What Is Vibe Coding?
A Plain-English Explanation
Vibe coding lets you build real, working software by describing what you want in plain language. No syntax. No development environment. No prior programming knowledge required. Andrej Karpathy coined the term in February 2025. Collins Dictionary named it Word of the Year 2025. Here is what it actually means — and what it does not.
Talk to an ExpertWhat vibe coding actually is
Vibe coding is the practice of building software by writing prompts in plain language — describing what you want to an AI, which then writes the underlying code. You say: 'Build a sign-up page with Google login and a user dashboard.' The AI generates working code. You iterate until it matches your vision. The term was coined by Andrej Karpathy — former Tesla AI director and OpenAI co-founder — in a post published in February 2025. He described building small personal tools entirely through natural language conversation with an AI, barely looking at the code itself. Collins Dictionary named 'vibe coding' its Word of the Year 2025, marking the moment a technical practice entered mainstream awareness.

Why it matters if you are not a developer
For decades, software was gated behind a two-to-three year learning curve or a £40,000-plus development budget. Vibe coding removes that gate. Founders, marketers, product managers, and designers can now build and ship working software without writing a single line of code themselves. The business implications are significant. A founder who can prototype and test in days rather than months reduces risk, preserves capital, and reaches early users before competitors have even finished scoping their builds. Y Combinator's Winter 2025 cohort reported that 25% of accepted startups had codebases that were 95% or more AI-generated. The shift is real — and it is accelerating.

How to start vibe coding
Starting is simpler than most people expect. The biggest early mistake is assuming you need to understand the generated code. You do not — at least not at first. Here is the process:
Step 1 — Pick a tool: Lovable or Bolt for full apps; v0 by Vercel for UI components
Step 2 — Describe your product: Write one paragraph covering what it does, who uses it, and what it looks like
Step 3 — Iterate with prompts: Each response is a first draft. Be specific about what to change
Step 4 — Connect your backend: Supabase for data, Stripe for payments, Vercel for hosting
Step 5 — Deploy: Push live in one click
Step 6 — Test with real users: Share a link and observe — do not guess
Step 7 — Refine: Use what you learn to write better prompts and improve the product
Real examples of vibe-coded products
The strongest evidence for vibe coding is products already in market — not demos or experiments, but tools that real users pay for and return to daily.

Common vibe coding mistakes
Vibe coding has a deceptively low floor — the first results feel immediate and satisfying. That ease creates a specific set of mistakes that non-developers consistently make when they push past simple prototypes.
Treating the first output as production-ready without any review
Adding too many features in one prompt instead of building incrementally
Skipping data security — AI tools do not add authentication or row-level security by default
Publishing without testing error states or edge cases
Assuming all vibe-coded apps will scale — most require infrastructure work before they can
How to vibe code well
The difference between a prototype that impresses in a demo and a product that works under real conditions is discipline in the prompting process. The best non-technical builders treat vibe coding the way senior engineers treat code review: structured thinking, clear constraints, and relentless testing before shipping anything to real users.
Write prompts that include user, action, and expected outcome — not just feature names
Build one feature at a time. Do not add more until the current feature works correctly
Add Supabase Row Level Security from the start — never as an afterthought
Test with five real users before adding any new functionality
