NO SECURITY DEGREE REQUIREDBuilt for vibe coders —
Built for vibe coders —
not security experts.
You shouldn’t need to understand OWASP, CSP headers, row-level security, or authentication flows to launch a good product. Snytchr translates technical risks into clear, actionable fixes you can paste straight back into Lovable, Cursor, Bolt, or your AI builder.
WHY THIS MATTERSAI builders ship the feature.
AI builders ship the feature.
Not always the safeguards.
Your app can look finished and still leave the basics undone. These are the gaps we see most in vibe-coded apps — and exactly what Snytchr checks for.
Your database can be wide open
AI builders often scaffold your database without enabling row-level security, leaving customer data readable through your public app.
Secret keys ship to the browser
“Put your key here” often means the client bundle — so anyone who opens your app can copy a key meant to stay on your server.
Nothing slows down abuse
Without rate limiting, your login, sign-up, and AI endpoints can be brute-forced, spammed, or run up into a surprise bill.
A URL change reaches other users
Without server-side access checks, changing an ID in the URL can surface admin pages or someone else's records.

The things people ask most about running Snytchr. The rest are on the full FAQ.
What is Snytchr?
Snytchr is a launch-readiness scanner for apps built with AI tools. Paste your app's URL and it probes the app the way an attacker would, then gives you a plain-English verdict — safe to launch or not — a 0–100 readiness score, and the exact fix for anything it finds. One URL in, a launch decision out.
What's a “vibe-coded” app, and do I need to be technical?
Vibe-coded apps are the ones you build by describing what you want to an AI builder — Lovable, Bolt, v0, Cursor, and the like. Snytchr is written for exactly that audience: every result is in plain English with a copy-paste fix, so you don't need a security background to understand it or act on it.
Which builders and platforms does Snytchr support?
Snytchr is tuned for apps shipped with Lovable, Bolt, v0, Cursor, Claude, ChatGPT, Replit, Windsurf, Base44, Rork, Emergent, and IndigiCoder, and for Supabase and Firebase backends. But it works on any deployed web app — if it has a URL, Snytchr can scan it.
Is it safe to run on my live or production app?
Yes. The free scan is read-only — it only looks at what your app already shows any visitor, and its probes test whether a door is open without walking through it. Nothing is changed, created, or deleted. See how we scan safely →
What does Snytchr actually check?
Snytchr checks authentication, authorization, secrets, databases, APIs, AI endpoints, infrastructure, abuse protection, and dozens of other production risks. See the full list on What we scan.
How much does Snytchr cost?
Scanning and your verdict are always free. Unlock the full report and exact fixes for $29. To keep shipping, Continuous is $39/month (monitoring plus 20 credits) and Studio is $149/month (multiple apps, Auto-Fix, and 80 credits). See pricing for the details.
