Find the security holes in your AI-built SaaS
before your users do.
SaasShield scans your live app like an attacker would — then proves, in plain English, whether customers can read each other's data, fake your Stripe webhooks, or drain your billing. Every finding comes with proof and a fix-ready prompt for your coding agent.
Free scan needs no login and no code access. We only look at what your live app already exposes.
AI writes code fast.
It doesn't write it secure.
The same handful of bugs ship in AI-built apps over and over — because the demo worked, so nobody checked. They don't break anything on launch day. They break weeks later, as a leaked database, a fraudulent charge, or a screenshot on X.
Auth at login isn't enough — every resource needs an ownership check. Miss one and /orders/123 → /orders/124 reads someone else's data.
UUIDs don't fix IDOR. Backend authorization does.
Stripe webhooks that "work" can still trust forged events — that's how a $500 charge hits 175 customers.
Plan limits, coupons, and credits often fail under concurrent requests.
Secrets leaked to your frontend bundle or a public repo are found by bots in minutes.
Most teams never watch for ID probing or cross-tenant access until it's already a breach.
This isn't hypothetical.
It's a weekly news cycle.
Every one of these is a check SaasShield runs.
Lovable — any free account could read any other user's source code, DB credentials, and customer data.
"This is not hacking. This is five API calls from a free account." 48-day exposure.
Lovable, 2026
Moltbook — 1.5M API tokens exposed within 3 days of launch.
Hardcoded Supabase key in the frontend, RLS never enabled. Founder: "I didn't write a single line of code."
Wiz Research, 2026
A Claude Code app shipped its Stripe secret key in config.js.
An attacker found it in DevTools and charged 175 customers $500 each — $87,500.
Reported 2026
Tea — 72,000 images and 1.1M private messages leaked via a public storage bucket.
Including 13,000 government IDs. Federal class actions followed.
Tea app, 2025
of AI-generated code introduces an OWASP Top 10 vulnerability — and that number hasn't improved in two years.
— Veracode
of YC startups on Supabase had data exposed to anonymous access.

AI-assisted commits leak secrets at 2× the rate of human code.

A security check that understands SaaS —
not just websites.
Generic scanners find generic bugs (headers, TLS, old software). SaasShield does that too — for free — but its real job is the SaaS-killing failures generic scanners can't reach, because they need to log in and act like a second customer.
Outside-in scan (free).
Exposed secrets and source maps, missing security headers, leaky CORS, public debug/admin routes, Supabase/Firebase exposure, outdated software.
Inside-out audit (paid).
With test credentials, we crawl your app authenticated and check that every route enforces who's allowed to see what.
Two-account probes (paid — the part nobody else does).
We act as Customer A and Customer B and prove your tenant isolation, Stripe/webhook trust, and billing/credit limits actually hold.
From URL to fixed in four steps.
Scan.
Paste your URL for an instant free read.
Verify & go deep.
Prove you own the domain, add test logins, and run the full audit.
Fix.
Hand each finding's fix-prompt to your coding agent.
Re-test — free.
We re-run the exact probe against your live app and prove the fix actually holds. Then keep checking on every deploy.
What we check.
The free scan tells you what's exposed. The full audit tells you whether you're actually safe.
Not a $9 toy.
Not a $20k pentest.
vs generic / cheap scanners
They read your headers. We log in and prove a customer can't read another customer's data.
vs a full pentest
$5k–$20k and weeks of lead time is overkill before you have real revenue. This is the focused, high-impact layer you need first — same day, self-serve.
vs "just review the code"
Working code can still ship a tenant leak. We test the running app, then prove the fix.
Ship every client app with a security report.
If you build AI apps for clients, “is it secure?” is your liability and your differentiator. Make a SaasShield report part of every handoff — white-labeled, on your portfolio dashboard, re-checked on every deploy.
Start free. Pay when it matters.
No subscription required for the audit. Pay once, get the report the same day.
Instant passive scan — headers, TLS, secrets, CORS, source maps.
One-time full analysis: passive + authenticated + two-account IDOR + Stripe/billing probes. Founder-readable report + fix prompts + one free re-test.
Always-on passive + active monitor. Alerts on new CVEs against your stack.
Everything in Lite, plus authenticated crawl and access-control (authz) checks.
Full deep scan: two-account IDOR/BOLA and Stripe/billing probes on every run.
A clean scan today isn't a clean scan forever.
Your app can sit untouched and still become vulnerable — a new CVE drops for software you already run, or we ship a new check that catches something we couldn't last month. SaasShield keeps re-checking against a threat landscape that moves whether you deploy or not.
Questions we get.
Your AI agent shipped the app.
