technical builders)

These let you build a working web app by chatting — they handle the hosting, database and deployment for you. You describe the app, watch it appear in a live preview, and refine it in conversation. Popular options include Lovable, Bolt.new, Replit, v0, and Mocha. Best for founders, marketers and side-project builders who want a product, not a codebase to maintain.

2. AI code editors (for developers)

These bring AI into a real coding environment for people who already write (or want to learn) code. They autocomplete, refactor, and let you describe changes in natural language while keeping you in control of the actual files. Popular options include Cursor, Windsurf, GitHub Copilot, and Antigravity. Best when you want speed and the ability to understand and own what's shipped.

Who vibe coding is for

• Aspiring founders with an idea but no technical co-founder — you can now validate and even launch without one.
• Marketers and operators who want internal tools, landing pages or small SaaS without waiting on a dev team.
• Developers who want to compress timelines and offload boilerplate.

It is not a magic button. Which brings us to the honest part.

The honest limits — "vibe coding" vs shipping a real product

Here's what the hype leaves out: vibe coding is brilliant for getting to a prototype, and unreliable for getting to a product. The further you go, the more the "just let the AI handle it" approach starts to crack — auth edge cases, data integrity, payments, security, performance, and the dreaded moment where the AI confidently rewrites something that was already working.

The fix isn't to stop using AI. It's to use it with discipline. The method we used to ship TipTillDone wasn't "vibes" — it was spec-driven: write a clear spec first, let the AI build against it in small, reviewable steps, and keep a human in the loop for the decisions that matter (data model, auth, money, security). You get the speed of AI without the fragility.

That distinction — prototype fast with vibes, ship reliably with a spec — is the single most useful thing to internalize before you start.

How to start vibe coding (a realistic first day)

1. Pick one small, real idea. Not "the next big SaaS" — something you'd actually use this week.
2. Choose your tool type. Non-technical? Start with an AI app builder. Comfortable with code? Use an AI code editor.
3. Write a one-page spec first. What it does, who it's for, the 3–5 core screens, and the data it stores. This single habit is what separates a demo from a product.
4. Build in small steps. Ask for one feature at a time, run it, confirm it works, then move on. Commit often so you can roll back.
5. Review the risky parts yourself. Anything touching login, payments, or user data — read it, or have it explained, before you ship.
6. Deploy early. Getting it live (even rough) beats polishing forever in a preview window.

Frequently Asked Questions

What is vibe coding in simple terms?

Vibe coding is making software by telling an AI what you want in plain English and letting it write the code, instead of programming every line yourself. The phrase was coined by Andrej Karpathy in early 2025.

Do you need to know how to code to vibe code?

No — that's the point. AI app builders like Lovable, Bolt and Replit let non-developers build working apps by describing them. You'll ship faster and more reliably, though, if you understand the basics of what you're building (especially around data, login and payments).

Is vibe coding good enough to build a real product?

For prototypes and small tools, absolutely. For a real, paying product, pure "vibes" tends to break down — you need a disciplined, spec-driven approach to handle auth, data, payments and security. We built TipTillDone that way in 22 days.

What's the difference between AI app builders and AI code editors?

App builders (Lovable, Bolt, Replit, v0) build and host a whole app from a conversation — best for non-developers. Code editors (Cursor, Windsurf, Copilot) bring AI into a real coding setup — best for developers who want speed while keeping control.

How do I start vibe coding today?

Pick one small idea, write a one-page spec, choose an AI app builder (non-technical) or an AI code editor (technical), and build one feature at a time. See the step-by-step in our guide to building an app with AI.
