You built the app in a weekend. Customers are signing up. And somewhere in the back of your mind is the question of whether the thing is actually safe.
Vibe Coding Cleanup in 6 Steps
- 1
Get the code into a repository you own
Export or sync the project to a GitHub repository in your company's account before anything else. Every fix, review and rollback depends on it.
- 2
Audit before anyone changes anything
A written list of what is wrong, ranked by risk, from someone who has read the code. Not a quote for a rebuild.
- 3
Fix data access first
Database access rules, exposed keys and server-side permission checks. These are the problems that leak customer data.
- 4
Fix money second
Payment webhooks, subscription states and anything that decides who has paid for what.
- 5
Add what the builder skipped
Separate test and production environments, backups, error monitoring and tests on the paths customers use most.
- 6
Decide who keeps it running
The app will keep needing changes. Decide now whether that is you and the AI tool, a developer, or both, and agree on one source of truth for the code.

AI app builders are genuinely good at getting a product in front of customers. They are much less good at the parts customers never see: who can read which row of the database, which keys are safe in a browser, what happens when a payment fails. Those are the parts that matter once real people and real money are involved.
This guide is for founders who built a product with Lovable, Bolt, Replit, Cursor or a similar tool, have early customers or are about to, and want to know what needs fixing and who should fix it.
What Is Vibe Coding Cleanup?
The term vibe coding was coined by Andrej Karpathy in February 2025 for building software by describing what you want to an AI and accepting what it writes, without reading much of the code. It spread fast enough that Collins Dictionary named it its word of the year for 2025.
Vibe coding cleanup is what comes after: auditing that code, fixing what is unsafe or broken, and adding what a production app needs. You will also see it called a vibe code audit, an AI code audit or an AI-generated code review. The audit is the diagnosis. The cleanup is the treatment.
Why AI-Built Apps Need Cleanup
This is not a theoretical worry. Three pieces of research point the same way.
Veracode's 2025 GenAI Code Security Report tested more than 100 language models on more than 80 coding tasks and found security flaws in about 45 percent of the samples, with newer and larger models doing no better than smaller ones. Its spring 2026 update found pass rates still stuck around 55 percent.
The Lovable case shows how this plays out in a real product. A researcher scanned 1,645 Lovable projects and found 170 with databases exposed through missing or misconfigured row level security. It was recorded as CVE-2025-48757 with a critical score of 9.3. Lovable disputes the CVE, on the grounds that each customer is responsible for protecting their own application's data. Both things can be true, and the second is the reason to audit: the platform will not check your configuration for you.
Escape, a security company, scanned about 5,600 publicly available vibe-coded apps in 2025 and found more than 2,000 vulnerabilities, more than 400 exposed secrets such as API keys, and 175 instances of exposed personal data. It describes those numbers as a conservative baseline, because its scan was passive.
What a Vibe Code Audit Usually Finds
Most AI-built apps fail in the same handful of places. You can use this as your audit checklist, or as the scope you hand a developer.
The vibe code audit checklist
- Row level security is on for every table in the database, with policies that only let each user read and change their own rows. A table with it off, or with a catch-all policy, can be read and written by anyone holding the app's public key.
- No secret keys in the browser. Only publishable keys belong in front-end code. Service keys, Stripe secret keys and third-party API keys live on the server.
- Payment webhooks are verified. Stripe's docs describe checking the Stripe-Signature header against your endpoint secret, so a forged request cannot mark someone as paid.
- Permissions are checked on the server, not just hidden in the interface. Hiding an admin button does not stop someone calling the admin action directly.
- Separate test and production environments, so experiments do not touch customer data.
- Backups you have actually restored once, and error monitoring that tells you when something breaks before a customer does.
- Tests on the paths that matter most: sign up, log in, pay, and the one action customers use every day.
- The code, the database, the domain and every service account belong to your company, not to a personal login.
Check Your Own App First
You do not need to read code to find the worst problems. An hour on these checks will tell you how urgent the cleanup is.
Make a second account and try to see the first account's data. Change an ID in the address bar, or open a page that belongs to the other user. If you can see it, your access rules are broken, and that is the first thing to fix.
Look at your database settings. If your app uses Supabase, open each table and check that row level security is enabled and that the policies mention the signed-in user. A policy that simply allows everything is the same as having none.
Search the code for keys. Look in the exported repository for anything named secret, service role or sk_live. If it is in a file that runs in the browser, treat the key as leaked: rotate it, then move it to the server.
Write down what you do not understand. Every feature you could not explain to a new developer is a place a bug can hide. That list becomes the start of the audit.
Fix or Rebuild?
The most expensive mistake in a cleanup is a rebuild nobody needed.
The usual case. Access rules, key handling, webhook verification and tests can all be added to the code you have, and customers keep using the app while it happens.
Replace that piece behind the same screens and keep the rest. Slower than a fix, far cheaper than starting over.
Rare, and only after an audit says so. Keep the old app running until the new one has every feature customers actually use.
WitsCode, which sells developer help for Lovable apps, warns that a common failure is a developer deciding to rewrite the whole app, and recommends putting the scope in writing so the work is a fix rather than a rebuild. It is good advice. A developer who wants to start over before reading the code is telling you about their preferences, not about your app.
What Vibe Coding Cleanup Costs
Few providers publish prices, so treat any figure as a starting point for quotes.
Forasoft, an agency that sells this work, estimates a focused security audit at about $3,000 to $10,000 and hardening a broken app at about $15,000 to $45,000. RapidDev cites freelancers at $50 to $150 an hour, or $5,000 to $15,000 for a project. Chudovo describes a typical cleanup as 2 to 4 weeks, after a free assessment. All three sell the service, so get two or three quotes against the same written scope.
The cost nobody quotes is what happens after. A cleaned-up app with paying customers does not stop needing work. Customers ask for features, integrations change, and every new change made by prompting the AI tool can quietly undo a fix. Budget for the cleanup and for who keeps the app healthy afterwards.
Need a developer for your AI-built app?
A senior developer on subscription: $849 a month, as many requests as you like, each shipped within 2 to 3 business days, and your money back if the first 7 days don’t prove it.
One-Off Cleanup or an Ongoing Developer?
A fixed scope and a fixed price. Make sure the handover includes documentation and the rules you should follow so new prompts do not undo the fixes.
The audit becomes the first request and each fix ships on its own, followed by the features customers ask for. Pause when it is quiet.
The right move once the app is the business and you can keep someone busy all year. Our guide to hiring a software developer covers when you are ready.
Vibe Coding Cleanup With StackTie
We run a product development subscription, so read this with that in mind.
It fits the founder whose AI-built app is live and growing. Your first request can be the audit: a ranked, written list of what is wrong. Each fix then ships as its own request, worked one at a time by a senior developer in your existing codebase, followed by whatever your customers ask for next. The code stays in your repository from the first commit, and the homepage has the price, the turnaround and the guarantee.
It is not a penetration test or a compliance certification. If you need a formal security assessment for an enterprise customer or a regulated industry, use a specialist security firm, and use us for the fixes. We do not build native mobile apps.
Ship the Fixes Before the Next Feature
AI tools got your product to customers faster than any team could have. The cleanup is what lets you keep them. Get the code into a repository you own, audit it, fix data access and payments first, and decide who will look after the app from here. Then go back to building.
