App Rescue

Your AI-built app, made production-ready.

You built 80% with Lovable, Bolt, Replit or Cursor — then hit the wall: auth breaks, Stripe won't go live, the database leaks, deploys fail. The last 20% is the hard part, and it's what we do.

In short

App rescue is taking an app that was largely built with AI tools like Lovable, Bolt, Replit, v0 or Cursor and making it production-ready — fixing the bugs, security, authentication, payments, database and deployment that block launch. FIMM's senior engineers debug and harden AI-generated ("vibe-coded") apps, take them live, and can stay on as your long-term build team.

Who it's for: Founders and teams who shipped a fast AI-built MVP and got stuck on the hard last 20% — the part that has to actually work in production.

What we build

What we build.

A

Bug & error debugging

We track down the runtime errors, broken flows and silent failures that AI tools leave behind, and fix the root cause — not just the symptom.

B

Auth & security

We lock down authentication, sessions, access rules and exposed keys so your app is safe to put in front of real users.

C

Database & Supabase

We fix schema, migrations, row-level security and query performance — on Supabase, Postgres, MySQL or whatever your app runs on.

D

Payments & Stripe

We get Stripe (or your gateway) properly integrated — checkout, webhooks, subscriptions and the edge cases AI-generated code usually misses.

E

API integrations

We wire up the third-party APIs your product depends on, with real error handling, retries and rate-limit safety.

F

Performance

We profile and fix the slow queries, oversized bundles and render bottlenecks that make an AI-built app crawl under load.

G

Deployment

We get you off the prototype host and onto real infrastructure — CI, environments, domains and monitoring — so it stays up.

H

Code review & refactor

We review the AI-generated codebase and refactor the parts that won't scale, so the next feature doesn't break the last one.

How it ships

Scoped, guardrailed, owned.

Automation only earns trust if it's reliable. Here's how we keep it that way.

01

Diagnose

A free 30-minute review of your app and codebase — what's broken, what's risky, what it takes to launch.

02

Stabilize

We fix the blocking bugs and errors first — usually within days — so the app runs reliably.

03

Harden

Auth, security, payments, database and performance brought up to production standard.

04

Ship

We deploy to real infrastructure and hand over a live, monitored app — or keep building with you.

Frequently asked

Common questions.

Can you fix my Lovable app?
Yes. We regularly take Lovable apps that are 80% done and finish the hard part — auth, payments, database, integrations and deployment — then ship them to production. Send us the app and we'll tell you exactly what it needs in a free diagnosis.
My Bolt or Replit app won't deploy — can you help?
Yes. Deployment failures are one of the most common walls with Bolt, Replit and v0 apps. We fix the build, environment and infrastructure issues and get your app live on real hosting with monitoring.
What is vibe coding / an AI-built app?
Vibe coding is building software by prompting AI tools like Lovable, Bolt, Replit, v0 or Cursor instead of writing it by hand. It gets you to a working prototype fast, but the last 20% — security, payments, scale — usually needs real engineers.
Can you add Stripe or Supabase to my app?
Yes. We properly integrate Stripe (checkout, webhooks, subscriptions) and Supabase (schema, auth, row-level security) — the pieces AI-generated code tends to stub out or get subtly wrong.
How long does an app rescue take?
Blocking bugs are usually fixed within days. A full rescue — stabilize, harden and ship to production — typically takes one to three weeks, depending on how much of the app needs rebuilding.
Why not just keep fixing it with AI myself?
AI tools are great at generating code but poor at debugging their own edge cases, security and architecture. A senior team fixes the root cause once, instead of prompting in circles — and stands behind the result in production.
Can you keep building after the rescue?
Yes. Many rescues turn into an ongoing partnership — once your app is stable and live, we can keep shipping features as your long-term development team.
