Software development is changing faster than at any point in its history. In early 2025, Andrej Karpathy — a founding member of OpenAI and former head of AI at Tesla — introduced a term that captured something many developers were already feeling: vibe coding. The idea is simple. Instead of writing every line of code by hand, you describe what you want to an AI and let it generate the implementation. You guide the direction, review the output, and iterate. Tools like Teta, Cursor, and Bolt have turned this from a novelty into a daily workflow for thousands of builders shipping real products.
What Is Vibe Coding? Definition and Origin
Vibe coding is a style of software development where the programmer describes their intent in natural language and an AI model writes the code. The term was coined by Andrej Karpathy in February 2025 in a post on X (formerly Twitter), where he described a new way he had been building software:
"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."
The core idea is that the developer focuses on what they want the software to do — the product vision, the user experience, the business logic — and delegates the how to an AI. You might type something like "add a pricing page with three tiers, a free plan, a pro plan at $19/month, and an enterprise plan with a contact-us button" and watch the AI scaffold the entire page, complete with styling, responsive layout, and interactive elements.
This is different from using AI as an autocomplete assistant. With vibe coding, the AI is not finishing your sentences — it is writing entire features. You are the architect and the reviewer, not the typist.
The phrase resonated because it named something that felt genuinely new. Developers had been using GitHub Copilot for inline suggestions since 2021, but vibe coding described a higher-level workflow: chatting with an AI, describing outcomes, and building at a pace that was previously impossible for a single person.
How Vibe Coding Works in Practice
A typical vibe coding session looks nothing like a traditional development workflow. There is no blank editor, no boilerplate setup phase, and no Stack Overflow tab open in the background.
Here is what the process actually looks like:
Start with a description. You open a vibe coding tool and describe your project. "I want a SaaS landing page with a hero section, feature grid, testimonial carousel, and a sign-up form that saves to a database."
The AI generates code. The model produces a full implementation — files, components, routes, styles. In a tool like Teta, this happens inside a cloud sandbox, so you see a live preview immediately.
You review and iterate. Maybe the spacing is off, or you want a different color scheme. You say "make the hero taller and change the primary color to dark blue." The AI modifies the relevant code.
You keep building. Add authentication. Connect a database. Wire up a payment flow. Each feature is a conversation, not a coding session.
You deploy. When you are happy with the result, you ship it. Many vibe coding tools support one-click deployment to platforms like Vercel or Netlify.
The key shift is that the feedback loop is measured in seconds, not hours. You describe, you see, you adjust. The "vibe" is the creative flow that emerges when the gap between idea and implementation nearly disappears.
Best Vibe Coding Tools in 2026
The vibe coding ecosystem has matured rapidly. Here are the tools that define the space today:
Teta — An AI-powered app builder focused on SvelteKit. Teta combines a chat interface, a visual point-and-click editor, and a full VS Code environment in the browser. You describe features in chat, tweak designs visually, and drop into code when you need full control. Built-in Supabase integration handles database and auth, and one-click Vercel deployment gets your app live. It is the only tool in this category that is SvelteKit-first.
Bolt.new — A browser-based AI coding tool from StackBlitz that generates full-stack applications from prompts. Bolt runs everything in WebContainers, so there is no server-side sandbox. It supports multiple frameworks and has become one of the most popular vibe coding platforms, reportedly generating over $100M in annual revenue.
Lovable — Formerly GPT Engineer, Lovable focuses on turning descriptions into deployed web apps. It emphasizes design quality and has strong support for React-based projects. The interface is minimal: describe, preview, deploy.
Cursor — A VS Code fork with deep AI integration. Cursor is less of a "describe and generate" tool and more of an AI-augmented IDE. It works well for developers who want AI assistance while still writing code themselves. The Composer feature allows multi-file edits from a single prompt.
Replit — A cloud IDE with an AI agent that can build and deploy applications. Replit is particularly strong for beginners and has a large community. Its agent mode walks users through building complete apps step by step.
v0 by Vercel — A generative UI tool that produces React components from text descriptions. v0 is narrower in scope than the others — it generates UI components rather than full applications — but the quality of its output is high.
Pros and Cons of Vibe Coding
Advantages
- Speed. Building a functional prototype in an afternoon instead of a week is now routine. Vibe coding compresses the time between idea and working software.
- Accessibility. People who are not professional developers can build real applications. A product manager can prototype a dashboard. A designer can build an interactive mockup that is actually a working app.
- Reduced boilerplate. Nobody enjoys writing setup code, configuration files, or standard CRUD endpoints. AI handles the repetitive parts so you can focus on what makes your project unique.
- Exploration. When generating code is nearly free, you can try more ideas. Build three versions of a feature and pick the best one.
Disadvantages
- Understanding gaps. If you do not understand the code the AI writes, you cannot debug it effectively. This creates a fragile relationship where you depend on the AI to fix its own mistakes.
- Quality ceiling. AI-generated code works well for common patterns but can struggle with complex business logic, edge cases, or performance-critical sections.
- Security risks. Code you did not write is code you did not audit. AI models can introduce vulnerabilities, especially around authentication, input validation, and data handling.
- Vendor dependency. Your workflow depends on the AI tool being available, accurate, and affordable. If the API goes down or the pricing changes, your process breaks.
Vibe Coding vs Traditional Coding
Vibe coding does not replace traditional software engineering. It changes the ratio of time spent on different activities.
In traditional development, a significant portion of your day goes to implementation mechanics: looking up API syntax, wiring components together, writing tests for standard behavior, configuring build tools. The creative and architectural decisions — what to build, how the pieces fit together, what trade-offs to make — occupy a smaller slice of the total time.
Vibe coding inverts this. The implementation happens quickly, so you spend more time on the decisions that matter: product direction, user experience, system architecture, and code review.
Think of it as the difference between hand-drawing every frame of an animation and using motion design software. The tool handles the interpolation; the artist focuses on the keyframes.
For experienced developers, vibe coding is a multiplier. You know what good code looks like, so you can evaluate AI output critically, catch mistakes quickly, and guide the model toward better solutions. For beginners, it is a learning accelerator — you can build things that would be beyond your skill level, then study the generated code to understand how they work.
The two approaches are not mutually exclusive. Many developers vibe code to get a first draft, then switch to traditional coding for refinement. Teta supports exactly this workflow: chat with the AI to generate features, then open the VS Code editor to fine-tune the implementation.
When to Use Vibe Coding
Vibe coding is particularly effective in these scenarios:
- Prototyping and MVPs. When you need to validate an idea quickly, vibe coding gets you to a working product faster than any other approach.
- Landing pages and marketing sites. These are largely layout and content, which AI handles well.
- Internal tools. Dashboards, admin panels, and CRUD apps follow predictable patterns that AI models have seen thousands of times.
- Learning a new framework. Describing what you want and seeing how the AI implements it in an unfamiliar framework is one of the fastest ways to learn.
- Solo projects. When you are a team of one, vibe coding gives you the output of a small team.
It is less suited for projects that require novel algorithms, complex distributed systems, or code that must meet strict regulatory or performance requirements. In those cases, you want a human who deeply understands the domain writing the critical paths.
The Future of Vibe Coding
Vibe coding is not a trend. It is the early stage of a fundamental shift in how software gets built.
As language models improve, the gap between what you can describe and what the AI can build will continue to shrink. Today, you might need to provide detailed instructions for complex features. In a year, a single sentence might be enough.
Several developments are shaping where this goes next:
- Better context windows. As models handle larger contexts, they can understand entire codebases at once, leading to more coherent multi-file changes.
- Multimodal input. Drawing a wireframe on a whiteboard and having the AI turn it into a working page is already possible in some tools. This will become standard.
- Specialization. General-purpose AI coding tools will give way to domain-specific ones — tools optimized for e-commerce, for SaaS, for mobile apps, for data dashboards.
- Quality improvements. AI-generated code will get better at handling edge cases, writing tests, and following security best practices.
The developers who thrive in this future will be the ones who learn to work with AI effectively — who can describe clearly, review critically, and combine AI speed with human judgment. Vibe coding is not the end of programming. It is programming with a new set of tools, and those tools are getting better every month.
