Fix My Lovable App
That Does Not Work in Production
Your Lovable app works perfectly in the preview but breaks the moment real users arrive. I diagnose and fix it directly on Lovable — deployment errors, auth failures, database problems, and anything else standing between your app and going live.
Common scenario: A founder connected a custom domain on Vercel and every login redirected to an error page. The Supabase redirect URI was hardcoded to Lovable's subdomain and RLS policies blocked reads from the new origin. Twenty minutes to fix once you know where to look.
Part of my vibe-coded app production service — fixing AI-generated code across Lovable, Bolt, v0, Rork, and Replit.
Why this happens
Why Lovable apps break in production
Supabase is the core dependency
Lovable builds every app on Supabase — Auth, Database, and Row Level Security are wired in from the first prompt. In the Lovable preview, RLS policies and auth providers run against a shared dev setup where permissions are often wider than they should be. When you move to a real domain, auth redirect URIs must be registered precisely, environment variables must match exactly, and RLS policies must align with your actual access patterns. These gaps are not obvious in the preview, but they crash real users.
Custom domain deployments expose hidden gaps
Lovable can deploy to its own subdomain, but most teams want their own domain on Vercel or Netlify. That transition surfaces build config differences, missing environment variables, and OAuth callback URL mismatches that never appeared inside the Lovable platform. These are not bugs in the generated code — they are gaps between what Lovable assumes and what a real deployment requires. Closing them quickly takes deep familiarity with Supabase, Next.js, and production auth flows.
What I fix in Lovable apps
Deployment failures
The app builds but does not load, or Lovable says deployed but the URL returns an error. I trace the issue to the source.
Auth not working
Login and signup work in preview but break in production. Session handling, token refresh, OAuth redirects — I fix them.
Supabase connection errors
Database not connecting, rows not loading, RLS policies blocking requests. Fixed with proper env config and query logic.
API call failures
External API calls returning 401s, timeouts, or unexpected errors in prod. CORS, headers, and auth handled correctly.
Mobile layout broken
Looks fine on desktop but breaks on iPhone or Android. Viewport, overflow, and responsive layout issues fixed.
Security problems
API keys exposed in the frontend, missing input validation, XSS risks. Lovable-generated code audited and hardened.
Slow or timing out
Pages load slowly or API calls time out. N+1 queries, unoptimised fetches, and missing caching diagnosed and fixed.
AI integration broken
LLM calls failing, rate limits not handled, streaming broken. AI feature integration fixed properly.
How it works
01
Share your Lovable project
Grant collaborator access on Lovable and describe what is broken. I review the project before quoting.
02
Get a flat-rate quote
I send a fixed-price quote per issue. You approve before I start. No surprises on the invoice.
03
I fix it on the platform
All changes made directly in Lovable. No external repos or confusing merge workflows.
04
Your app goes live
Deploy from Lovable as normal. Your fixed app is live, typically within 48 hours of starting.
Frequently asked questions
What kinds of Lovable issues do you fix?
Deployment failures, broken auth, database connection errors, environment variable problems, Supabase integration issues, broken API calls, mobile layout bugs, and anything else stopping your Lovable app from working in production.
Do you work directly inside Lovable?
Yes. You grant me collaborator access on Lovable and I fix the issues directly on the platform. No external branches or complicated handoffs.
How fast can you fix it?
Most fixes are delivered within 24–48 hours. I give you a realistic timeline before starting — no surprises.
How does pricing work?
I give a flat-rate quote per issue after reviewing your project. You approve the quote before I start. Hourly is also available if you prefer.
What if Lovable created the bug and I do not understand the code?
That is exactly who I work with. You do not need to understand the code. Tell me what is broken and I will diagnose and fix it.
Can you also add features or improve the app?
Yes. Beyond bug fixes I can add functionality, improve performance, or harden the app for scale — all on the Lovable platform.
Using Bolt.new or v0 instead?
Ready to get your Lovable app working?
