TRIAGE BOARD

Three ways vibe-coded apps quietly bleed revenue

SYM-01most common

Paid, but locked out

Stripe says succeeded. Your customer got the receipt. And your app still won't let them in — because the webhook that tells it “payment happened” was never registered, or fails silently in production.

✓ we fix this — flat rate

SYM-02silent killer

The dead buy button

Checkout opens nothing, errors quietly, or works in test mode and ghosts in live mode. Every visitor who tries to pay just leaves. You can't see it — your revenue can.

✓ we fix this — flat rate

SYM-03compounding

Subscription drift

Charges happen but state doesn't follow: cancelled users keep access, renewals lose it, refunds never sync. Your Stripe dashboard and your database are telling two different stories.

✓ we fix this — flat rate

TREATMENT PROTOCOL

Diagnosed free. Fixed flat. Proven live.

01

Free diagnosis

Describe the symptom below. Within hours you get a plain-English root cause: what broke, why, and exactly what fixing it involves. No call, no strings — the diagnosis is yours even if you fix it yourself.

02

The 48-hour fix

Flat $250 for the broken flow. The clock starts when access is granted — staging first, least-privilege keys only (restricted Stripe keys, collaborator invites — never your passwords).

03

Proof, or it didn't happen

We run a live test purchase through your checkout while recording: money in, webhook delivered, access unlocked. You watch it work. Then a 30-day warranty — if an AI edit re-breaks the same flow, we re-fix free.

WHY TRUST US

No fake counters here.

This corner of the internet is full of “500+ apps fixed!” claims with no names attached — some rescue services even disclaim outcomes in their fine print. We go the other way: every completed fix ends with a recorded live transaction — money in, webhook delivered, access unlocked — and that recording is the deliverable.

We just launched, so the wall below is honest: it fills with real, client-approved recordings as fixes are delivered. Nothing staged. Ever.

BEFORE YOU ASK

Fair questions

?Will you break my app further?

The fix is built and verified on a staging copy first, touching only the named flow. Access is least-privilege: restricted Stripe keys and collaborator invites, never passwords. And the 30-day warranty means the fixed flow staying fixed is our problem, not yours.

?How do I give you access safely?

Stripe restricted keys (you set the permissions), Supabase collaborator invite, repo invite — each revocable by you in one click the moment we're done. We never ask for passwords, and we tell you exactly what to revoke after delivery.

?What if you can't fix it in 48 hours?

You don't pay. The deadline-miss guarantee is automatic — full refund, and you keep the diagnosis. The clock starts when access is granted, not when you pay.

?Why not a $30 Fiverr gig?

Ask a gig for proof the fix works and you get a screenshot and a prayer — some rescue services literally disclaim outcomes in their terms. Here the deliverable is a recording of a live transaction succeeding on your app, a named engineer, and a warranty in writing.

?Do you do security audits?

No — and be wary of paying for one: Lovable, Replit and Aikido now ship security scanning and auto-fixes free or nearly free. Scanners check whether you can be hacked. We check whether your money actually moves. Different problem, and the one costing you revenue today.

?Which platforms and stacks?

Apps built with Lovable, Bolt, Replit, v0, Base44 or similar — typically Supabase + Stripe underneath, deployed on Vercel or Netlify. Hand-coded apps with the same stack are welcome too. Unsure? Send the symptom — the diagnosis is free.

Every hour it stays broken
costs you money.
