Vibe coding started taking off in 2025: you describe in natural language what you want to build, let AI generate, modify, and debug the code, and the focus shifts from “writing line by line” to “describing what you want, checking results, and iterating.” The term is generally credited to Andrej Karpathy, who introduced it in early 2025.
Why it caught on is straightforward. The barrier to building a website or app dropped significantly. Where you used to need to know a programming language and set up a development environment, now you can describe an idea in a sentence and have a working prototype in minutes, then refine from there. Below is a breakdown of the concept, the common tools, the basic workflow, and the security risks you actually need to care about.
What Vibe Coding Is
Traditional programming means you control every line. Vibe coding means you describe what you want clearly, let AI produce the code, and your job becomes “check whether the output is right, and tell it to fix what isn’t.”
The value is speed: the time from idea to something that actually runs shrinks dramatically, which makes it well-suited for prototyping and validating concepts. But because you may not understand every line of the generated code, “it runs” and “it’s safe to ship” are two different things — more on that below.
Common Tools
| Tool | What it does | Free plan | Paid starting price |
|---|---|---|---|
| Lovable | Generate and deploy full-stack web apps through chat | Yes (5 credits/day) | Pro ~US$25/month |
| Bolt.new | Build websites and web/mobile apps with prompts | Yes (300k tokens/day) | Pro ~US$25/month |
| Cursor | AI code editor that fits engineering workflows | Yes (Hobby) | Pro ~US$20/month |
| Replit | Turn ideas into apps in the browser using an Agent | Yes (Starter) | Core ~US$25/month |
(Pricing and limits should be verified on each tool’s official site.)
The rough split: Lovable and Bolt lean toward “one-click generation of deployable products” — the most intuitive starting point for beginners building a website prototype. Cursor is an AI editor aimed at people who already know how to code and want to go faster. Replit moves your development environment into the browser and uses an Agent to run it.
Basic Workflow
- Define the goal in a sentence — for example: “Build a to-do list where I can add tasks, check them off, and delete them.”
- Break the requirement into: screens, data, interactions, and whether you need deployment.
- Enter the prompt in your tool of choice and generate a first version.
- Preview it, call out what’s wrong, ask AI to fix it, and repeat for a few rounds.
- Before going live, do a manual code review, security check, and functional test. This step cannot be skipped.
Security Risks Worth Taking Seriously
This is the part of vibe coding that gets talked about least but matters most. Security firm Veracode’s 2025 testing (cited by ITPro) found that roughly 45% of AI-generated code contained insecure patterns. In other words, the AI helping you build something doesn’t mean what it built is secure.
The practical approach: use vibe coding as an accelerator for prototypes and internal tools. For anything customer-facing — especially features touching login, payments, or personal data — require an engineering review and security testing before you push to production. Never ship AI-generated code straight to a live environment.
Who It’s For
- Strong fit: anyone who wants to quickly validate an idea, build a website prototype, or put together a small internal tool — regardless of whether they can code.
- Watch out: when building something real for public use, you still need someone who can review the code, write tests, and handle security.
