VibeCheck for VS Code

Your safety net for coding with AI

AI writes your code. VibeCheck makes sure it actually works.

The Problem

You're building apps with AI — Cursor, Copilot, Claude, ChatGPT, Windsurf — and it feels like a superpower.

But here's something nobody tells you: AI makes things up. Confidently. Convincingly.

It'll create a login page that looks beautiful... but doesn't actually log anyone in. It'll add a "Save" button that does nothing when you click it. It'll show a dashboard full of numbers that are completely made up.

The worst part? Everything looks right. You'd never know something was broken just by reading the code. You ship it, your users try it, and... nothing works.

That's where VibeCheck comes in.

What Is VibeCheck?

VibeCheck is like spell-check, but for AI-generated code. It reads your project, understands how everything connects, and warns you when something is fake or broken — before you ever ship it.

AI does this...	VibeCheck tells you...
Creates a page that calls an API that doesn't exist	⛔ "This URL isn't real — there's no matching code for it"
Adds a button with no action behind it	⚠️ "This button won't do anything when clicked"
Shows a dashboard with hardcoded numbers	⚠️ "These numbers are fake — they're not coming from real data"
Writes code that silently hides errors	⚠️ "If something breaks here, you'll never know about it"
References a config setting that doesn't exist	⛔ "This setting isn't set up anywhere in your project"

Getting Started (3 Minutes)

Step 1 — Install

Search "VibeCheck" in the Extensions sidebar and hit Install. That's it.

Step 2 — Open Your Project

There's nothing to configure. VibeCheck starts working the moment you open a project.

Step 3 — Watch for Highlights

As you write code (or paste AI-generated code), problems get highlighted right in your editor — just like when you misspell a word in a document.

Step 4 — Fix in One Click

See a warning? Hover over it. Most problems have a Quick Fix button that solves it instantly.

Features at a Glance

🔍 Scan Your Code

One click to check your entire project for fake features, broken connections, and security gaps. Think of it as a health checkup for your app.

🛡️ Shield Mode (Agent Firewall)

Watches your code in real-time while AI tools make changes. If an AI agent tries to introduce something broken or dangerous, Shield catches it on the spot.

🚀 Ship Score

Wondering "Is my app ready to go live?" Ship Score gives you a simple answer:

Ship Score: 82/100

✅ All pages connect to real data
✅ Every button has a working action
⚠️ 2 error messages could be more helpful
⚠️ 1 setting is using a placeholder value

Green = You're good to go. Yellow = Worth a quick look. Red = Fix these first.

🩺 Health Check

A quick diagnostic that tells you if your project is set up correctly — missing files, broken connections, outdated settings. Like a doctor's checkup for your codebase.

🎯 Context Engine (Pro)

Maps out your entire project so VibeCheck deeply understands how everything connects. Makes every other scan smarter and more accurate.

🧪 Reality Mode (Pro)

Actually opens your app in a browser and tests if things work — not just if the code looks right. Catches the sneakiest AI mistakes.

✨ Polish (Pro)

Finds rough edges in your app — accessibility issues, inconsistent styling, missing loading states — the details that make the difference between "it works" and "it feels professional."

📐 ISL Studio (Pro)

Describe what you want your app to do in plain English. ISL Studio turns it into a structured blueprint, then generates real, verified code from it.

Works With Every AI Tool

VibeCheck sits alongside whatever AI tool you already use:

✅ Cursor — catches mistakes in AI-generated edits
✅ GitHub Copilot — validates code suggestions before you accept
✅ Claude / ChatGPT — checks code you paste from chat
✅ Windsurf — works seamlessly with Cascade
✅ Any AI tool — if it writes code, VibeCheck can check it

Common Questions

Does VibeCheck slow down my editor? Not at all. Everything runs in the background. You won't notice it's there — until it saves you.

Do I need to create an account? Nope. Install and go. The free features work without any account. You only sign in if you want Pro.

Is my code private? Yes. Your code stays on your computer. Nothing is sent anywhere unless you explicitly use a cloud feature.

I'm new to coding — will this help me? Absolutely. VibeCheck is built for people who use AI to build apps. If you're copying code from ChatGPT or using Cursor to build your project, VibeCheck is your best friend — it tells you when the AI got something wrong, in plain English.

Does it work with my existing project? Yes. Just install the extension and open your project. VibeCheck figures out the rest.
