Vibe coded too close to the sun? MultiTool has aloe for that burn

So you just vibe coded your way through a long weekend and now you have…something.

• A vaguely functional SaaS app that forgets user sessions every second business day.
  
• A web dashboard that looks great unless you open it in Firefox, where it catches fire.
  
• An AI chatbot that confidently answers every question with hardcoded responses from 2022.

It started innocently enough. You saw a few posts about “vibe coding” on Hacker News. Then, it spread to your social feeds. Finally someone on your team said they built a working CRM in 90 minutes using only prompts. So you gave it a shot.

Now your repo has 47 files, two frontend frameworks, and zero tests. But it runs!

Let’s rewind: what is vibe coding, and why is everyone suddenly doing it?

What is vibe coding?

Vibe coding is an emerging practice of using AI to generate most (or all) of your code, by describing what you want in natural language and letting large language models (LLMs) take the wheel. Andrej Karpathy–who popularized the term–sums it up best: "It's not really coding—I just see stuff, say stuff, run stuff, and copy-paste stuff, and it mostly works."

It’s programming by vibe instead of by plan. You prompt. AI responds. You deploy. (Code breaks.) Repeat.

There’s no denying the trend. GitHub Copilot, Claude, ChatGPT, and others have brought autocomplete to the next level. The 2024 Stack Overflow Developer Survey found that 82% of developers currently using AI tools use them to write code. It’s fast, it’s fun, and it feels like a superpower.

But like any superpower, AI-assisted code comes with unintended side effects.

The dark side of the vibe

According to the 2024 DORA State of DevOps report, one in three teams that adopted AI coding tools saw  an increase in production bugs. Some teams reported a 50% uptick in regressions traced back to AI-generated code.

When you're copy-pasting functions you didn’t write, that call APIs you didn’t know you had, it's easy to ship code you don’t fully understand.

What can happen if you vibe-code first and read later:

• Your API route is returning sensitive user data because the AI skipped authentication middleware in the scaffold.
• Your database migration is dropping and recreating a table on every deployment, and you didn’t notice until prod data vanished.
• You have a frontend form with no input validation, because the AI assumed the backend would handle it, and now Little Bobby Tables is knocking at your door.

Balancing out the AI

While it’s possible to vibe code a little too close to the sun, we’re not here to scold anyone for using intelligent code generation. AI-assisted development is here to stay whether it works or not. So instead of shunning it, we need better ways to counterbalance its less desirable outcomes.

We built MultiTool to give you confidence in what’s going out the door:

• Automatically detect if your vibe-coded feature is quietly on fire. MultiTool compares your new deployment to the baseline version in real time, using statistical models to detect increases in error rates, latency, or other regressions before users start filing tickets.

• Let the agent take the wheel. If your new version behaves well, MultiTool auto-promotes it across your fleet. If something goes sideways, it auto-rolls back. No human intervention, no 2AM hotfix.
• Ship faster, without the fear. Whether you’re shipping handcrafted code or GPT-assisted “trust me, bro” commits, MultiTool gives you the safety net to deploy as often as you want, without putting end users at risk.

It’s not about fighting the vibe. It’s about shipping safely in spite of it.

TL;DR

Vibe coding is fun. It’s fast. It’s a part of the future. But when your whole stack is built on vibes and GPT-generated spaghetti, you need something solid underneath.

If you’re interested in using MultiTool as your failsafe, the MultiTool beta is free to try. We’d love to be your backup for when your AI wingman decided DROP TABLE was the vibe.
