I've been coding for over a decade. Last month, I built a complete SaaS MVP in 3 days.
Not because I suddenly became 10x faster at typing. Because I barely typed any code at all.
Welcome to vibe coding — and it's changing everything.
## What is Vibe Coding?
The term was coined by Andrej Karpathy (yes, the Tesla AI guy) in early 2025:
"It's not really coding — I just see stuff, say stuff, run stuff, and copy-paste stuff, and it mostly works."
Instead of writing code line-by-line, you:
- Describe what you want in plain English
- Let AI generate the code
- Run it and see what happens
- Paste errors back to AI to fix
That's it. That's the whole workflow.
## Why Should You Care?
According to JetBrains' 2025 developer survey:
- 85% of developers now use AI tools regularly
- 62% rely on at least one AI coding assistant
- Developers save 1-8+ hours per week
This isn't a fad. This is the new normal.
## Free Tools to Start Vibe Coding Today (No Credit Card Needed)
You don't need to spend a dime to get started. Here are completely free options:
| Tool | What It Does | Why It's Great |
|------|--------------|----------------|
| Cursor | AI-powered IDE | Free tier with 2000 completions/month |
| Codeium | Code autocomplete | 100% free, unlimited, no catch |
| Continue.dev | Open source AI assistant | Free forever, works with VS Code |
| Aider | Terminal AI pair programmer | Free & open source |
| Claude.ai | Chat-based coding help | Free tier available |
| ChatGPT | General AI coding | Free tier available |
| GitHub Copilot | Inline suggestions | Free for students & open source maintainers |
My recommendation for beginners: Start with Codeium (unlimited free) + Claude.ai (for complex questions). Zero cost, full power.
## Paid Tools (When You're Ready)
Once you're comfortable, these are worth the investment:
| Tool | Cost | Best For |
|------|------|----------|
| Cursor Pro | $20/mo | Full IDE experience |
| GitHub Copilot | $10/mo | Inline completions |
| Claude Pro | $20/mo | Complex reasoning |
But seriously, the free tools are incredibly capable. I used only free tools for my first 6 months of vibe coding.
## Real Example: Building a URL Shortener in 10 Minutes
Here's exactly what I typed into Claude (free tier):
Create a FastAPI URL shortener with:
- POST /shorten - accepts URL, returns short code
- GET /{code} - redirects to original URL
- SQLite storage
- Rate limiting (10 req/min per IP)
What AI generated (working code):
from fastapi import FastAPI, HTTPException, Request
from fastapi.responses import RedirectResponse
from slowapi import Limiter
from slowapi.util import get_remote_address
import sqlite3
import string
import random
app = FastAPI()
limiter = Limiter(key_func=get_remote_address)
def init_db():
conn = sqlite3.connect("urls.db")
conn.execute("""
CREATE TABLE IF NOT EXISTS urls (
code TEXT PRIMARY KEY,
url TEXT NOT NULL
)
""")
return conn
@app.post("/shorten")
@limiter.limit("10/minute")
async def shorten(request: Request, url: str):
conn = init_db()
code = ''.join(random.choices(string.ascii_letters, k=6))
conn.execute("INSERT INTO urls VALUES (?, ?)", (code, url))
conn.commit()
return {"short_url": f"http://localhost:8000/{code}"}
@app.get("/{code}")
async def redirect(code: str):
conn = init_db()
result = conn.execute(
"SELECT url FROM urls WHERE code = ?", (code,)
).fetchone()
if not result:
raise HTTPException(404, "Not found")
return RedirectResponse(result[0])
Ran it. Worked first try. 10 minutes including testing. Cost: $0
The Prompting Secret Nobody Talks About
Bad prompt:
make a todo app
Good prompt:
Create a React TypeScript todo app with:
- Add/delete/toggle todos
- LocalStorage persistence
- Filter: all, active, completed
- Tailwind CSS styling
- Responsive design
The difference? Specificity.
The more constraints you give, the better the output. Think of it like giving directions — "go somewhere nice" vs "go to the Italian restaurant on 5th street."
When Vibe Coding Fails
Let's be real. It's not magic. It struggles with:
- Complex algorithms — AI often produces O(n²) when O(n) exists
- Security-critical code — Always review auth/crypto manually
- Large codebase refactors — Context window limits hurt
- Highly custom business logic — It doesn't know YOUR domain
I still write code manually for ~30% of my work. But that 70% automation? Game changer.
How to Start Today (5-Minute Setup)
Option A: Browser Only (Easiest)
- Go to https://claude.ai or https://chat.openai.com
- Describe what you want to build
- Copy the code, run locally
Option B: IDE Integration (Better)
- Install https://code.visualstudio.com
- Add https://codeium.com (free)
- Start typing — AI suggests completions
Option C: Full Vibe Coding Setup (Best)
- Install https://cursor.sh (free tier)
- Open any project
- Press Cmd+K / Ctrl+K
- Type what you want in English
- Hit enter and watch
Start with small tasks:
- "Add a loading spinner to this button"
- "Convert this function to async/await"
- "Write tests for this module"
Build confidence, then go bigger.
The Future is Conversational
In 5 years, I believe:
- Junior dev interviews will test prompting skills
- "Vibe coder" will be a real job title
- Writing code manually will feel like writing assembly
The developers who adapt now will have a massive advantage.
