Fix an AI-built app · Lovable, Bolt, Replit, Cursor, v0
Fix your Lovable, Bolt or Replit app, and get it ready for real users.
It works in the demo. Before real customers, data or payments go through it, a senior engineer reviews it, and then we finish it at a fixed price.
Photography is illustrative.
- Built with

What we do
It works in the demo. Real users find what the demo skipped.
AI builders are very good at the part you can see. We are a US software engineering firm; finishing the rest is the work.
-
Security and data access
Who can read which records, enforced on the server and in the database.
-
Sign-in and accounts
Sessions checked on the server; password reset and email that work.
-
Payments
Stripe webhooks on the server: paying unlocks access, cancelling removes it.
-
Reliability
Errors reported, jobs that retry, logs that explain failures.
-
Release
Development apart from production, tests before every deploy, a way back.
-
The unfinished features
The part where every new prompt broke something else.
How it works
A scoped review first. Then a fixed-scope completion.
Every step is priced before it starts. You decide after each one whether to go on.
-
A free 20-minute call
You show us the app. We tell you what we expect to find, and whether a review is worth it yet.
-
App Readiness Review, $1,500 flat
A senior engineer reads the code: security, sessions, data access, payments, deployment.
You get Every finding with its severity, root cause and fix, and a fixed quote to finish.
-
Fixed-price completion
Security & Data Hardening from $7,500, or Production Launch from $15,000, in your repository, with tests beside each fix and every change reviewed.
-
Launch and handover
Separate production, a deploy you can roll back, monitoring, and an app you own outright.

Built with
Each AI builder breaks in its own way.
Lovable, Bolt, Replit, v0, Base44, Manus, Cursor, Claude Code, Windsurf and Firebase Studio each leave a different stack and a different set of problems. Pick yours for what usually breaks, what to try first, and how we work on it.
- Lovable →React on Supabase. We test row-level security on every table first.
- Bolt.new →Runs in your browser on WebContainers, with Bolt Cloud or Supabase behind it.
- Replit →Builds and hosts in one place; the published app is a different environment.
- v0 →Next.js on Vercel. Strong screens; the back end is usually the work.
- Base44 →Its own back end and SDK. Most fixes stay on the platform.
- Manus →An agent built the whole project, and nobody has read the code yet.
- Cursor →Your own repository. Usually duplicated logic and missing tests.
- Claude Code →Your own repository. CLAUDE.md, permissions and drift across sessions.
- Windsurf (Devin Desktop) →Now Devin Desktop. Rules and memories need to move into the repository.
- Firebase Studio →Closes 22 March 2027. Move the code, then check the Firestore rules.
Proof
Who does the work, and what they have built.
The founding team has taken a product off an AI app builder before (built, not yet in paid use) and runs a production telehealth platform on Supabase. Across the systems it built and runs:
- 20,900+ automated tests across the systems the founding team built and runs
- 16,800+ CI runs automated builds and test runs on GitHub Actions
- 940+ merged pull requests across the same codebases

Questions buyers ask
Before you send us the app.
Can you work with Lovable, Bolt, Replit, Cursor or v0 apps?
Yes. We work with apps from all five, and with apps built in Claude Code, Windsurf or a mix of tools. Under the tool is ordinary code, usually React or Next.js with Supabase, Postgres or Node behind it, which we write every day. The review needs the repository or an export of it.
How do I get a Lovable app to production?
Connect it to GitHub. Turn on and test row-level security for every Supabase table. Move secret keys out of the browser into server or edge functions. Use a separate Supabase project for production. Add a deploy pipeline that runs tests first, then a custom domain, backups and error monitoring. Do it yourself, or we review the app and do it with you. How we fix Lovable apps.
Is my AI-built app secure?
Nobody can say without looking, including the tool's own scanner. The same problems recur: keys in the browser, sessions never checked on the server, access decided in code the user controls, and database policies missing or too broad. That last one is how CVE-2025-48757 left 170 apps from one AI builder readable without a login in 2025. Our review checks each in your app. The five patterns we find most.
Do I have to start over?
Rarely. Most of what an AI tool produces is worth keeping: the screens, the flows, much of the data model. The review marks each part keep, change or replace, with the reason, before any work is priced.
How long does it take?
The Quick Security Check takes 48 hours and the App Readiness Review 5 business days. Security & Data Hardening usually takes 1 to 2 weeks. The rest of the completion depends on what the review finds, so the plan gives a schedule item by item. Tell us your launch date on the first call and we will say plainly whether it is realistic.
What does it cost?
The first call is free. The Quick Security Check is $495, credited toward the App Readiness Review, which is $1,500 flat and credited toward any fix booked within 30 days. Security & Data Hardening is from $7,500 and Production Launch from $15,000, each at one fixed price set after the review. Ongoing care after launch is from $500 a month, up to $2,000 a month. We never bill hourly on work nobody has sized. The full price list.
Will I own the code?
Yes. The work happens in your repository and hosting accounts from the first day. You keep the code, its full history, and the notes to run it without us.
Can I keep building with Lovable or Cursor after you fix it?
Yes, with one change: an AI tool can quietly undo a fix while building the next feature, so we set up automated checks that every change, yours or the tool's, must pass before production.
