Lovable generates React + Supabase apps fast. Here are the production gaps that appear in nearly every Lovable-built app — and how to know if yours has them.
Default stack: Supabase · Supabase Auth
The part that breaks first
With RLS off, the first curious user who opens devtools can read every other user's rows. Not a hypothetical — it's the default state of most Lovable apps until someone adds the policies, and Lovable doesn't warn you it skipped them.
And then this becomes your life
So you start checking the Supabase dashboard every morning. Refreshing the logs before bed. Watching the auth table for sign-ups you didn't expect. The app was supposed to run itself — instead you've become its night-shift security guard.
You shipped a Lovable app to get something off your plate — a product that earns while you sleep. What you got is a second job you can't quit, because you're the only thing standing between your users' data and the internet.
The good news: every one of these is findable, and most are fixable fast. Here's exactly what tends to be wrong in Lovable apps.
These aren't hypothetical — they show up in the free audits. See the full production-readiness guide →
Lovable creates Supabase tables but frequently skips RLS policies. Every authenticated user can read every row unless you explicitly add policies. Check each table in the Supabase dashboard → Auth → Policies.
Supabase storage buckets are public by default. Lovable-generated file uploads — profile photos, attachments, receipts — are accessible to anyone with the URL. Switch to private buckets with signed URLs.
Service role keys or third-party API keys referenced in Lovable components ship in the browser bundle. Any visitor can extract them from devtools.
Sign-up, sign-in, and magic link endpoints with no rate limit are open to brute force and spam. Supabase offers rate limiting in project settings — it's not enabled by default.
Lovable scaffolds tables without indexes. Queries that are instant at 100 rows time out at 10,000. Add indexes on every foreign key and any column used in a WHERE clause.
Check these before you share the URL publicly.
