01 — The state of vibe-coded software

The tools that ship our code doubled in a year.
The tools that check our code did not.

02 — How it works

Three moves. One report.

01
Paste or connect

Drop in a file, paste a snippet, or hook up a GitHub repo. We chunk anything over 30k chars and keep context across files.

02
The Engine runs

VibeScan™ — a proprietary detection prompt — walks your code through five layers of AI-specific failure modes that Snyk and Semgrep skip.

03
Report in 30s

Severity, exploit path, evidence, fix. Every finding is shareable, every fix is one PR away. Ship_ready: false until critical findings clear.

03 — Live demo

An AI-generated checkout endpoint.
Three real vulnerabilities.

142 lines of the kind of code Cursor and Copilot ship every day. Findings, severity triage, coverage matrix, exploit paths, and ready-to-merge fixes — real output from the VibeScan™ Engine.

// app/api/checkout/route.tsimport { stripe } from '@/lib/stripe';import { supabase } from '@/lib/supabase'; export async function POST(req: Request) {  const { priceId, userId } = await req.json();   const { data: user } = await supabase    .from('users')    .select('*')    .eq('id', userId)    .single();   const session = await stripe.checkout.sessions.create({    line_items: [{ price: priceId, quantity: 1 }],    mode: 'subscription',    customer_email: user.email,    success_url: `${req.headers.get('referer')}?ok=true`,    metadata: { userId },  });   return Response.json({ url: session.url });}
Findings · 3

userId is taken directly from the request body, never compared to the authenticated session user.

const { priceId, userId } = await req.json();
const { data: user } = await supabase
  .from('users').select('*').eq('id', userId).single();
Exploit path

1. Attacker signs up. 2. Captures any other user's id. 3. POSTs { priceId, userId: victimId } — victim's email is sent to Stripe, victim's card is charged.

Fix

Drop userId from body. Read from session: const { data: { user } } = await supabase.auth.getUser();

04 — Built for AI code, not legacy code

Legacy scanners were built for human-written code.
They miss what AI ships.

“Caught an IDOR Snyk had been quiet about for six months. Twelve seconds.”
Lead engineer · Series A fintech
“Our entire stack is Cursor-generated. VibeCheck is the first scanner that knows that.”
CTO · YC W26 batch
