Should I rewrite my vibe-coded app from scratch?
Usually not as a first step. Many apps need a handful of targeted fixes. A rewrite is the right call only after someone has read the code and can tell you exactly why fixing it would cost more

How to pick who fixes your vibe-coded app
Your app was built fast with AI and now something is wrong. Here is who can fix it, what they should do before they quote, the questions to ask and the red flags to walk away from

The short answer
How to pick who fixes your vibe-coded app
Pick someone who reads your code and the live app before they quote, explains the problems in plain English, ranks them by what they would cost you, fixes what you have before suggesting a rewrite, hands over the code and every account, and stays reachable after launch. Ask to see apps they have fixed that are still live today.
How much does it cost to fix a vibe-coded app?
It depends on what is broken, which is why the first step should always be reading the code. Anyone who quotes a firm number before looking is guessing. At Blinkz every job is quoted on a free call
Can the AI tool that built it fix it?
Sometimes, for a single bug you can describe. It cannot tell you which of your problems matter most, and it will not notice the ones nobody asked it about, like missing backups or data that other users can read
How long does it take to fix a vibe-coded app?
An app check takes five business days at Blinkz and tells you what is wrong and how to fix it. How long the fixes take depends on what the check finds, and that gets agreed before any work starts
Who can fix a vibe-coded app?
There are four kinds of people you can call, and each one suits a different situation.
- The person who built it. They know the code, but if the same process produced the problems, it will usually produce more.
- A freelancer from a marketplace. Good for one clear bug you can describe. Hard to judge, and they rarely stay once the job is done.
- An agency. Good for big rebuilds with a budget to match. Often slower to start, and your app may be one of many.
- An engineer who owns the outcome. One person who checks the app, fixes what matters and stays reachable after launch. That is the role we play at Blinkz.
What should happen before anyone quotes?
They should read the code and use the live app. They should ask what depends on it: users, payments, a launch date, an investor demo. A quote given before anyone has looked at the code is a guess, and you end up paying for the guess when it turns out wrong.
What should you ask them?
- Will you read the code before you give me a number?
- Can you explain each problem in plain English?
- How will you decide what to fix first?
- Can I see apps you have fixed that are still live today?
- Will I own the code, the accounts and the keys when you are done?
- What happens if something breaks a month after you finish?
- Who exactly will work on my app?
What are the red flags?
- They want to rewrite everything before reading the code.
- They cannot explain the problem without jargon.
- They bill by the hour with no cap and no scope.
- They keep the accounts, the hosting or the keys in their own name.
- They promise the app will be hack proof.
- They disappear the day the invoice is paid.
What does a good first week look like?
By the end of the first week you should have a ranked list of what is wrong, the fix for each problem, and a clear answer on whether the app needs small repairs or real rebuilding. You should understand all of it without a developer in the room.
How does Blinkz do it?
We start with an app check. In five business days an engineer reads what the AI wrote, ranks what will break and writes the fix for each problem, and you keep the report whether or not we do the fixes. If the app needs real work, we do it as a build or rescue with the scope agreed before any code. If you want one engineer responsible for it every month after that, that is on call.

What an app check covers
An app check is an engineer reading the app your AI tools wrote, ranking what will break and writing the fix for each problem. Here is every area it covers, how the five days run and what you keep at the end 
The coding agent never holds production credentials
An agent with a production database URL will sooner or later run a migration or a cleanup against it, so production secrets never enter its env
Keys go in headers, never in URLs
A URL is written to server logs, CDN logs, browser history and error trackers, so an API key in a query string is a key in five places
Bring what you have. We’ll tell you where it stands
You’ll leave the call knowing what’s risky and what to do next
