Before real users find
the weak spots,
we do.

$ 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

When companies bring us in

Before launch

You're about to put the product in front of paying users. An independent set of eyes on the flows that cannot fail.

Before scale

You're increasing traffic, acquisition or customer volume. Behavior that was acceptable at 100 users becomes critical at 10,000.

After rapid AI-assisted development

The product changed faster than your QA confidence. A verification pass before the next growth push.

What we protect

We focus on the flows tied to revenue, access and customer trust.

Revenue

  • —Checkout flows
  • —Subscription states
  • —Plan upgrades & downgrades
  • —Billing edge cases
  • —Trial and paywall integrity

Access

  • —Authentication paths
  • —Authorization and permissions
  • —Invitation flows
  • —Role escalation
  • —Session handling

Customer journey

  • —Onboarding completion
  • —First value moment
  • —Critical workflow integrity
  • —Account recovery
  • —Error and edge-state handling

No scores without evidence

Every finding includes reproduction steps, business impact and a proposed fix.

Finding #01HIGH RISKVERIFIED

Observed

A user on the free tier can reach an unintended billing state by interrupting a checkout flow mid-session and replaying the confirmation URL.

Business impact

Revenue loss per occurrence. If discovered and shared, could be exploited at scale before detection.

Evidence

Session replay · 01:42–02:11 Network trace · 3 affected requests Reproduced on: production

Next action

Validate billing state server-side on every confirmation. Do not rely on client session continuity for payment intent resolution.

Engagement process

01

Scope

15–30 min kickoff call. We identify which flows carry the highest blast radius — the ones tied to revenue, access or your core user promise.

02

Independent testing

We approach the product from the outside, the same way your users — and someone trying to exploit it — would. No codebase access. Behavioral, not structural.

03

Senior review

Findings are deduplicated, prioritized and verified by a human engineer before anything is written into the report. No raw output, no noise.

04

Executive debrief

60 minutes with the founder or CTO. We walk through every finding, explain severity and answer questions about remediation.

05

Re-test

After you apply fixes, we confirm the critical findings are resolved. Included in scope.

Every review is signed off by a senior engineer

What this is

An independent assessment of whether your product's highest-risk user journeys behave as intended — in the real application, from the outside, before they become someone else's discovery.

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.
