VibeCheck
Free Audit

For AI-built apps

You vibe-coded your app.
Is it ready for real users?

Vibe coding helped you move fast. We help you find the security, reliability, configuration, and production issues that matter once real users, payments, and customer data enter the picture.

Free external scan • No GitHub access required • Safe, non-destructive checks

No credentials required

The free audit only needs the public URL of your application.

Non-destructive

The external scan does not exploit vulnerabilities or modify application data.

Transparent findings

Every result explains what was observed, why it matters, and how confident the scanner is.

Analyzing production readiness…0%

Preview of the audit experience. Your scan runs against your live URL.

Your MVP became a real product. The engineering requirements changed.

AI-assisted tools are excellent for speed, experimentation, and getting to product-market signal. That part worked — you have something real.

But once the application starts handling:

  • user accounts
  • customer data
  • payments
  • external APIs
  • production traffic
  • business-critical workflows

the standard changes.

You don't need to stop vibe coding. You need a production safety net.

What happens after you click Scan?

1

We inspect the public application

We check safe, externally observable production behavior — the same things any visitor's browser can already see.

2

You get a readiness report

See security, reliability, configuration, performance, and other findings — each with evidence and a confidence level.

3

You decide what happens next

Fix issues yourself, connect GitHub for a deeper audit, or ask our engineers to help.

Know what you're shipping before your users find out.

Every scan produces a readiness score, category breakdowns, and prioritized findings — each labeled by severity and by how confident we are in it.

Example

Production Readiness

1 High 2 Medium 1 Low 1 Info
Security58/100
Reliability67/100
Performance74/100
Configuration61/100
Privacy71/100
HighConfirmed

Content Security Policy is not configured

Observed
Responses did not include a Content-Security-Policy header.
Impact
CSP is the main browser defense against injected scripts — without it, one XSS bug exposes user sessions.
Recommended action
Add a CSP in report-only mode first, then enforce it.
MediumConfirmed

Production source maps are publicly accessible

Observed
A production JavaScript source map returned HTTP 200.
Impact
Source maps let anyone reconstruct your original source code.
Recommended action
Disable source map output in production builds.
MediumConfirmed

Several frontend requests return 404 responses

Observed
Three resources referenced by the page failed to load.
Impact
Broken assets degrade the UI and hint at stale references.
Recommended action
Remove or fix the failing references in your build.
LowConfirmed

Referrer Policy is not explicitly configured

Observed
Responses did not include a Referrer-Policy header.
Impact
Full URLs may leak to third-party sites users click through to.
Recommended action
Add Referrer-Policy: strict-origin-when-cross-origin.
InformationalStrong signal

Application appears to use Supabase authentication

Observed
Client code communicates with a Supabase authentication endpoint.
Impact
Not an issue — an inventory note about your dependency surface.
Recommended action
No action needed unless this is unexpected.

How we report

No scare tactics.

A missing header is not the same thing as a breached database. Our reports separate confirmed findings, strong signals, and issues that require code-level verification.

If we can't verify something externally, we'll say so.

What the free audit actually checks

Safe, externally observable checks — not a penetration test, and we'll never pretend otherwise.

Security Configuration

  • HTTPS configuration
  • Security headers
  • Production error exposure
  • Publicly accessible debug information
  • Exposed source maps
  • Unsafe frontend configuration
  • Public exposure of sensitive artifacts

Reliability

  • Failed page resources
  • Broken requests
  • Server errors
  • Redirect problems
  • Obvious runtime failures
  • Malformed responses

Production Configuration

  • Deployment behavior
  • Cache behavior
  • Production headers
  • Development artifacts
  • Public metadata
  • Environment-related exposure

Performance

  • Response latency
  • Asset size
  • Obvious rendering bottlenecks
  • Unnecessary frontend resources
  • Basic page performance signals

Third-Party Services

  • Authentication providers
  • Analytics
  • Payment providers
  • Monitoring
  • Externally loaded services

What we don't do

  • We don't brute-force accounts.
  • We don't bypass authentication.
  • We don't attempt privilege escalation.
  • We don't modify application data.
  • We don't run denial-of-service tests.
  • We don't attempt to exploit detected vulnerabilities.
  • We don't access private repositories without explicit authorization.

The free scan is designed to be safe for production applications.

Built with AI? You're in the right place.

Works with apps built using tools like:

LovableCursorReplitBoltv0Claude CodeChatGPTGitHub CopilotWindsurfSupabaseFirebaseNext.js

If it's a web app live at a URL, we can scan it — whatever built it.

This is probably for you if…

“I'm about to launch.”

You got the app working and want to know whether there are obvious production issues before promoting it.

“I added Stripe.”

Payments are now involved and you want someone to sanity-check the production setup.

“Users are signing up.”

The project is no longer just a prototype and you're starting to worry about data, permissions, and reliability.

“Every change breaks something.”

The AI-generated codebase is becoming difficult to reason about.

“A customer asked if we're secure.”

You need a clearer picture of how your application is actually configured.

“I need a real engineer now.”

You don't want to rebuild the product. You want someone to stabilize and productionize what already works.

Probably not the right fit if…

  • you're only experimenting with a throwaway prototype
  • the app is not accessible online yet
  • you want offensive penetration testing
  • you don't control or have authorization to test the application
  • you're looking for a generic website design service

Level two

Want the code reviewed too?

The external scan can only see what's visible from the public application. For a code-level review of authorization, database access, secrets, and payments, talk to one of our engineers.

A real engineer reviews the code with you — no rebuild required.

A code-level review can inspect

  • Authentication logic
  • Authorization
  • Database access
  • Supabase RLS
  • Secrets handling
  • Server/client boundaries
  • API validation
  • Payment logic
  • Webhook verification
  • Dependencies
  • Technical debt
  • Test coverage

How we handle your data

✓

URL scans

The scanner processes publicly accessible application data required to generate the report — nothing more.

✓

Sensitive values

If potential secrets are identified, reports redact values rather than display them in full. We never store full secret values unnecessarily.

✓

GitHub

Repository access only occurs after your explicit authorization, is read-only, and is limited to the repository you select.

✓

Retention

Report links are access-tokenized. Retention policies are published on our security page as they are implemented.
