In February 2025, OpenAI co-founder Andrej Karpathy coined a term that would define the year: "vibe coding." By March, it was in the Merriam-Webster Dictionary. By November, Cursor (the AI coding IDE) raised $2.3 billion at a $29.3 billion valuation. Welcome to the future of programming.

What Is Vibe Coding?

Vibe coding is a software development approach where you use natural language prompts to command AI to generate code. Instead of writing code yourself, you describe what you want, and the AI builds it.

Andrej Karpathy described it in his viral February 2025 tweet:

"A new kind of coding... where you fully give in to the vibes, embrace exponentials, and forget that the code even exists."

The concept exploded across Silicon Valley. Within a month, Merriam-Webster added "vibe coding" as a "slang & trending" term.

The Fastest-Growing Startup in History?

Lovable, one of the leading vibe coding platforms, may have achieved something unprecedented:

  • $100 million ARR in just 8 months - potentially the fastest-growing startup in history
  • Users can build full-stack web applications without writing any code
  • Just describe your idea in plain English, and Lovable generates the app

Meanwhile, Anysphere - the company behind Cursor - raised $2.3 billion in November 2025, valuing the company at $29.3 billion. It was their second massive funding round of the year.

The Big Three: Cursor vs. Bolt vs. Lovable

Cursor - For Professional Developers

Cursor is an AI-powered IDE (Integrated Development Environment) built as a fork of Visual Studio Code. It's designed for developers who want AI assistance while maintaining control over their code.

Key features:

  • Code generation from natural language
  • Smart rewrites and refactoring
  • Codebase queries - ask questions about your project
  • Integrates with existing developer workflows

Best for: Professional developers who want AI assistance but still want to understand and control their code.

Bolt.new - Web Apps in Minutes

Bolt.new by StackBlitz is a web-based AI development environment that generates working web applications instantly from text prompts.

Key features:

  • Generate complete apps from descriptions
  • Browser-based - no installation needed
  • Free plan includes 1M tokens/month (limited to 150k daily)
  • Paid plans start at $20/month with 10M tokens/month

Best for: Rapid prototyping and building MVPs quickly.

Lovable - No Code Required

Lovable is an AI-powered platform that helps users build full-stack web applications without writing any code. Describe your idea in plain English, and it generates the app.

Key features:

  • Truly no-code - designed for non-programmers
  • Full-stack applications from text descriptions
  • Rapid iteration based on feedback

Best for: Non-technical founders, entrepreneurs, and anyone who wants to build apps without learning to code.

Other Notable Vibe Coding Tools

Replit

Replit is a browser-based IDE that has added powerful AI features for code generation. It recently debuted on major AI tool lists and is popular for its accessibility.

GitHub Copilot

GitHub Copilot remains the most widely used AI coding assistant, integrated directly into VS Code, JetBrains IDEs, and more. It's less "vibe coding" and more "AI pair programming."

Windsurf (by Codeium)

Windsurf is another AI-powered IDE gaining traction as an alternative to Cursor.

The Reality Check: Limitations of Vibe Coding

Before you abandon traditional programming, some important caveats:

The 60-70% Problem

According to multiple reviews, vibe coding tools often produce a 60-70% solution that requires manual coding to be production-ready. They're excellent for prototyping but may not be suitable for complex, production applications.

The METR Study

A rigorous study published in July 2025 by METR found something counterintuitive:

"Experienced developers using AI tools like Cursor and Claude actually took 19% longer to complete tasks, despite believing they were 20% faster."

This suggests a potential productivity illusion - feeling faster while actually being slower. However, this may not apply to all use cases, and the tools are improving rapidly.

Skill Level Matters

The tools work differently depending on your background:

  • Cursor rewards existing knowledge - Developers who understand code can guide the AI more effectively
  • Lovable caters to beginners - But may produce code that's harder to customize or debug

The Hybrid Workflow

According to multiple user testimonials, many successful teams use a hybrid approach:

  1. Prototype with Lovable or Bolt - Get a working version quickly
  2. Export to GitHub - Sync the generated code to a repository
  3. Refine with Cursor - Fix issues, customize, and add features
  4. Deploy and iterate - Continue development in traditional or hybrid mode

This approach lets you move fast during ideation while maintaining code quality for production.

Pricing Overview

Tool Free Tier Paid Plans
Cursor Limited $20/month
Bolt.new 1M tokens/month From $20/month
Lovable Limited Various tiers

Who Should Use Vibe Coding Tools?

Great For:

  • Non-technical founders who want to validate ideas quickly
  • Developers doing rapid prototyping before investing in full development
  • Small businesses that need simple apps without hiring developers
  • Learning to code - see how AI approaches problems
  • Internal tools that don't need to be perfect

Use Caution For:

  • Complex production applications - may need significant refinement
  • Security-critical applications - generated code should be audited
  • Highly customized projects - may be faster to code from scratch

The Future of Vibe Coding

With Cursor at $29.3 billion valuation and Lovable potentially the fastest-growing startup ever, vibe coding isn't a fad - it's a fundamental shift in how software gets built.

The trajectory is clear: AI will handle more and more of the actual code writing, while humans focus on describing what they want and refining the results. Whether that means traditional programming disappears or just evolves remains to be seen.

For now, the smart move is to experiment with these tools, understand their strengths and limitations, and find where they fit in your workflow.
