Why AI-Built Apps Stall Before Launch

Lovable, Bolt and v0 are brilliant at the first 80%. The last 20% — security, payments, real users — is where prototypes stall. Here's what we see in almost every triage, and how we fix it:
Call Icon

Challenge

Stripe works in the demo, then fails on real cards.

Solution

We move keys server-side, recreate the product catalogue in live mode and register signature-verified webhooks — then test with a real charge and a real refund.
Call Icon

Challenge

Supabase tables with Row Level Security off — your data is one public anon key away from anyone.

Solution

We write RLS policies that match your product's actual rules, test them from a second account, and rotate any keys that were exposed.
Call Icon

Challenge

Auth that loops, redirects to localhost, or never expires a session.

Solution

We fix the full auth surface — OAuth config, Site URLs, password resets, session expiry — and test every path against the production domain.
Call Icon

Challenge

Features the AI left half-finished when the tokens or the patience ran out.

Solution

Senior engineers finish the remaining 20% by hand — usually faster than more prompting — and harden it on the way through.
Call Icon

Challenge

No monitoring, so your users find the bugs before you do.

Solution

Error tracking, structured logs and uptime alerts wired in, plus a deploy pipeline so shipping the next fix isn't scary.

"The service that Fuselio has offered us has been amazing.

After some years of trying to develop an app for our medical diagnostics company in Mexico they were able to help us bring the app to life. Their service has been great.

Our time zone differences has been a challenge but they where very flexible with us and the communication channels used where very efficient. The best thing about the service was the response time, the disposition and the help when developing the APIs."

FAQ

FAQs on AI App Rescue

Do you rewrite the app from scratch?

Almost never. Lovable and Bolt generate real React and Supabase code with good bones. We audit it, keep what works, and fix what's broken — a rewrite is the last resort, and the triage report says so honestly if it's needed.

Which platforms do you rescue?

Lovable, Bolt.new, v0, Replit, FlutterFlow, and codebases built with Cursor or Claude Code. If an AI wrote most of it and it almost works, it's in scope.

How fast can you start?

Triage starts within a business day of repo access and the report lands within 48 hours. Most fix sprints run one to two weeks.

Can I keep building while you fix?

During the security pass we ask for a short freeze on schema and auth changes; after that you can keep prompting features in parallel and we flag conflicts in the shared repo.

Can you add new features too, not just fix?

Yes. Once the foundation is safe, feature work is normal product development — quoted the same fixed-price way, often inside the same sprint.

Do you need my Supabase and Vercel accounts?

Read access for triage, scoped access for the fix. We work least-privilege, you rotate keys after handover, and everything stays in your accounts.

Which stacks do you cover?

React and Next.js frontends with Supabase/Postgres backends — what these tools generate — plus Vercel or Netlify hosting, Stripe billing and the usual API integrations.

What if the app can't be saved?

Then the triage says exactly that, with what a correct build would cost instead. A $299 honest answer beats a $50,000 slow one.
