Production reality check

Your Lovable app looked lovable. Production feels differently.

Separate a Lovable editor or preview problem from a problem in the published application. Then inspect the generated code and connected services instead of prompting around the symptom.

What happened?

Lovable projects commonly combine a Vite frontend with Supabase data, authentication, storage and edge functions. A preview may work while production uses different domains, redirect URLs, environment variables or database policies.

Why this happens

Supabase URL or keys differ between preview and the deployed build.
Authentication redirect and allowed-site URLs do not include the production domain.
Row-level security or an edge function rejects the real user path.
A broad generated edit changed components, schema and dependencies together.

What you can check yourself

Open browser network errors and match them to Supabase or application logs.
Verify production domain, authentication redirect URLs and environment variables.
Test database policies as an unauthenticated user and as two different accounts.
Compare the last working Git commit with the published version.

How to test the fix safely

Export or connect the code to version control, reproduce the fault in staging and test the exact generated diff. Rotate any secret that reached client code before republishing.

When you need a developer

Use senior help when generated database or authorization rules are unclear. Shipvise provides a controlled path from Lovable-generated code through review, staging, deployment and rollback.

FAQ

Questions people ask after the demo stops working

Why does my Lovable app work in preview but not after publishing?

The published app may use a different domain, authentication callback, environment setting, build output or Supabase policy. Compare these before changing UI code.

Should I keep prompting Lovable to fix it?

Only after you have a specific failure and a constrained change. Save the current version and inspect the diff after every generated fix.

Is Shitvise affiliated with Lovable?
