I will fix lovable app not working supabase bugs and deploy to production webhook fixes
Cephaso
About this gig
Built your app with Lovable and now it's broken in production? Blank white screen after deploy. Login failing on your live domain. Stripe not firing. App works in preview but breaks the moment you go live. Or you're burning credits on the same bug that won't die?
That's exactly what I fix.
Lovable gets you 80% of the way there fast. The last 20%, the part that makes it actually work in the real world, is where most projects stall. I step in there.
I find the root cause, fix it at the source, and test on your LIVE domain before handover.
WHAT I FIX:
- App works in preview but breaks in production
- Blank or white screen after deploy
- Missing environment variables (Supabase URL, keys)
- Supabase auth, login and session errors
- OAuth redirects still pointing at localhost
- Custom domain and SSL not working
- Stripe payments and webhooks failing live
- Vercel, Netlify and Replit deployment errors
Send me your app link and the error FIRST.
I'll tell you exactly how I'll fix it before..

App built with Lovable but now it's broken? Login failing, Supabase auth errors, OAuth looping, or your app works in preview but breaks in production? That's what I fix.
I'm a developer who rescues AI built apps and ships them production ready. I fix Lovable bugs, Supabase auth and OAuth, failed deployments, Stripe webhooks, and blank screen errors at the root, not just the surface.
I also build Make.com automations and AI agents that connect your tools and run without breaking.
Send me your app link and the error. I'll tell you exactly how I'll fix it before you order.

FAQ
Why does my Lovable app work in preview but break in production?
The most common cause is missing environment variables. Lovable's preview auto fills your Supabase URL and keys, but your live host (Vercel, Netlify, Replit) does not. I find every missing variable, set it correctly, and test on your live domain.
My app shows a blank white screen after I deploy. Can you fix it?
Yes. A blank screen after deploy is usually a missing env var, a vite.config.ts issue, or a JavaScript error crashing React before it renders. I read the console, find the exact cause, and get your app rendering again.
My Supabase login and OAuth work locally but fail on my live site. Why?
Almost always the Supabase Site URL and redirect URLs still point at localhost, so Google login loops or redirects wrong in production. I fix the auth config, redirect URLs, and session handling so login works on your real domain.
Do you fix Stripe payments and webhooks that fail after deploy?
Yes. Stripe usually breaks in production because the webhook still points at the preview URL or the edge function throws a 500. I repair the webhook endpoint, keys, and checkout flow and confirm a live test payment.
Will you patch it or actually fix the root cause?
Root cause, every time. Patches make the bug come back next week. I find the real source, fix it, secure your Supabase RLS if it's exposed, and hand back a short note on what was wrong so it can't recur.
