Vibe Coding: The New Trend Dividing Developers in 2026

Hello HaWkers, if you follow the dev world on Twitter/X or LinkedIn, you've probably seen the term "Vibe Coding" appearing everywhere. The practice is generating heated debates among developers.

Let's understand what Vibe Coding is, why it exploded in popularity, and what the real risks are.

What Is Vibe Coding

Definition

Vibe Coding is a development approach where the programmer uses AI to generate code based on high-level descriptions, without necessarily understanding each line of the generated code.

Characteristics of Vibe Coding:

• Focus on describing "what" instead of "how"
• Rapid iteration with AI assistants
• Acceptance of code that "works" without deep analysis
• Prioritizing speed over understanding
• Debugging by trial and error with AI help

Practical example:

Vibe Coder's Prompt:
"Make an authentication system with JWT, refresh token,
and Google OAuth integration. Use Express and MongoDB."

AI generates ~500 lines of code

Vibe Coder: "Did it work? Ship it!"

How It Emerged

The term gained popularity in late 2025, initially coined as criticism but ironically adopted by practitioners.

Timeline:

1. 2023-2024: GitHub Copilot becomes popular
2. 2025: Claude, GPT-4 and others improve drastically in code
3. Late 2025: "Building apps in 10 minutes with AI" videos go viral
4. 2026: Term "Vibe Coding" becomes established

The Debate: Pros and Cons

Arguments in Favor

1. Democratization of development:

Before: Needs years of study to create an app
Now: Anyone can prototype ideas

"Vibe Coding allowed me, a designer, to create
my own portfolio app in a weekend"
- Reddit user

2. Multiplied productivity:

Task	Traditional	Vibe Coding
Basic CRUD	4 hours	30 min
Landing page	8 hours	1 hour
Simple REST API	1 day	2 hours
MVP prototype	2 weeks	2 days

3. Focus on business problems:

Traditional developer:
- 70% writing code
- 30% solving business problems

Vibe Coder:
- 30% guiding AI
- 70% solving business problems (theoretically)

4. Reduced barrier to entry:

• Entrepreneurs can validate ideas quickly
• Students can create more ambitious projects
• Non-tech areas can automate tasks

Arguments Against

1. Hidden technical debt:

// AI-generated code that "works"
// but has serious problems

app.get('/user/:id', async (req, res) => {
  // Vulnerable SQL Injection
  const query = `SELECT * FROM users WHERE id = ${req.params.id}`;

  // No proper error handling
  const user = await db.query(query);

  // Exposes sensitive data
  res.json(user);
});

// Vibe Coder: "It's working, let's move to the next"

2. Lack of understanding:

Common scenario:

1. AI generates code that works
2. Bug appears in production
3. Dev doesn't understand the code
4. Dev asks AI to fix
5. AI introduces new bug
6. Infinite loop of patches

Result: Fragmented, inconsistent, insecure code

3. Compromised security:

// Examples of common problems in Vibe Coding

// 1. Exposed secrets
const API_KEY = 'sk-live-xxxxx'; // AI puts directly in code

// 2. Nonexistent validation
app.post('/transfer', async (req, res) => {
  const { amount, toAccount } = req.body;
  // No validation, any value passes
  await transferMoney(amount, toAccount);
});

// 3. Missing rate limiting
// 4. Misconfigured CORS
// 5. SQL/NoSQL injection
// 6. XSS vulnerabilities

4. AI dependency:

Informal Twitter poll (2026):

"Could you write your last project without AI?"

Traditional devs: 89% yes
Vibe Coders: 23% yes

Concerning for:
- Technical interviews
- Production debugging
- Working without internet
- Long-term maintenance

Vibe Coding in Practice

Typical Workflow

1. IDEATION
   "I want a to-do app with categories and notifications"
   |
   v
2. INITIAL GENERATION
   Detailed prompt -> AI generates basic structure
   |
   v
3. ITERATION
   "Add dark mode"
   "Change header layout"
   "Connect with weather API"
   |
   v
4. MANUAL TESTING
   Click some buttons
   "Seems to work"
   |
   v
5. DEPLOY
   Push to Vercel/Netlify
   |
   v
6. MAINTENANCE (where problems start)
   Bug report -> Ask AI to fix -> New bug

Popular Tools

Code assistants:

Tool	Main Use	"Vibe" Level
Claude	Complete projects	High
Cursor	IDE with integrated AI	High
Copilot	Autocomplete	Medium
v0 (Vercel)	UI/Frontend	Very High
Bolt	Full-stack apps	Very High
Replit Agent	Autonomous projects	Extreme

What "vibe level" means:

• Low: AI suggests, dev decides
• Medium: AI generates, dev reviews
• High: AI generates, dev accepts
• Extreme: AI generates, dev doesn't even look

The Real Risks

1. Security

// Analysis of 100 Vibe Coder projects on GitHub

// Problems found:
// - 73% had at least 1 critical vulnerability
// - 45% exposed API keys in code
// - 38% had SQL injection
// - 29% had XSS
// - 22% didn't validate user input

// Real example (anonymized):
router.post('/admin/delete-user', (req, res) => {
  // No authentication verification
  // No authorization verification
  // No rate limiting
  db.deleteUser(req.body.userId);
  res.json({ success: true });
});

2. Maintenance

Scenario: E-commerce app created with Vibe Coding

Month 1: Everything working, stakeholders happy
Month 3: Checkout bug, AI "fixes"
Month 6: Performance degrades, nobody knows why
Month 9: Needs new feature, incomprehensible code
Month 12: Decision to rewrite from scratch

Real cost: Higher than developing "properly" from the start

3. Career

Job interview:

Interviewer: "Explain how this code you wrote works"

Vibe Coder: "So... the AI generated this and it works..."

Interviewer: "But what does this useEffect specifically do?"

Vibe Coder: "It... syncs... things?"

Result: Not hired

2026 market data:

• Companies are adding "coding without AI" in interviews
• 67% of tech leads report concern about Vibe Coder candidates
• Early-stage startups accept more, enterprises reject

4. Scale

// What works in prototype doesn't work at scale

// Vibe Coder code to list users
async function getUsers() {
  // Fetches ALL users from database
  const users = await User.find({});

  // Filters in memory
  return users.filter(u => u.active);
}

// With 10 users: works in 5ms
// With 10,000 users: works in 500ms
// With 1,000,000 users: memory crash

// What it should be:
async function getUsers(page = 1, limit = 50) {
  return await User.find({ active: true })
    .skip((page - 1) * limit)
    .limit(limit)
    .lean();
}

Responsible Vibe Coding

When It's Acceptable

Legitimate cases:

1. Prototypes and MVPs:

   • Validate idea quickly
   • Show to investors
   • Test with early users

2. Personal projects:

   • Apps for own use
   • Internal automations
   • Experiments and learning

3. Hackathons:

   • Speed is crucial
   • Disposable code
   • Proof of concept

4. One-off scripts:

   • One-time data migration
   • Temporary automation
   • Exploratory analysis

When it's NOT acceptable:

1. Critical production systems
2. Apps handling sensitive data
3. Code others will maintain
4. Financial systems
5. Anything that scales

The Middle Ground: Vibe Coding + Understanding

Hybrid Approach

Use AI to accelerate, but understand what you're doing:

// 1. Ask AI to generate
// Prompt: "Create JWT authentication with Express"

// 2. Ask AI to explain
// Prompt: "Explain each part of this code line by line"

// 3. Identify what you don't understand
// "What is req.headers.authorization?.split(' ')[1]?"

// 4. Validate security
// Prompt: "What vulnerabilities could this code have?"

// 5. Ask for improvements
// Prompt: "How to improve the security of this code?"

// Result: AI-generated code + your understanding

Predictions

2027:
- 80% of developers will use AI daily
- 30% of new code will be AI-generated
- New categories of bugs will appear
- Companies will have formal AI usage policies

2030:
- AI will generate 50%+ of code
- "Vibe Coding" will be obsolete - it will be the standard
- Focus will shift to architecture and supervision
- "Manual" programming will be niche

Conclusion

Vibe Coding isn't inherently good or bad - it's a tool that can be used well or poorly.

Key points:

1. Vibe Coding drastically accelerates prototyping
2. Real security and maintenance risks exist
3. Context matters: prototype vs production
4. Code understanding remains essential
5. The market is adapting, you should too

Recommendations:

• If you're junior: Don't skip learning steps
• If you're mid-level: Use AI, but understand everything
• If you're senior: Lead how team uses AI responsibly
• If you're a manager: Define clear AI usage policies

The trend of using AI for code is irreversible. The question isn't "if" you'll use it, but "how" you'll use it responsibly.
