Vibe Coding Explained: What Karpathy's Viral Term Really Means
Almost a year ago, Andrej Karpathy tweeted about a "new kind of coding" that would change everything. He called it vibe coding—where you "fully give in to the vibes, embrace exponentials, and forget that the code even exists." What started as a tweet has become a movement that's redefining how we build software.
The Birth of a Movement
"There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists. It's possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good."
— Andrej Karpathy, February 6, 2024
Karpathy wasn't just coining a catchy term. The former Tesla AI director and OpenAI co-founder was describing his actual workflow: using voice input with SuperWhisper, barely touching the keyboard, accepting all AI suggestions without reading the diffs, and letting code grow beyond his usual comprehension.
When something breaks? Just copy-paste the error message with no comment. Can't fix a bug? Work around it or ask for random changes. This wasn't careful, methodical programming—it was vibing with the machine.
Within a month, "vibe coding" was trending in the Merriam-Webster Dictionary. The New York Times, Guardian, and tech blogs everywhere were discussing what this meant for the future of programming. But here's the thing: not everyone was using the term the same way.
The Tools Making It Real
Three tools have emerged as the vibe coding trinity, each taking a different approach to the same goal: letting developers focus on what to build, not how to type it.
Cursor: The Editor That Started It All
Cursor's Composer mode (hit Cmd+I) was Karpathy's tool of choice. It doesn't ask permission—it just implements your ideas across multiple files. The December 2024 Agent mode update took it further: no need to specify context files, automatic shell command generation, and the ability to understand entire projects at once.
The vibe: "Make this thing work" → watches as files appear and code flows across your screen
Claude Code: The Terminal Companion
Anthropic's CLI tool lives in your terminal. Install with npm install -g @anthropic-ai/claude-code, and it becomes an agentic platform that understands your entire codebase. Through MCP (Model Context Protocol), it connects to GitHub, databases, and APIs without leaving your terminal.
The vibe: Natural language in the terminal → complete features implemented
Conductor: The Orchestrator
The newest player changes the game entirely. This Mac app lets you run multiple Claude Code agents in parallel, each in an isolated workspace (using git worktrees). Assign one agent to refactor the backend while another updates the frontend and a third writes tests—all simultaneously.
The vibe: You're the conductor, AI agents are your orchestra
What Vibe Coding Actually Looks Like
Let's be real about what vibe coding means in practice. Simon Willison, creator of Datasette, puts it bluntly: it's "building software with an LLM without reviewing the code it writes."
The Vibe Coding Workflow
- 1.Voice your intent: Use tools like SuperWhisper to describe what you want. "I need a dashboard that shows user activity over time with filterable date ranges."
- 2.Accept the flow: Watch as AI generates components, APIs, database schemas. Don't read the diffs. Trust the process.
- 3.Error? Copy-paste: Something breaks? Copy the error message, paste it back. No explanation needed. The AI figures it out.
- 4.Iterate by feel: "Make it more responsive." "Add a dark mode." "This feels slow." Guide by vibes, not specifications.
This approach horrifies traditional developers—and for good reason. You're deliberately choosing not to understand the code you're shipping. But Karpathy's point was about prototyping, about weekend projects, about exploring ideas at the speed of thought.
The magic happens when you combine vibe coding with tools like Conductor. Now you're not just vibing with one AI—you're conducting an entire symphony of agents, each handling different aspects of your vision while you maintain the high-level direction.
The Reality Check
Here's what the evangelists won't tell you: vibe coding isn't replacing traditional development. It's creating a new tier of software—prototypes that actually work, MVPs that ship in hours instead of weeks, and experiments that would never have been worth the time investment before.
Perfect for:
- • Hackathon projects
- • Proof of concepts
- • Personal tools and scripts
- • Learning new frameworks
- • Rapid prototyping
Risky for:
- • Production systems
- • Security-critical code
- • Performance-sensitive applications
- • Long-term maintainable codebases
- • Team projects requiring code reviews
The professionals using AI coding tools aren't really vibe coding—they're AI-assisted coding. They review diffs, understand the architecture, and maintain quality standards. They use Claude Code and Cursor as incredibly powerful assistants, not as black boxes.
The Cultural Shift
Whether you call it vibe coding, AI-assisted development, or something else entirely, something fundamental has changed. The barrier between idea and implementation is dissolving. A designer can build a working prototype. A product manager can test a feature hypothesis. A founder can create an MVP without hiring developers.
This isn't about replacing developers—it's about expanding who can create software. Just like WordPress didn't eliminate web developers but created millions of websites that wouldn't have existed otherwise, vibe coding is expanding the universe of what gets built.
"The hottest new programming language is English."
— Andrej Karpathy, 2023
Karpathy saw this coming. His 2023 prediction that English would become a programming language wasn't hyperbole—it was a roadmap. Vibe coding is just the first step toward a world where technical implementation is no longer the bottleneck for innovation.
What This Means for You
If you're discovering vibe coding for the first time, here's what you need to know:
For Non-Developers
You can now build things. Real, working software. Start with Cursor and a weekend project. Don't worry about understanding every line—focus on making something that solves a problem you have.
For Developers
Your expertise is more valuable than ever. You're the one who knows when to vibe and when to be meticulous. You can guide AI to build production-quality code, architect systems that scale, and review what the machines produce. Tools like Conductor multiply your effectiveness—you can now manage multiple development streams simultaneously.
For Teams
Start experimenting with AI-assisted workflows. Set up Claude Code with MCP servers for your stack. Try Conductor for parallel development tasks. But maintain code review standards—vibe coding for prototypes, professional standards for production.
The tools are evolving rapidly. Cursor's Agent mode, Claude Code's MCP integrations, Conductor's parallel workspaces—these are just the beginning. The question isn't whether to adopt AI coding tools, but how to use them effectively for your specific needs.
