Common Lovable Problems We Fix
A Lovable project can look complete in preview while still containing code, configuration, Supabase or deployment problems that only appear during real use.
Preview works, live fails
The preview build behaves correctly, but the published app uses different settings, stale assets, missing live configuration or a different deployed state.
Supabase authentication errors
Login, signup, password reset, OAuth redirect and session handling problems connected to Supabase.
Edge Function 500 errors
Serverless functions fail because of missing secrets, bad request handling, CORS problems, deployment differences or unhandled API responses.
Forms not saving
Submissions appear successful but are blocked by validation, database rules, email logic or integration failures.
API and automation failures
External services reject requests, return CORS errors or require missing environment variables.
Mobile layout problems
Important screens, forms, menus or calls to action break on real mobile devices rather than the builder preview.
Database and RLS issues
Row-level security policies or database rules prevent legitimate users from reading or writing data.
AI fix loops
New prompts add more code over an unresolved root cause, creating fresh errors and making repair harder.

Quick Answers Before You Ask for Help
Do I need to rebuild it?
Usually not. Many Lovable projects can be repaired with targeted fixes, but diagnosis comes first.
Can you work with my existing project?
Yes, where suitable access is provided. We can review the Lovable project, repository, Supabase setup and live deployment.
Can you fix Supabase or deployment issues?
Yes. Supabase, authentication, Edge Functions, API calls and preview/live deployment problems are exactly the kind of issues we investigate.
Lovable's own support policy explains that its support team does not debug individual customer projects. Account problems, billing questions and platform-wide incidents belong with Lovable support. If the problem is inside your application's code, Supabase configuration, authentication, integrations or deployment, send me the details and I'll establish whether I can help.
Why Lovable Apps Break
Lovable is fast and useful, but production apps still need context, constraints, testing, deployment awareness and engineering judgement. A preview can look complete while the live version still depends on configuration, permissions, APIs and real-world user behaviour.
Why the problem usually is not obvious
- Preview can hide production-only issues.
- Supabase rules can block legitimate users.
- Environment variables may be missing from the live setup.
- Edge Functions may fail only when real requests hit them.
- Repeated AI fixes can hide the original cause.
What usually needs checking
- Published deployment behaviour
- Authentication and redirects
- Supabase tables and row-level security
- Edge Function logs
- API responses and CORS
- Mobile user journeys
- Form submissions and data writes
When the build works but its public pages are not being found or ranking, that calls for Lovable SEO diagnosis and repair rather than another code patch.
Stuck in a Lovable Bug-Fix Loop?
If Lovable keeps fixing one issue and creating another, stop adding more patches until the real fault has been found.
Repeated prompts can layer new code over an unresolved root problem. That does not mean Lovable is a bad platform; it usually means the project has reached a point where the code, Supabase configuration, functions, integrations and deployment environment need to be inspected together.
We inspect the existing code, browser errors, Supabase configuration, deployment setup, logs, functions and integrations to identify the actual cause before changing anything else.
The safest first step is to get a proper diagnosis of what is broken.
How I Diagnose and Repair Lovable Apps
I investigate the affected code, configuration and user journey to establish what's causing the problem. Once I've reviewed your enquiry, I'll explain the appropriate next step. Proper technical investigation is paid work, and any subsequent repairs are scoped and quoted separately.
Diagnose
Inspect the live project, codebase, browser errors, Supabase setup, connected services and deployment environment.
Isolate
Identify whether the failure is caused by code, authentication, database rules, Edge Functions, deployment, integrations or responsive design.
Repair
Make targeted changes to the existing project, including data and workflow logic, instead of blindly replacing everything.
Test and Stabilise
Test the affected user journey, mobile layout, forms, authentication, APIs and published version before handover.
What We Check During Diagnosis
A broken Lovable app is rarely solved by looking at one screen. We check the actual path between the user, the interface, Supabase, functions, integrations and the live deployment.
Browser console errors
Network requests
Supabase authentication settings
Row-level security policies
Edge Function logs
Environment variables
Published deployment behaviour
Mobile user journey
Form submissions
API responses
Need a Lovable Developer to Take Over?
We can work with the existing Lovable project, connected repository and Supabase setup where suitable access is provided.
We can repair broken functionality, clean up unstable code, resolve deployment issues and help move an MVP or prototype towards a more reliable production-ready state. The work is practical: understand the current app, find the failure point, make the smallest sensible repair and test the actual user journey.
If the issue is caused by unstable AI-generated code rather than Lovable configuration alone, we can also repair the underlying AI code issues so the project becomes easier to maintain.
Can Your Lovable App Be Repaired?
Many Lovable projects can be repaired without rebuilding, but diagnosis comes before recommending a rebuild.
Usually repairable
- Broken authentication
- Failed forms
- Mobile layout problems
- Incorrect API connections
- Edge Function failures
- Supabase configuration errors
- Deployment issues
- State and dependency bugs
- Incomplete workflows
Repair outcomes we aim for
- Stable app logic that matches the real user journey
- Working Supabase setup, permissions and data writes
- Clearer deployment behaviour
- Fewer preview/live surprises
- More maintainable AI-generated code
- Safer forms, workflows and integrations
A rebuild may be better when
- The structure is duplicated or unmaintainable
- The platform no longer suits the business requirement
- There is a serious security or architecture problem
- The business goal has fundamentally changed
- The current setup cannot be maintained safely
If the issue extends beyond Lovable itself, we can also look at wider website repair and help you decide whether targeted repair or rebuilding is the better route.
If the app is already live and the failure is urgent, our Emergency Website Fixes service covers broken launches, outages and critical website problems.

Frequently Asked Questions
Why does my Lovable app work in preview but not when published?
Preview and production may use different published snapshots, environment variables, API configuration, authentication redirects, deployed functions or cached assets. The live environment needs to be tested separately rather than assuming preview behaviour will carry across.
Can you fix Lovable and Supabase authentication problems?
Yes. We can diagnose login, signup, password reset, OAuth redirects, session handling, URL configuration and row-level security issues.
Can you repair Lovable Edge Function errors?
Yes. We can investigate failed deployments, function-not-found errors, 500 responses, CORS failures, missing environment variables and Supabase function logs.
Can you work directly with my existing Lovable project?
Yes, where suitable access is provided. We can review the existing Lovable project, connected repository, Supabase configuration and live deployment before agreeing repair work.
Can you take over a Lovable app that keeps breaking?
Yes. Repeated AI fixes can create layers of conflicting code. The first step is to identify the underlying issue rather than adding another generated patch.
Do I need to rebuild my Lovable app?
Not necessarily. Many projects can be repaired with targeted changes. A rebuild should only be recommended if diagnosis shows that the existing structure is unsafe, unsuitable or unmaintainable.
Can you help make a Lovable MVP production-ready?
Yes, where the existing project is viable. This may include stabilising code, authentication, database rules, integrations, deployment, responsive behaviour and key user journeys.
How quickly can you diagnose the issue?
We review the URL and the information submitted, then provide a clear next step.
