Your vibe-coded app is one deploy away from breaking.
Most AI-generated code looks fine in development.
It explodes in production.
Don’t wait days for human testers to find your bugs. Get an instant, senior-level audit in seconds.
One-click GitHub connect → deep static + Gemini 3.1 Pro semantic analysis → exact Quick Fix patches.
Human testers find UI glitches after you deploy.
VibeCheck finds the silent architecture bombs that actually take down your app before you deploy.
Why not just use Claude?
Generic LLMs give you inconsistent, shallow feedback that misses the exact failure modes killing indie apps. They don’t know your full codebase context.
Why not human QA testers?
They take days, cost hundreds, and only find superficial UI bugs. They can’t see the unhandled promise rejections about to crash your server.
“Can’t I just use Claude or pay a human QA tester?”
Yes. You can.
You’ll get 800 words of polite, hand-wavy suggestions that sound smart but miss the real landmines:
- Test-mode backdoors left in production
- Silent
console.errorthat returns nothing to the user - Webhook endpoints that charge customers twice on retry
- God components,
anyabuse, missing error boundaries, stack trace leakage…
Generic LLMs give you hand-wavy advice. Human QA testers take 3 days just to tell you the checkout button is hard to read.
Neither of them are good at finding the exact ways your code will quietly destroy itself in production.
VibeCheck is not a chat box or a slow manual service.
It’s an automated, specialized scanner trained to catch the exact failure bombs currently shipping with every vibe-coded Next.js app.
You get:
- Consistent, severity-ranked results
- Real, copy-pasteable Quick Fix patches
- Brutal honesty instead of polite hedging
Most solo founders who ship real apps end up paying for this kind of clarity eventually — usually after their first production incident.
You can pay for it before it happens.
How it works
From messy vibe-code to a rock-solid production foundation in three steps.
1. Connect GitHub
Log in with one click. We request read-only access to clone your repository safely into a completely ephemeral local sandbox.
2. Include your key
You securely provide your Gemini 3.1 Pro API key, and our engine orchestrates the context gathering and brutal semantic analysis.
3. Get brutal audits
Review a severely ranked list of silent failure bombs, memory leaks, and get copy-pasteable Quick Fix patches instantly.
Your code stays 100% private and temporary.
- We only perform a shallow clone of your repo for the duration of the scan
- Your code is never stored on our servers
- The clone is automatically deleted immediately after the scan finishes
- We only request the minimum GitHub permissions needed (read-only)
Many developers already trust tools like Cursor, Claude Projects, and GitHub Copilot with their private repos.
VibeCheck follows the same high-security standard.
Pay once. Scan forever.
No watered-down models. No surprise bills.
