LaunchCheck

Your v0 app looks finished. Is it?

A polished front end hides a lot: buttons wired to nothing, inner screens that come up blank, a key left in the bundle. We click through your app like a first-time visitor and tell you exactly what did not respond.

The full check adds one read-only test: we ask your database for data using only your app’s public key, the same way a stranger could. Nothing is changed or stored.

14 checks under 30 sec no signup read-only

We scanned 8 live Lovable apps that people shared publicly. 5 had a database table anyone could read without logging in, 2 of those leaked real user data (emails and invite tokens), and 4 had no analytics at all.

Free while in beta. I am collecting data on how AI-built apps break, that is the trade. No signup, no card, no upsell at the end.

Is this safe to run?
