Break your app
before your users do.

Synthetic users through your AI-built product. We try to break its auth, get stuck in its UX, and find what leaks — then send you a prioritized list before it becomes someone else's problem.

$ production-audit --app piedpiper-v2 --report
[CRITICAL] User can self-promote to paid plan without Stripe→ POST /api/user/plan with {"plan": "pro"} — no payment validation→ Plan change persisted to DB; Stripe webhook never checked→ Risk: any authenticated user gets Pro features for free
[HIGH] Trial expiry enforced in UI only, not in API→ Frontend hides paid features after trial — API still responds→ Endpoints /api/export and /api/analytics open to expired accounts→ Risk: users never upgrade; revenue leaks silently
[HIGH] Onboarding gate is client-side only→ Step 3 completion stored in localStorage, not server state→ Navigating directly to /dashboard skips required setup→ Observed: incomplete accounts reach broken state with no recovery path
[MEDIUM] File uploads stored in public S3 bucket→ User files accessible without auth via predictable URL pattern→ Pattern: /uploads/{user_id}/{filename} — enumerable by user ID→ Risk: any user's private files readable by anyone with the link
[MEDIUM] Empty state has no path forward for new users→ 4 of 5 synthetic sessions stalled on blank dashboard within 30s→ Primary CTA (Create project) only in sidebar — invisible on mobile→ No inline prompt, no sample data, no guided action
5 findings  CRITICAL: 1  HIGH: 2  MEDIUM: 2

Early access is intentionally limited while we scale the infrastructure behind the platform. We're inviting 5 apps per batch to keep runs reliable and review quality high.

FAQ

Claude's built-in security features help you write safer code as you build. This is different: we test your already-shipped app from the outside, the same way a real user — or an attacker — would. We're not reviewing code. We're probing behavior: what can a logged-in user actually do, what paywalls hold, where onboarding breaks. It's behavioral testing, not code review.

An AI agent built for a specific product mission — for example: 'sign up as a free user and try to get Pro features without paying.' Our engineers design each synthetic user around your app's actual flows, so it explores privilege escalation, payment gates, and onboarding paths in a way that's specific to you, not generic. It never looks at your code — only what a real customer would see.

A prioritized report. Each finding includes: a severity level (CRITICAL / HIGH / MEDIUM), a reproduction path so you can verify it yourself, the business risk in plain language, and a suggested fix. No fluff — just what you need to act.

Founders and small teams who've shipped an AI-built or vibe-coded app and want to catch problems before customers do. Especially useful before a Product Hunt launch, a funding round, or a scaling push — when the cost of a broken auth or a revenue leak is highest.

A staging or production URL and access credentials (a test account works fine). No codebase access, no repo permissions, no infra access. We work from the outside in.

The ASAP human audit delivers within 5 business days from the day we confirm your slot. The platform (coming soon) is designed to return results in hours.

Great news — and still useful. A clean report you can share with investors or enterprise customers is worth something. We'll still surface any UX friction we observe in synthetic sessions, so you'll get at least a handful of actionable notes.

No. We only access what a normal user would see through the UI and API. No codebase review, no data export, no third-party sharing. Test account credentials are deleted after the audit completes.
