Lovable, Bolt, v0, Cursor, Replit and Base44 rescue

It looked finished. Then production found it.

We fix AI-built apps with broken payments, missing records, dead webhooks, unreliable auth, and production failures, whichever tool generated them. If it is 2am and a customer just paid for something your app cannot find, start here.

The 48-hour rescue audit

A written diagnosis before another developer starts guessing

You do not need a vague call where someone says the code is bad. You need evidence, a risk order, and a price you can decide against.

Audit price

Free

Written findings in 48 hours

Your first audit costs nothing and the report is yours to keep whether or not you hire us. Only the repair work that follows is quoted, and that price is fixed and agreed before anything is touched.

48-hour written technical report
Critical user-path replay
Architecture and dependency review
Database and data-integrity checks
Authentication and permission checks
Payment and webhook trace
Deployment and environment review
Security and secret-handling findings
Keep, repair, or rebuild recommendation
Fixed quote for the agreed rescue scope

Real failure pattern

The payment succeeds. The product still fails.

Failure 01

Stripe charges the card. No order exists.

The checkout page reports success, but the backend never records the purchase. The user is charged, support has no order, and retrying can create a second charge. We trace checkout, webhook verification, idempotency, database writes, and reconciliation as one path.

Failure 02

The webhook died silently three days ago.

A provider changed an event, a secret expired, or the endpoint began returning 500. Nothing alerted you. Subscriptions, emails, and account access drift out of sync. We add visible failure handling, replay support, logging, and alerts so the same bug does not hide again.

What we inspect

The parts AI builders make easy to start and hard to finish

Lovable, Bolt, and v0 can create a convincing product surface quickly. Production risk usually sits behind that surface.
01

Payments

Checkout state, webhooks, signatures, retries, idempotency, refunds, and database reconciliation.
02

Authentication

Session handling, password flows, OAuth callbacks, protected routes, roles, and admin boundaries.
03

Data integrity

Schema assumptions, missing constraints, duplicate writes, stale state, migrations, and backup paths.
04

Backend behavior

Server actions, APIs, queues, timeouts, third-party failures, validation, and error handling.
05

Production setup

Environment variables, domains, build settings, logs, monitoring, and deployment differences.
06

Security

Exposed secrets, public admin actions, unsafe database access, file uploads, and permission gaps.

Rescue process

From panic to a controlled production plan

01

Send access

Share the repository, live URL, failing path, and relevant service logs through a secure handoff.
02

We reproduce it

We replay the critical user path and follow the evidence through frontend, backend, provider, and database.
03

Get the report

Within 48 hours, you receive written findings, priorities, a salvage decision, and the fixed rescue quote.
04

Repair and prove

If you proceed, we fix in small testable slices, send a Loom every 48 hours, deploy, and monitor the repaired path.

Keep, repair, or rebuild

We tell you which answer the evidence supports

Keep

The architecture is sound. We preserve working code and fix a small number of isolated failures.

Repair

The product is salvageable, but critical flows need deeper backend, data, or security work.

Rebuild

The current path risks customer money or data, and repairing it would cost more than replacing the unsafe core.

If a full rebuild is necessary, the fixed quote includes a production-ready scope, code ownership, working links from day one, two-minute Loom updates every 48 hours, and two weeks of fixes after handover. See how we handled production reliability in the Loopwave case study.

FAQ

Questions founders ask during an app rescue

Can you fix a Lovable, Bolt, or v0 app without rebuilding everything?+
Often, yes. We first separate working parts from unsafe or incomplete parts. The audit tells you what can stay, what needs repair, and what should be rebuilt. We do not recommend a restart just because it is easier for us.
What do I receive in the free audit?+
You receive a written report covering architecture, database behavior, authentication, payments, webhooks, security, deployment, and the critical user path. It includes evidence, priorities, and a fixed quote for the agreed rescue scope.
How much does the audit cost?+
Your first audit is free. We look at the real thing, the live app or the repository rather than a description of it, and send back written findings within 48 hours. You keep the report whether or not you hire us. Only the repair work that follows is quoted, and that quote is fixed before anything is touched.
Can you repair Stripe payments that charge but do not update the app?+
Yes. We trace the complete payment lifecycle: checkout creation, payment intent, webhook signature, event delivery, idempotency, database write, reconciliation, and the state shown to the user.
Will I keep the code after the rescue?+
Yes. You own the code, repository, infrastructure, and accounts. We document the repaired paths and include two weeks of fixes after handover.
How quickly can you start if production is already broken?+
Send the repo, production URL, error details, and access to logs. There is nothing to pay for the audit, so we start as soon as access is complete and deliver the written report within 48 hours.

Stop guessing at the production bug

Send the broken path, repository, and what the customer saw. We will confirm the audit scope and start once access is complete.
