AI App Rescue & Vibe Code Fixes

Vibe coding gets you to a working demo fast. Getting from demo to a secure, scalable product is where projects stall: authentication that leaks, database rules that were never turned on, a payment flow that works once, a deployment nobody can reproduce. Our AI app rescue service takes over AI-built codebases, fixes the real problems, and leaves you with a system real users can rely on.

Sound familiar?

The situations we get called into

01

It works on my machine, not in production

The demo ran fine locally. Deployed, it throws 500s, environment variables are missing, and nobody can reproduce the build.

02

Every fix breaks something else

You prompt for a fix, the AI rewrites half the file, and a feature that worked last week is gone. The codebase has stopped converging.

03

Auth and permissions are held together with hope

Users can see each other's data, admin checks run in the browser, row-level security was never enabled, and API keys ship to the client.

04

It falls over with real users

Ten users are fine. A hundred is slow. A thousand is an outage: N+1 queries, no indexes, no caching, no rate limits.

05

Payments, emails and webhooks are flaky

Stripe works in test mode, the webhook signature was never verified, emails land in spam, and the retry logic is still a TODO.

06

Nobody can explain the code

The person who prompted it can't maintain it, and the developer you asked for a quote said "rewrite".

We take over projects built with
  • Lovable
  • Cursor
  • Claude Code
  • Bolt.new
  • v0
  • Replit
  • Windsurf
  • GitHub Copilot
  • Base44
  • ChatGPT / Codex
How it works

From first call to handover

  1. 1

    Rescue audit (fixed price)

    We read the whole codebase, run it, and probe the security, data and deployment layers. You get a written report: what's broken, what's risky, what's fine, and a prioritised fix plan with a fixed price for the next phase.

  2. 2

    Stabilise

    Critical bugs, security holes and deployment blockers first. The goal is a version real users can safely use, in weeks rather than months.

  3. 3

    Harden

    Tests around the paths that matter, monitoring and alerts, database integrity, CI/CD, cost controls, and the refactors that make the code maintainable.

  4. 4

    Hand over, or stay on

    Documentation, a walkthrough, and clean repositories in your accounts. Keep building with AI tools with guardrails in place, or keep us on retainer for reviews and the hard parts.

What's included

Codebase and architecture audit with a written findings report
Security hardening: authentication, authorisation, secrets, database access rules
Bug fixing for the issues AI tools keep reintroducing
Production deployment, CI/CD and environments you can reproduce
Database schema, migrations and data-integrity fixes
Performance and cost fixes for slow pages and runaway API bills
Tests and monitoring so regressions are caught before users find them
Handover documentation, or ongoing support if you'd rather we stay
What you get

What you walk away with

A written audit report

Findings, risks and a prioritised plan you can share with co-founders, investors or your board.

FAQ

Questions we get asked

What is a vibe-coded app?+

A vibe-coded app is one built mainly by prompting an AI tool such as Lovable, Cursor, Bolt, v0, Replit or Claude Code, rather than by hand-writing the code. They are fast to build and often genuinely useful. The trouble starts when a demo needs to become a product: security, data integrity, performance and maintainability were never part of the prompts.

Do I need to start over?+

Usually not. Most AI-built apps have a salvageable core. Our audit tells you honestly which parts to keep, which to fix and which, occasionally, to rebuild. A full rewrite is the exception, and we will say so up front if it is the right call.

Which stacks do you work with?+

The stacks AI tools generate most: Next.js and React, Node.js, TypeScript, Python, Supabase and Firebase, PostgreSQL and Stripe, deployed on Vercel or AWS. If your app is built on something else, ask. We will tell you quickly whether we are the right fit.

How much does an AI app rescue cost?+

The rescue audit is a fixed price agreed before we start. The fix phase is quoted from the audit findings, so you are never paying open-ended hours on a problem nobody has scoped. Send us a brief through the proposal form and we will reply with a written scope within three business days.

Will you keep my code confidential?+

Yes. We are happy to sign an NDA before we look at anything, we work in your repositories and cloud accounts wherever possible, and we remove our own access when the engagement ends.

Can I keep using AI tools afterwards?+

Yes, that is the goal. We leave you with tests, CI checks and conventions so the next AI-generated change is caught if it breaks something. Many clients keep prompting features themselves and bring us in for reviews and the hard parts.

My Lovable app stopped working after a change. Can you fix it?+

Yes, and this is the most common call we get. Lovable and Replit projects usually break in the same places: a Supabase migration that half-applied, an environment variable missing in production, an edge function that times out, or a change the AI made to a file it should not have touched. We find the cause rather than prompting around it, fix it, and add the tests that stop it recurring.

Supabase says row level security is disabled in public. Is that serious?+

Yes. That warning means any table it names can be read or written by anyone who has your public API key, which is every visitor to your app. It is the single most common security problem in Lovable and Bolt projects. We enable RLS, write the policies your app actually needs, and test them with a second account before anything else.

Can you move my Lovable, Bolt or Replit app to AWS or Vercel?+

Yes. We export the code into a repository you own, set up a reproducible build, move secrets into proper environment configuration, and deploy to Vercel or AWS with CI/CD. The database usually stays on Supabase or moves to Postgres on AWS, depending on what you need for cost, residency and scale.

Where are you based, and do you work with international clients?+

We are based in Pretoria, South Africa, and work with clients in the UK, the US, Australia and across Africa. Our timezone (SAST, UTC+2) overlaps the full European working day and the US East Coast morning.
