Fix a Broken Lovable App

Lovable turns a chat prompt into a full React + Supabase app fast — but that speed means security and configuration steps get skipped. The most common Lovable support request we see is a blank white screen after building or deploying, usually caused by a JavaScript error, a broken Vite config, or Supabase security rules left wide open. We fix all three.

Common Lovable problems we fix

Ranked by what actually breaks a launch, not the order they occurred to us.

Critical

Blank white screen after building or deploying

We open the browser console, find the actual JavaScript error (undefined variable, failed import, dependency conflict) and fix the render-breaking bug, not just the symptom.

Critical

Supabase row-level security left open in test mode

We write real per-user RLS policies table-by-table so your database isn't readable by anyone with the anon key — this is the single most common security hole we find in Lovable apps.

Critical

Missing environment variables break production only

We audit every env var your app depends on and make sure Lovable Cloud secrets are actually present in the production environment, not just local preview.

Critical

AI-edited Vite config breaks the production build

We repair the base path, plugin order, and security headers so built files load correctly instead of 404ing in production.

Warning

CORS errors calling Supabase from the deployed app

We fix allowed-origin configuration and API client setup so requests succeed in production the same way they do in the Lovable preview.

How the Lovable rescue works

Send us your Lovable project on WhatsApp — GitHub link or a zip export. We run a free Launch Readiness scan, send back a scored report of what's broken, then fix it at a fixed price. Most Lovable rescues ship in 48–72 hours. See pricing or read about our 4-step process.
