RESCUE A BROKEN APP
Keep your app.
Get past the blocker.
When another prompt isn’t solving the problem, bring a Joylo engineer directly into your project. Keep the work you have done and get a clear plan for what needs fixing.
Expert Assist: $500 for 10 architect hours.
First response within 24 hours.
Less explaining.
More useful context.
You should not have to become the technical go-between. With your permission, your engineer can review the code and history available in Joylo before you have your first conversation.
- 01
Show us the problem.
Request Expert Assist inside your project. Tell us what you expected to happen and what happens instead. Already built elsewhere? We can review the import first.
Your existing app is the starting point. - 02
See the plan.
A Joylo engineer reviews the issue, your code and available project history. You agree what needs doing and the hours involved.
First response within 24 hours. - 03
Get the work done.
Your engineer works in the project, logs the time and reviews the changes. You approve the work before it is merged.
No additional hours without your approval.
The response SLA is the time to hear from us, not a promise that every problem will be fixed within 24 hours. Engineers work during business hours.
WHAT EXPERT ASSIST COVERS
What is getting
in your way?
A login that fails. Payments that do not connect. An app that works in a preview but will not go live. We investigate the cause and agree the right fix.
Choose an issue to see the kind of work our engineers handle.
01Something is broken
We trace bugs, broken builds and repeated errors to their cause, then work on the affected feature. If a larger rebuild is the better option, you see the reasoning and scope before agreeing.
02Login or payments fail
We work on account access, permissions, sessions, payment flows and third-party connections. The aim is a complete workflow your customers can actually use.
03Your app will not go live
We help with deployment, configuration, your domain and the services your app depends on. We review what is preventing launch and explain the work needed.
04It struggles as usage grows
We investigate slow pages, overloaded processes and database problems. Security findings, unreliable integrations and scaling concerns can also be included in the agreed work.
Know what you are
agreeing to.
Expert Assist is a fixed block of engineering time. You see how it is used, and you decide before any additional paid work begins.
Built elsewhere? Bring it here.
Standard migration from Lovable, Replit, Bolt, v0 and other supported repositories is free on paid plans. We check the project first, so you know what can be brought across.
Heavily customised backends or monorepos may need an architect-led migration at a fixed $2,000, quoted before you commit. You are not charged for an unsuccessful attempt. Co-Build customers can use their included engineering hours.
An agreed launch. A written guarantee.
If your app needs a larger effort to launch, agree the scope and purchase the engineering hours we recommend. We then guarantee that scope will go live. If our estimate falls short, we cover the engineering overrun, subject to the guarantee’s conditions.
Read the Production GuaranteeWhat the $500 covers,
and what it does not.
One block of Expert Assist is 10 architect hours. This is the work those hours go on, and the things that are handled outside those hours.
| What you need | What happens | Cost |
|---|---|---|
| In scope with Expert Assist | ||
| Scoping the problem | An engineer reviews the issue, your code and the available project history, then agrees what needs doing and the hours involved. | Not charged |
| Bugs, broken builds and repeated errors | Traced to their cause, then the affected feature is worked on. If a larger rebuild is the better option, you see the reasoning and scope first. | From your 10 architect hours |
| Login or payments failing | Account access, permissions, sessions, payment flows and third-party connections, worked on as a complete workflow. | From your 10 architect hours |
| An app that will not go live | Deployment, configuration, your domain and the services your app depends on, with the work needed explained before it starts. | From your 10 architect hours |
| Struggling as usage grows | Slow pages, overloaded processes and database problems investigated. Security findings, unreliable integrations and scaling concerns can be included in the agreed work. | From your 10 architect hours |
| Handled separately | ||
| Standard migration from Lovable, Replit, Bolt or v0 | The project is checked first, so you know what can be brought across before anything moves. | Free |
| A heavily customised backend or a monorepo | An architect handles the migration by hand, quoted before you commit. You are not charged for an unsuccessful attempt. | Fixed $2,000 |
| Ongoing monitoring of a live app | 24/7 automated monitoring with engineers responding during business hours. Separate from getting the agreed scope completed. | Production Support, from $299 a month |
| Code written by a Joylo engineer that breaks | Warranty work on any plan. You do not need a Production Support subscription for it. | Free |
| A scope too large for one block | Agree the scope and buy the engineering hours Joylo recommends, and that scope is guaranteed to go live, subject to the guarantee's conditions. | The recommended hours, agreed up front |
| More hours than the block you bought | Nothing additional starts without your approval, and unused hours never expire. | Agreed before you pay |
Scoping is free, so the conversation costs you nothing. See how Expert Assist is priced.
The fix is one thing.
What happens next matters.
Every build is checked by the AI Confidence Score across security, reliability, scalability, integrations and code quality. You can see the findings before you ship.
Our engineering comes with a warranty.
If code written by a Joylo engineer breaks, that is warranty work and we fix it free on any plan. You do not need a Production Support subscription for that.
Ongoing support for a live app.
Production Support starts at $299 per month. It combines continuous automated monitoring with engineers who respond during business hours. It is separate from getting the agreed launch scope completed.

Before you
hand it over.
Your app, your budget and your next step.
Can someone fix my AI-built app without starting over?
Yes. We start by reviewing what you have and what is broken. A Joylo engineer can fix an existing app after it is in your project. If rebuilding part of it is the better approach, the engineer explains why and agrees that work with you first.
What will the engineer know before we speak?
With your permission, the engineer can review your code and the build history and errors available in Joylo. For an imported app, we review the available files and ask for any missing context. We do not assume that another builder's entire history transfers with the app.
What if the problem takes more than 10 hours?
Your engineer explains the remaining work and seeks approval for additional hours before continuing. If you have agreed a launch scope and purchased the recommended hours under the Production Guarantee, engineering overruns needed to finish that scope are our responsibility, subject to its conditions. New scope is agreed separately.
Will I keep ownership of my code?
Yes. You own the application and the work added to it. Joylo uses a conventional React, Node and Postgres stack, and you can export your app and host it elsewhere.
Does the 24-hour SLA mean my app will be fixed in a day?
No. Expert Assist provides a first response within 24 hours. The time to resolve an issue depends on the work involved. You get a diagnosis and a plan, with engineering carried out during business hours.
Do I need Production Support for the fix?
No. Expert Assist pays for agreed engineering work. Production Support covers ongoing operation of your live app. Warranty fixes for code written by a Joylo engineer are free on any plan, whether or not you have Production Support.
