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.
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.
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.
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.
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.
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.
