The evidence

Vibe Coding has a security problem.

These aren't our numbers. They're from cybersecurity researchers.

45%

of AI code contains security flaws

Veracode tested 100+ LLMs on 80 development tasks. Result: nearly 1 in 2 AI-generated code samples introduces vulnerabilities. Java reaches a 70% failure rate.

AI writes code that works. Not code that's safe.

Cursor, Copilot, Claude, Lovable, Bolt — these tools generate code fast. But 45% of that code contains critical flaws.

What AI does silently
  • API keys (OpenAI, Stripe, Supabase) hardcoded in frontend code
  • SQL injections — AI concatenates your inputs directly into queries
  • XSS flaws everywhere — innerHTML, no sanitization, open DOM
  • Auth logic backwards — a real case blocked logged-in users and let anonymous ones in
  • Databases accessible without auth from the outside
What Fyneex catches for you
  • Every flaw detected with a copy-paste fix
  • Exposed secrets scan — API keys, tokens, credentials
  • Clear report even if you're not a developer
  • Fix Plans auto-generated by AI
  • Continuous monitoring — alerts before it breaks in prod

AI reviews your code? It misses the important stuff.

Ask ChatGPT or Copilot to review this code. They'll say it's fine. Fyneex finds what they miss.

How does it work, concretely?

A process designed so your code never leaves your control.

1

Secure upload

Your code is transferred via a TLS 1.3 encrypted channel. Only our analysis engine accesses it.

Sécurisé
2

In-memory analysis

The AI analyzes your code directly in RAM. Nothing is written to disk, no copy is kept.

Sécurisé
3

Report + deletion

You receive your detailed report. The source code is purged immediately and permanently.

Sécurisé

They vibe. Without the fear.

Vibe coders and devs who sleep better since using Fyneex.

I shipped my SaaS in 2 weeks with Cursor. First Fyneex scan: 3 API keys hardcoded in the frontend and a SQL injection. Could have drained my Stripe account.

I'm not a dev, I vibe code everything with AI. Fyneex found flaws I didn't even know existed. The Fix Plan told me exactly what to copy-paste to fix it.

We use Copilot and Claude for everything. Fyneex runs before every deploy. It already blocked 2 deployments with critical flaws none of us had caught.

Frequently asked questions

What is Fyneex exactly?

Fyneex is an automated code audit tool, built specifically for AI-generated code (Cursor, Copilot, Claude, Bolt, Lovable...). It scans your code in 5 phases — security, performance, quality, optimization, infrastructure — and generates a report with ready-to-apply fixes.

Which languages does it support?

Fyneex supports JavaScript, TypeScript, Python, Go, PHP, Ruby and more. Regardless of the framework or AI tool used.

I'm not a developer, is this for me?

Absolutely. Vibe Coder mode translates everything into plain language. You understand the problems and get Fix Plans to copy-paste directly into your favorite AI tool.

Is my code safe with you?

Your code is analyzed in RAM and deleted immediately after the audit. Nothing is written to disk. TLS 1.3 encryption, EU infrastructure, zero human access.

What is a Fix Plan?

A Fix Plan is an auto-generated correction plan. It gives you the exact code to modify or add to fix each flaw. You can copy-paste it directly into Cursor, Copilot or any other tool.

Can I use Fyneex for free?

Yes! The free plan includes 1 free audit. Perfect for scanning your project before going live. No credit card required.

You can't review code you don't understand. But Fyneex can.

45% of AI code contains flaws. A scan takes 5 minutes. Your first audit is free.
