I will lovable ai website lovable supabase lovable dev app fix lovable integration

Lovable's preview environment and your live deployment aren't identical, so a build that looks fine in the editor can fail once it goes live. Usually it's a missing environment variable, a config that didn't carry over, or an API call that behaves differently outside preview.

If you haven't manually set up database security rules, there's a good chance any logged-in user can see other users' data, since Lovable doesn't turn this on by default. I run a full security audit across every table and give you a plain-English report of exactly what was open and what's now locked

Yes, this is one of the most common issues I see. It's usually tied to how the app handles the login session in the background, and Lovable's own AI often patches around it without fixing the actual cause. I find the root issue and fix it once, then retest it on your live app to confirm

Both. Most Lovable apps run on Supabase, and the database security rules there are the single biggest source of hidden bugs and data leaks. I check RLS settings table by table, since Lovable can add new tables as you build without protecting them the same way as your original ones.

I offer a rush option if you're on a tighter timeline. Before launch is exactly when this matters most, since that's when real users hit the edge cases your own testing never found. My Launch Lockdown package is built specifically for this window, including 48 hours of support after you go live.

If you've already tried re prompting the AI and the bug came back or moved somewhere else, that's a sign it's patching the symptom, not the cause. I read the actual code and database logic to find what's really wrong, which is usually a five-minute diagnosis for a bug the AI has
