A web app bug fixing service repairs a live application that worked before and now has a broken login, payment, deployment, data flow or integration. The job is to reproduce the failure, identify the affected system and restore that flow without turning it into a rebuild.
App Rescue Desk works on React, Next.js, Node.js, Supabase, PostgreSQL and Stripe. The app can come from your own team, an agency, a freelancer or an AI builder such as Lovable, Bolt, v0, Replit or Cursor.
The scope depends on the failed production flow and the systems it crosses, not on who wrote the original code.
TL;DR
- App Rescue Desk fixes live web apps on React, Next.js, TypeScript, Node.js, Supabase or PostgreSQL, and Stripe. Who built the app does not change the scope.
- Lovable apps and other AI-built apps are still in scope. They are one of the groups of apps we fix.
- Every job starts with a $99 diagnosis. We reproduce the failure, find the cause and give you a fixed repair price. If you approve the repair, the $99 is credited toward it.
- Nothing in production changes until you approve the scope and the price in writing.
Does this service only work on Lovable apps?
No. Lovable apps are in scope, and so is any web app on the stack in this post, with or without an AI builder.
Our first posts were about Lovable: what leaving Lovable involves, one layer at a time, why a GitHub export does not move the whole app, when a migration makes sense, and the nine gaps a preview never tests. All four are still valid.
After that, we looked at the failures that Lovable owners describe in public forums. Most of them did not start in Lovable. They started in parts that every web app has: auth, the database, the build and payments.
App Rescue Desk is not affiliated with Lovable, Supabase, Stripe or any AI builder. We name them because many owners use them.
Why the same failures happen in apps that no AI built
An AI builder does not make its own auth, database or payment system. It connects standard tools, and those tools fail the same way when a person writes the code.
Here are eight failures that owners often report:
| What the owner sees | Where the cause usually is | Only in Lovable apps? |
|---|---|---|
| The password reset link opens the wrong page or fails | The list of allowed redirect addresses in the auth settings | No. Most hosted auth services use a list like this. |
| The data is in the table, but the app shows an empty list | A row-level security policy that does not match the signed-in user | No. Row-level security is a PostgreSQL feature. |
| You changed an API key, and the live app still uses the old one | The build tool writes public variables into the code at build time | No. Vite and Next.js both do this. |
| The live app shows a blank screen | One of at least three separate causes, and each one needs a different fix | No. It is a common failure in Vite and React apps. |
| Next.js shows a client-side exception after deploy | Browser code threw an error that no error boundary caught; the Console and failed requests narrow the cause | No. The failed browser code, response or release needs diagnosis. |
| The live app returns 502 Bad Gateway after deploy | A gateway or proxy cannot get a usable response from the app, function or origin behind it | No. It can happen across Next.js, Vercel, Railway and other deployed web apps. |
| The customer paid, but the app did not give access | The webhook signing secret is different in test mode and live mode | No. Stripe gives test and live endpoints different secrets. |
| Signup emails stop, and users see a rate-limit error | The email send limit of the auth service | No. Supabase Auth applies it to every project, whatever built the app. |
In every row, the fix is in the same place no matter who built the app. So we now organize the work around those layers: auth, the database, the build and payments.
An app built fast can still be a real production app with paying users. When one of its layers changes, someone has to own that layer.
Which production failures are in scope?
We take web apps that worked and then broke. The reports usually look like this:
- Users cannot sign in, confirm their email or reset their password.
- A customer pays, and the app does not give access.
- The app stopped working after a deploy.
- An API, integration or webhook stopped sending or receiving data.
- Data is missing, or a user can see data that belongs to someone else.
- The developer or agency left, and nobody owns the code now.
This is the stack we work on:
| Layer | In scope |
|---|---|
| Frontend | React, Next.js, TypeScript |
| Backend | Node.js APIs and server functions |
| Database | Supabase, PostgreSQL, row-level security |
| Payments | Stripe checkout, subscriptions and webhooks |
| Auth | Sign-in, email confirmation, password reset, sessions |
| Deploy | Build settings, environment variables, hosting configuration |
| Who built it | Your own team, an agency, a freelancer, Lovable, Bolt, v0, Replit, Cursor |
If your stack is different, say so in the intake form. We check the technology, the access and the business impact before we accept paid work. If we cannot take responsibility for the fix, we tell you.
The full service description is on the bug fixing service page.
Which jobs are outside the scope?
These are outside our scope:
- WordPress and other CMS sites, plugins or themes
- PHP, Laravel and Rails apps
- Native iOS and Android apps
- Hacked-site cleanup, malware removal and penetration testing
- New features, full rewrites and visual redesigns
- Monthly maintenance retainers
If you think someone is inside your system right now, contact a security incident specialist first. Do not send evidence through a public form.
We also do not promise 24/7 response or a fix within a set number of hours. The start time depends on access and on the size of the problem. You get the plan before we start.
How is this different from other app rescue services?
There are now many services for vibe coding rescue and software project rescue, and there are freelancers who will take any bug. They suit different jobs. This is how they compare:
| Many AI-app rescue services | Hourly freelancer | App Rescue Desk | |
|---|---|---|---|
| What they take on | Unfinished AI-built apps that need to be finished and launched | Any task you describe | A live web app that worked and is broken now |
| Which apps | Apps from AI builders | Depends on the person | Any app on our stack, whoever built it |
| First step | A free call or a free audit | Usually paid hours from the start | A $99 diagnosis that reproduces the failure, credited toward the repair |
| Price | A fixed project price or an hourly rate | An hourly rate | A fixed repair price, agreed after the diagnosis |
| Speed promise | Often “24 hours” or “fast” | Varies | No fixed-hours promise. You get the plan once access is confirmed. |
| What you get at the end | Working code, sometimes handover notes | Varies | A written record of the app before the change, the cause, the change, how we tested it and what is still open |
For an owner, two of these rows matter most.
The first is the kind of problem. A free call works well to scope an app that is not finished yet. A broken production flow is harder to price: until someone reproduces the failure and finds where it starts, any price is a guess. The $99 diagnosis pays for that work, and it comes off the repair price if you go ahead.
The second is proof. After a rescue, you should be able to see what was broken and how anyone knows it works now. We write down how the app behaves before we touch it. We trace the failure to one layer. We make the change in a way that can be rolled back, and we test the flow again afterwards. You get all of it in writing.
Who runs App Rescue Desk?
App Rescue Desk was founded by Alp Bozkurt, a software engineer with 30 years of work on systems that are not allowed to fail.
He started by fixing bugs in a real-time defense system with more than one million lines of code. Later he built avionics software to DO-178B, the safety standard for airborne software, where a change is done only when it is verified and the evidence is on file. He once restarted a stalled project after its original team had left and took it through certification with a new team in seven months. From 2018 to 2025 he was a principal software engineer at a telecom software company.
Today he is an independent software consultant and builds new products the fast, AI-assisted way, the same way many of the apps we fix are built. The method he brings to them has not changed: record how the app behaves, find the cause, make one change that can be rolled back, and prove the flow works again.
What happens after you send us a broken app
Every app goes through the same six steps, and you see the result of each one.
- We learn what broke and what it costs you. Which flow, since when, and for how many users.
- We write down how the app behaves now, before anyone changes anything.
- We reproduce the failure and trace it to one layer.
- You get a written finding and a fixed repair price. Nothing in production changes until you approve both in writing.
- We make the repair and test the flow again. Every production change can be rolled back.
- You get a close-out. It shows what was broken, what we changed, how we checked it and what is still open.
You keep ownership of your accounts, your code and your data the whole time. More on this on our security page. The pricing logic is on the bug fixing service page.
Sometimes the right result is a clear finding and no repair. A paid diagnosis does not mean every app can be fixed, and when one cannot, we say so.
Is your app a fit? A 7-point check
Answer each question with yes or no. It takes about 10 minutes.
- Does the app have real users, payments or business data?
- Did something work before and stop working now?
- Is the stack in the table above, or close to it?
- Can you give access to the code repository and to the hosting and database accounts?
- Can you describe one failed flow, step by step?
- Do you want a fix, rather than a new build or a redesign?
- Can you accept a diagnosis as the first result, before any repair?
How to read the result:
| Result | What it means |
|---|---|
| 7 yes | The app is a good fit for a diagnosis. |
| No on question 2 | A critical flow never worked. We can still look at it, but we check the fit separately. |
| No on question 4 | Get access first. Without it, nobody can fix the app, us included. |
| No on question 6 | You need development work. A development team is a better match for that. |
Passing this check does not guarantee a fix. It tells you that a diagnosis is a sensible first step.
Frequently asked questions
Can you rescue a broken Lovable app?
Yes. A Lovable app gets the same diagnosis and the same process as any other app. Export, dependence on the platform and migration are still part of that work.
Do you fix apps that no AI builder touched?
Yes. Hand-written React, Next.js and Node.js apps are in scope, and so are apps from agencies and freelancers. Who built the app does not change the process.
Do you fix WordPress sites or mobile apps?
No. WordPress and other CMS sites, PHP, Laravel and Rails apps, and native iOS and Android apps are outside our scope.
Why is the diagnosis paid when other services offer a free call?
Because the diagnosis is real work. We reproduce the failure and find the layer where it starts, and you keep the written finding even if you stop there. It costs $99, and if you approve the repair, the $99 is credited toward it.
Do I need to know which part of the app is broken?
No. A description of the symptom is enough, for example: “Since Tuesday, users do not get the password reset email.” Finding the layer is the job of the diagnosis.
Can you take over an app after the developer leaves?
Yes, in steps. First we help you collect the access you need. Then we diagnose the urgent failure. A full takeover is a separate scope with its own price.
Where to start
If sign-in, payments, a deploy or your data broke on a web app, start with the $99 Incident Diagnosis. It finds the cause and gives you a fixed repair price, and nothing in production changes until you agree to both.
