What Even Is Vibe Coding?
Andrej Karpathy posted a tweet in February 2025 that blew up. He described a new way of writing software where you “fully give in to the vibes, embrace exponentials, and forget that the code even exists.” That’s vibe coding in a nutshell.
Instead of typing out every function and debugging line by line, you describe what you want in plain English. An AI model generates the code. You run it. If something breaks, you tell the AI what went wrong. Rinse, repeat.
The term hit Merriam-Webster as “slang & trending” within weeks. Collins English Dictionary named it their Word of the Year for 2025. By early 2026, it’s gone from a meme to a legitimate development approach used by solo founders, designers, and even experienced engineers prototyping ideas.
How Vibe Coding Actually Works
Here’s what a typical vibe coding session looks like. You open a tool like Cursor, Replit, or Bolt.new. You type something like “build me a landing page with a waitlist form that saves emails to a database.” The AI generates the code. You hit run.
That’s… basically it. The key difference from traditional AI-assisted coding is that you don’t review the code line by line. You care about the output, not the implementation. Simon Willison put it well: if you’ve reviewed and understood every line the AI wrote, that’s not vibe coding – that’s just using an AI as a typing assistant.
The workflow goes something like this:
- Describe what you want in natural language
- AI generates the code
- You test the result
- If it works, move on. If not, describe the problem
- AI fixes it
There’s no flowchart or formal methodology. You’re navigating by feel. Hence “vibes.”
The Tools People Are Using
The vibe coding ecosystem has exploded in the past year. Here’s what’s getting real traction:
| Tool | Best For | Starting Price |
|---|---|---|
| Cursor | Professional developers wanting AI in their IDE | Free (Pro $20/mo) |
| Replit | Full-stack apps from a single prompt | Free (Core $25/mo) |
| Bolt.new | Quick web app prototypes | Free tier available |
| Lovable | Non-technical founders building MVPs | $20/mo |
| Windsurf | VS Code users wanting deep AI integration | Free (Pro $15/mo) |
| Claude Code | Terminal-based agentic coding | API pricing |
| v0 by Vercel | React/Next.js UI generation | Free tier |
I’ve spent the most time with Cursor and Claude Code personally. Cursor feels like VS Code with superpowers – the agent mode they launched in late 2025 can handle multi-file refactors that would’ve taken me hours. Claude Code is different, it runs in your terminal and acts more like a pair programmer who can actually execute commands.
Replit and Bolt.new are where non-developers tend to start. You can go from “I want a recipe app” to a working deployed app in under 30 minutes. Not production-grade, but functional enough to test an idea.
Who’s Actually Doing This?
Three main groups:
Non-technical founders. This is the biggest growth area. People with business ideas but no coding background are shipping real products. A friend of mine built a customer feedback tool for his consulting business in two weekends using Bolt.new. It’s not elegant code, but his clients use it daily.
Designers and product people. Instead of waiting for engineering to build a prototype, designers are generating functional demos themselves. One PM I talked to said she vibe-coded an internal dashboard that her team still uses six months later.
Experienced developers prototyping. Look, if I need to test whether an idea works, I’m not spending two days setting up proper architecture. I’ll vibe-code a rough version in an hour, see if the concept holds, then decide whether to build it properly. Most experienced devs I know use it this way.
What You Can Realistically Build
Let’s be honest about what vibe coding can and can’t handle right now.
Works well:
- Landing pages and marketing sites
- CRUD apps (to-do lists, inventories, simple dashboards)
- Internal tools and admin panels
- Browser extensions
- Data scrapers and automation scripts
- Simple mobile apps via React Native or Flutter
- API integrations and webhooks
Gets messy fast:
- Real-time collaborative features (think Google Docs)
- Complex authentication and authorization systems
- Anything processing payments at scale
- Machine learning pipelines
- Performance-critical applications
The pattern is clear. If your app is mostly standard patterns that LLMs have seen millions of times in training data, vibe coding works great. The moment you need novel architecture or edge-case handling, you’ll start running into walls where the AI confidently generates code that looks right but breaks in subtle ways.
The Security Problem Nobody Wants to Talk About
Here’s the thing. When you accept code without reviewing it, you’re also accepting whatever vulnerabilities come with it. And AI-generated code has a track record of introducing security issues.
A Stanford study found that developers using AI assistants produced less secure code than those writing it manually. The AI doesn’t intentionally write insecure code, but it optimizes for “works” not “works safely.” SQL injection, hardcoded credentials, missing input validation – these show up regularly in vibe-coded projects.
For a personal project or internal tool? Probably fine. For anything handling user data or processing payments? You absolutely need someone who understands security to review the output. Vibe coding the frontend and letting an experienced developer handle auth and data layers is a solid compromise.
Vibe Coding vs Traditional AI-Assisted Development
People mix these up constantly, so let me clarify.
| Aspect | Vibe Coding | AI-Assisted Development |
|---|---|---|
| Code review | Minimal to none | Developer reviews everything |
| Who’s in control | The AI, mostly | The developer |
| Code understanding | Optional | Required |
| Best for | Prototypes, MVPs, personal projects | Production software |
| Speed | Very fast | Fast |
| Code quality | Unpredictable | Higher |
| Skill needed | Prompt writing, testing | Programming + prompt skills |
GitHub Copilot autocompleting your functions? That’s AI-assisted development. Telling Claude “build me a full expense tracker app” and shipping whatever it produces? That’s vibe coding.
Many developers land somewhere in between. They’ll vibe-code the initial structure, then switch to careful review mode for anything that matters. The terminology is less important than understanding the spectrum.
Tips for Getting Better Results
After months of vibe coding various projects, here’s what I’ve learned actually matters:
Be specific with your first prompt. “Build me a website” gives garbage. “Build a single-page React app with a hero section, three feature cards, a pricing table with two tiers, and a footer with social links. Use Tailwind CSS, dark theme” gives something usable on the first try.
Keep context small. AI models have context windows, and they get confused when you dump an entire codebase into the conversation. Work on one feature at a time. Start new conversations for new features.
Screenshot your bugs. Seriously. Most vibe coding tools now accept images. Instead of trying to describe a CSS layout issue in words, just paste a screenshot and say “the sidebar overlaps the main content on mobile.” Way faster.
Version control even if you don’t code. Git isn’t just for developers. When your AI generates a working version, commit it. You will break things. Having a “last known good” version saves hours of “undo my last 15 changes.”
Know when to stop. If you’ve gone back and forth with the AI more than 5-6 times on the same bug, something structural is wrong. Either simplify your approach or bring in someone who can read the code.
The Business Case for Vibe Coding
Companies are taking this seriously. McKinsey’s 2025 tech report found that organizations using AI-assisted development (including vibe coding) reduced time-to-market for internal tools by 40-60%. Forbes reported in February 2026 on five enterprise use cases, from internal chatbots to custom analytics dashboards.
The math is straightforward. A simple internal tool that would cost $15,000-$30,000 from a freelancer or agency can be vibe-coded by someone on the team for the cost of a $20/month subscription. It won’t be as polished or maintainable, but for tools used by 10-20 people internally, it doesn’t need to be.
Startups are especially aggressive here. Y Combinator’s Winter 2026 batch had multiple founders who built their initial MVPs entirely through vibe coding before hiring their first engineer. The bar for “technical co-founder” is shifting.
What Critics Get Right (and Wrong)
The pushback against vibe coding falls into a few camps.
“It produces unmaintainable code.” Largely true. AI-generated code tends to be verbose, inconsistent in style, and poorly organized. If you’re building something that needs to last years and be maintained by a team, vibe coding the whole thing is a bad idea. But for prototypes and short-lived projects? Maintainability barely matters.
“It’s going to kill junior developer jobs.” More nuanced than it sounds. Yes, some entry-level tasks are being automated. But the demand for people who can understand and fix AI-generated code is growing. The job is changing, not disappearing. Knowing how to prompt effectively and validate AI output is becoming a real skill.
“People will ship insecure garbage.” This is the most valid concern. And it’s already happening. We’re going to see vibe-coded apps with data breaches. The solution isn’t to ban the practice – it’s better tooling for automated security scanning of AI-generated code. Companies like Snyk and Semgrep are already building this.
Where This Is Heading
Gartner included “AI-native development” in their Top Strategic Technology Trends for 2026. The analyst firm predicts that by 2028, 75% of new enterprise applications will involve some form of AI-generated code.
The tools are getting better fast. Cursor’s background agents (announced February 2026) can work on tasks autonomously while you do other things. Replit’s AI can now deploy apps to production with a single prompt. Claude’s computer use capabilities mean the AI can literally operate your development tools for you.
My prediction: within a year, the line between “vibe coding” and regular development will blur significantly. AI code generation will just be… how software gets built. The debate won’t be whether to use AI, but how much oversight the AI needs for different types of projects.
Should You Try It?
If you have a software idea and no coding background, absolutely yes. Start with Replit or Bolt.new, try building something small, and see how far you get. Worst case, you wasted an afternoon. Best case, you have a working prototype.
If you’re a developer, you’re probably already doing some version of this. The question is how much you let go of the reins. For side projects and experiments, go full vibes. For work that ships to customers, keep your review hat on.
If you’re a manager or founder, understand that this changes your hiring calculus. A team of 3 developers with good AI tools can match what a team of 8 did two years ago for standard CRUD applications. The savings are real. So are the risks if nobody on the team understands the generated code.
Vibe coding isn’t going to replace software engineering. But it’s already replacing a lot of the grunt work. The developers who thrive will be the ones who learn to work with AI as a genuine collaborator, not just a fancy autocomplete.
FAQ
Do I need to know how to code to try vibe coding?
No. That’s the whole point. Tools like Replit, Bolt.new, and Lovable are designed for people with zero programming experience. You describe what you want, the AI builds it. Having some technical understanding helps you debug issues faster, but it’s not required to get started.
Is vibe coding free?
Most tools have free tiers. Cursor offers a free plan with limited AI requests. Replit, Bolt.new, and v0 all have free options. For serious use, expect to pay $15-25/month. Compared to hiring a developer, it’s basically nothing.
Can I build a real business on vibe-coded software?
People are doing it right now. But be smart about it. Validate the idea with a vibe-coded MVP, then invest in proper engineering if the business gains traction. Running a company on code nobody understands is a ticking time bomb.
Which vibe coding tool should I start with?
Non-developers: Replit or Bolt.new. They handle everything from code generation to hosting. Developers: Cursor or Windsurf. They integrate into your existing workflow. Check our best AI code editors roundup for a detailed comparison.
Is vibe-coded software secure?
Not by default. AI models prioritize functionality over security. If your app handles sensitive data, get a security review. Use automated scanning tools like Snyk or GitHub’s code scanning. Never vibe-code authentication or payment processing without expert review.
