Vibe coding: coding with AI in 2026 (Cursor, Claude Code)

Vibe coding is the new way of coding where you dialogue with AI. We explain how Cursor, Claude Code, Copilot and Windsurf radically change the dev job. 2-5x productivity, but not magic.

In one sentence

"Vibe coding" is this new way of coding where you describe what you want in natural language, and the AI writes the code for you. With Cursor, Claude Code, Windsurf, Copilot, in 2026 we've moved from "AI helps you" to "AI is your colleague". And it's radically changing the developer profession.

💻
The analogy that works
Before, coding was like driving a manual car: you mastered every lever, clutch, mechanic. Now vibe coding is driving an automatic: you say "I want to go to Lyon", the car handles the rest. You keep the steering wheel (strategic decisions) but let go of the details (syntax). Not all devs like it, but it's massively faster.

🤖 Want to understand AI agents?

Vibe coding tools are specialised AI agents. We explain how they work in detail.

Where does the term "vibe coding" come from?

The term exploded in early 2025 when Andrej Karpathy (ex-OpenAI, ex-Tesla) tweeted:

"I do what I call 'vibe coding' where I totally relax and let go. It's not really coding, I see stuff, say stuff, run stuff, and copy-paste stuff, and it mostly works."

→ The concept resonates. The dev community catches fire. Vibe coding enters the vocabulary.

The idea: you describe the intent, the AI produces the code. You no longer type each line. You vibe with your code.

How it works in practice

The vibe coding workflow

  1. You open your editor (Cursor, etc.)

    The AI sees your entire project: structure, files, dependencies.

  2. You describe what you want

    'Add a profile page with photo, bio and follow button', you speak, not code.

  3. The AI suggests the code

    The code appears directly in the right files. With imports, styling, everything.

  4. You validate or request adjustments

    'Put the button on the right, and make it turn red on hover.' The AI modifies.

  5. You test and deploy

    You run the code, check it works, and you push.

Cursor in practice: quick tour

Cursor became in 2025-2026 THE editor for indies. Here's what makes it special:

The 3 features that change everything
1. Intelligent tab autocomplete You start typing, Cursor predicts the entire function while keeping your project's style. You press Tab, it's done. 2. Cmd+K (edit by prompt) Select a piece of code, type Cmd+K, say what you want: "Refactor to TypeScript", "Add error handling", "Optimise for performance". The code changes. 3. Agent mode (Composer / Agent) The big leap of 2025. You say "Create a login page with Google OAuth" and the agent creates multiple files, modifies the config, installs dependencies, tests. Like a junior dev, but in 30 seconds.

Real productivity: x2 to x5 depending on tasks

Here are the real numbers observed in 2026:

Vibe coding productivity gains (by task type)

Basic CRUD (forms, lists)5x faster
Documentation / comments5x faster
Repetitive UI components4x faster
Unit tests4x faster
Refactoring3x faster
Debugging / hunting obscure bugs2x faster
Complex architecture / system design1x (little help)
Very precise perf optimisation1x (little help)

Reading: repetitive tasks (CRUD, UI, docs) are 5x faster. But on architecture or precise optimisation, AI helps little, these tasks remain deeply human.

The debate: vibe coding vs traditional coding

📚The 2 camps confronting each other in 2026

Pro vibe coding 🟢

Arguments:

  • Massive productivity: x3-5 on majority of tasks
  • Democratises: non-devs can create viable products
  • Makes code more accessible to juniors
  • Reduces fatigue: less syntax to memorise
  • Allows focus on design, architecture, user

Slogan: "Code is just a means, the goal is to ship product."

Anti vibe coding 🔴

Arguments:

  • Fragility: generated code can have subtle bugs undetected
  • Technical debt: juniors who don't learn → nightmare to maintain in 3 years
  • Security: AI can introduce vulnerabilities without realising
  • Dependency: if AI breaks down, you can't code anymore
  • Loss of expertise: deep understanding is lost

Slogan: "You don't master what you haven't written."

The 2026 reality

The truth is in the middle:

  • Expert devs use vibe coding as an accelerator, but review and challenge everything
  • Junior devs must use it with supervision to avoid becoming dependent
  • Non-devs can prototype but need a senior dev for serious prod

→ The right use: augmented intelligence, not replacement.

Classic vibe coding pitfalls

Mistakes to avoid in 2026
1. Trusting blindly AI can write code that works but with subtle bugs (off-by-one, race condition, XSS flaw). Always review, always test. 2. Skipping the fundamentals You MUST understand Git, HTTP, async, memory, basic security. Otherwise, you'll ship crap without knowing it. 3. Accumulating technical debt "It works, moving on", after 3 months, your project is unmanageable. Refactor regularly. 4. Pasting code snippets without context AI doesn't know you already have an auth system. It'll propose a new one that clashes. Always show context. 5. Ignoring security AIs often suggest code that's functional but insecure: SQL injection, passwords in plain text, secrets in code. Audit mandatory. 6. Overestimating your abilities You built an MVP in 3h? Cool. But scaling it, securing it, maintaining it = that's another job.

How to learn vibe coding?

🎓
Roadmap to becoming a vibe coding pro
Level 0 : Basics (1-3 months): - Learn the fundamentals: Python or JS, Git, terminal, HTTP - Without these basics, AI will lose you Level 1 : Basic tools (1 month): - Install Cursor or use GitHub Copilot - Start with small personal projects (todo list, calculator, scraper) - Learn to read generated code and modify it Level 2 : Agent mode (1-2 months): - Use agent modes (Cursor Composer, Claude Code) - Start architecting projects by talking to AI - Learn good prompting practices for code Level 3 : Pro (3-6 months): - You review every generated line - You understand when AI is wrong and correct it - You mix vibe coding and manual code according to tasks Bonus: follow Andrej Karpathy on YouTube, read tweets from @levelsio, @swyx.

Case study: creating an app in 1 weekend

With vibe coding in 2026, here's what 1 dev with 6 months' experience can do in 48h:

MVP Weekend in vibe coding mode
Friday evening (3h): Setup + idea - Idea: "App to track daily habits" - Setup: Next.js 15 + Postgres (Supabase) + Tailwind + auth - All generated by Cursor in 30 min Saturday morning (4h): Backend - DB schema (habits, users, completions) - API routes (CRUD) - Auth with Google OAuth Saturday afternoon (4h): Frontend - Habits listing page - Add page - Weekly stats - Responsive design Sunday morning (3h): Polish + bugs - Push notifications - Dark mode - Bug fixes Sunday afternoon (2h): Deploy + landing - Push to Vercel - Landing page on Framer - Open Twitter/Reddit to show off Total: ~16h effective work → functional and deployed MVP. Before vibe coding, this project would have taken 2-3 weeks minimum. That's the revolution.

Will vibe coding kill developers?

Honest answer in 2026
No, but it's changing the profession. Devs who disappear: - Those who did only CRUD without thinking - Those who copy-pasted Stack Overflow without understanding - Pure execution juniors without architecture capacity Devs who thrive: - Those who architect systems - Those who understand fundamentals deeply - Those who know when to use AI and when not to - Those who work on the hard stuff (perf, security, scale) Historical analogy: when Excel arrived, pure calculation accountants disappeared. But strategic accountants became even more valuable. Same for devs in 2026. Advice: don't be an execution dev. Be an architect dev. AI does the code, you do the system design, the business, the UX.

The metaphor that sums it all up

🚗
The shift to automatic cars
In the 80s-90s, driving a manual was a skill in itself. Today, 95% of new cars are automatic (in Europe). Drivers save mental energy, can focus on the road, less tired. But: knowing how to drive a manual remains useful in certain situations (mountains, sport, breakdown). And some purists prefer it. Vibe coding is exactly that: a massive shift to automatic. You save time, you focus on design, you go further. But mastering manual (real code) remains essential for critical moments (debug, perf, security). → The good 2026 dev knows how to do both. But lives in automatic mode day-to-day.

Absolutely remember

  • Vibe coding = coding by chatting with AI, democratised in 2025
  • Star tools: Cursor, Claude Code, Copilot, Windsurf, Replit
  • Productivity: x2 to x5 on majority of dev tasks
  • Limits: architecture, precise perf, deep debugging remain human
  • Pitfalls: blind trust, technical debt, security
  • Evolution of the profession: execution devs disappear, architects thrive

If you code in 2026, use these tools. If you refuse, you'll be 5x less productive than your peers. But use them with discernment, not like a script kiddie.
