Lovable App Repair & Troubleshooting

Is your Lovable app broken?

Have you built an application using Lovable, only to find that something isn’t working? Perhaps users cannot log in, your Supabase database isn’t connecting, changes aren’t saving or your published app behaves differently from the preview.

AI Repair Directory helps you troubleshoot common Lovable problems and find specialists who can repair AI-built applications.

Common Lovable app problems

  • Supabase connection errors: Your app cannot read or save database information.
  • Broken login and authentication: Users cannot sign in, register or maintain their sessions.
  • Database errors: Records fail to save, tables are missing or queries return unexpected results.
  • Blank screens: Your application loads without displaying the expected content.
  • Deployment problems: The published app behaves differently from the preview.
  • Broken buttons and forms: Interactive elements stop responding or submitting information.
  • API integration failures: External services return errors or unexpected responses.
  • AI-generated code problems: Changes introduce bugs or break previously working features.
  • Mobile layout issues: Pages look correct on desktop but fail on smaller screens.

How to troubleshoot a broken Lovable app

  1. Identify the problem: Determine which feature stopped working and whether the issue occurs in preview, production or both.
  2. Check browser errors: Open your browser’s developer tools and inspect the Console for error messages.
  3. Inspect network requests: Look for failed API calls, authentication errors and unsuccessful database requests.
  4. Check Supabase: Confirm that your project is active, the expected tables exist and your app is connected to the correct project.
  5. Review database permissions: Check Row Level Security policies where applicable. Avoid disabling security protections as a quick fix.
  6. Test authentication: Check sign-in settings, redirect URLs and session handling.
  7. Review recent changes: Identify whether a new feature, prompt or code change introduced the problem.
  8. Back up before making changes: Preserve working code and important data before attempting significant repairs.
  9. Retest the published app: Check that the repaired feature works on desktop and mobile.

Why do Lovable apps stop working?

AI-built applications can experience the same problems as traditionally developed software. Database permissions, API changes, authentication settings, code errors and deployment differences can all cause failures.

Repeatedly asking an AI builder to fix a problem without understanding its cause may introduce further changes. Identifying the underlying error first is usually more effective.

When should you hire a Lovable specialist?

Professional help may be useful when:

  • Your application is live and customers cannot use important features.
  • Database or authentication errors prevent users from accessing their information.
  • Attempts to fix one feature repeatedly break another.
  • You need to investigate complicated API or Supabase problems.
  • You want to improve the reliability and security of an AI-built application.

A specialist can review the application, investigate errors and recommend appropriate repairs.

Frequently asked questions

Can a broken Lovable app be repaired?

Many Lovable application problems can be fixed by correcting code, database permissions, API configurations or authentication settings. The solution depends on the underlying cause.

Why is my Lovable app not connecting to Supabase?

Possible causes include incorrect project configuration, authentication problems, database permissions, Row Level Security policies or failed network requests.

Why does my Lovable app work in preview but not when published?

Differences in deployment settings, environment configuration, authentication redirects or application behaviour can cause production-only problems. Inspect the published app’s browser errors and network requests.

Can a specialist fix Lovable code without rebuilding my app?

Often, yes. A specialist may be able to identify and repair individual components or integrations while preserving the rest of the application. However, extensive structural problems may require more significant changes.
