Your Lovable app looked perfect in preview. Then you deployed it, a second user showed up, and it fell over. That gap between preview and production is the single most common thing I fix in Lovable apps — here's why it happens.

Lovable's preview environment has your env vars set for you. Your actual host (Vercel, Netlify, wherever) doesn't — until you add them manually. This alone causes most "it worked yesterday" deploy failures: blank screens, 500s, silent auth failures.
Lovable wires up Supabase fast, but row-level security policies are often an afterthought: either locked down so tight your own app can't query its data, or missing entirely so any user can read anyone else's rows.
It works when you click around alone. It breaks the moment two people are logged in at once — session handling and auth redirects behave differently on the live domain than they did in preview.
Checkout flows built and tested in Stripe test mode fail against real webhook signatures, or checkout succeeds while the app's access state never updates.
Lovable optimizes for speed of generation, not load. Database connections and query patterns that are fine for a demo start timing out or dropping under real concurrent traffic.

/04 Questions
Almost always a preview-vs-production gap: missing env vars, RLS rules that don't match production auth, or connection handling that wasn't built for concurrent sessions. I check all three first.
Yes — Supabase is the default backend for most Lovable apps, so RLS audits and auth fixes are routine work here.
Yes. Test-mode-to-live-mode gaps in checkout and webhook handling are one of the most common Lovable production bugs I see.
Free diagnostic within 48 hours. Most Lovable deploy failures trace back to one of five known causes, so I usually know within the first look.
