Every new prompt fixes one thing and breaks two others.
Changes reach the live app through version control and a test copy (staging), not straight from a prompt.
You vibe-coded it. Now make it hold up. Safe for real users and real payments.
Lovable, Bolt, Cursor and Replit get an app to a demo fast. We review what the AI wrote, close the holes and keep what works.

A good fit
You have an early product and want to keep it.
- Real users are coming, and you want to keep the prototype rather than start over.
- It runs on React or Next.js with Supabase, Firebase or Node.
- You need someone responsible for security, data and keeping it online from now on.
Not a fit yet
Still validating the idea?
If nobody uses it yet, keep prompting; it is cheaper than a review.
Come back when real users and payments are close.
Not a fit yet
Want a rewrite on day one?
We decide that after reading the code, not before, and we do not keep prompting the same tool for you.
Start with the review; it says when a rewrite is cheaper.
Before real users arrive
The vibe-coded app security checklist
Sixteen checks we run on every AI-built app before it meets real users. Tick what you can confirm today. Your ticks are saved only in your browser.
0 of 16 confirmed
Tick only what you can confirm, not what you assume. Several basics are unconfirmed. That is normal for an AI-built app, and exactly what the system review covers. In good shape. The unticked items are where AI-built apps usually leak data or money. All 16 confirmed. Keep it that way as the app changes.

How we work
Dangerous things first, then what will not cope with growth

01 · Review
What happens
System Review, in About a Week
We read the code, database rules, hosting and connected services, run the checklist for real, and write down what is broken, fragile and fine.

What happens
The Dangerous Things First
Exposed data, leaked keys, missing server checks and unchecked payments come before anything cosmetic. This usually takes days, not weeks.
-
03 · Clean up
What happens
What Will Not Cope with Growth
Business logic moves out of the browser code, and the parts that earn money get automatic tests. We also set up a test copy, backups, error logs and alerts.

04 · Run
What happens
Keep It Running
On a monthly plan the same engineers fix, watch and keep improving it. You keep prompting new ideas; we keep the live app safe.
In production
We build with the same tools, in production
Our own products are written with AI coding agents every day and run with real users and payments, so we know where AI-written code breaks.
FAQ
Questions people ask before a rescue
Rarely. Most vibe-coded apps have a sound shape and a few dangerous gaps. We keep what works and replace what cannot be made safe. If a rewrite would genuinely be cheaper, the review says so, with the numbers.
Apps built with Lovable, Bolt, v0, Replit, Cursor and Claude Code, typically React or Next.js on Supabase, Firebase, Node or Python. When a product has outgrown the tools it started on, we can also move it onto Laravel.
Yes, and you should. We set up a test copy (staging) and a review step. Then prompts can keep adding features without sending a security hole straight to your live app.
Usually within a week. The system review itself takes about five working days, and serious problems are reported the day we find them, not at the end.
If you need one, yes. Either way, we only need read access for the review, and we work in your own code repository and accounts from day one.
