Prodable’s free scanner runs about 48 look-only checks on your live v0 app — leaked secret keys, missing safety settings, open doors to other sites, weak email and domain protection. No signup, results in about a minute. v0 has the strongest built-in safety checks of any AI builder; a look-only check from the outside shows what really went live.
Paste your v0 or Vercel URL — the scan works on any live app.
Credit where it’s due: v0 has blocked more than 17,000 unsafe deploys. That is real protection, and it’s genuinely ahead of the field. We’re not here to scare you about v0 — its defaults are among the best you can build on.
But those checks happen while v0 builds your app. They don’t check what’s live after you plug in a database, add secret keys, drop in outside code, or tweak things by hand. The bigger picture is a reminder to check rather than assume: Veracode found 45% of AI-generated code fails security tests — including code from strong tools, once people and add-ons enter the picture.
Prodable checks the live app from the outside — the view an attacker actually has. We look for leaked keys, missing safety settings, open doors to other sites, and weak email and domain protection, across about 48 checks. It’s not a competitor to v0’s built-in checks; it’s the independent proof that they held all the way to your live app.
Built-in checks describe what the platform tried to prevent. Prodable shows what your live app actually exposes — independently, from the outside.
Leaked keys and passwords
We read the code your app ships to the browser, rebuild any hidden code left exposed, and find leaked keys (Stripe, OpenAI, Supabase), password files, and hidden project files that made it into your live app.
Open doors and weak settings
We check for missing browser protections and whether other websites can act as your logged-in users — the gaps that survive a clean build once you add integrations.
Email and domain safety
We check the settings that stop scammers spoofing your domain (SPF, DMARC, and more) — basics that built-in checks never touch and AI-built sites almost always skip.
We run about 48 safe, look-only checks on your live site and give you a grade from A+ to F. We only read what's already public — we never log in, change, or delete anything.
v0 gives you a strong starting point — it has blocked over 17,000 insecure deploys. But a guardrail at build time isn't verification of what shipped once you add a database, secrets, and custom code. Prodable's free scan runs ~48 read-only checks against your live v0 URL and returns an A+ to F grade so you can confirm rather than assume.
It blocks a lot of them — 17,000+ and counting — and that's real protection. But guardrails act on the code v0 generates, not on the exposures introduced by integrations, environment variables, or manual edits after generation. An external scan sees the finished, deployed app the way an attacker would.
The state of the live deployment: secrets that ended up in the shipped bundle, missing or misconfigured security headers, open CORS, and DNS/email hygiene like SPF and DMARC. These are properties of what's actually running at your URL, which is exactly what a read-only external scan measures.
Yes, and it always will be. For Prodable the free scan is the funnel, not the product — it's how we find what to watch. There's no signup, the verdict is never gated, and the scan is read-only.
Free, no signup, results in about a minute. You see your full grade with no email — the scan is free because fixing what it finds is where we come in.
