Bolt generates full-stack apps at speed. Here are the production gaps that appear most often in Bolt-built apps — and how to check yours.

Bolt sometimes scaffolds API keys as `VITE_*` or `NEXT_PUBLIC_*` variables, making them visible in the browser. Secret keys must stay server-side only.
Bolt-generated API routes frequently accept request bodies without validation. Unvalidated inputs can cause SQL injection, logic errors, or data corruption.
Default CORS config often allows all origins (`*`). This allows any site to make authenticated requests to your API on behalf of your logged-in users.
An unhandled error in any component crashes the entire page tree. Bolt-generated apps rarely include error boundaries at the route level.
Check these before you share the URL publicly.
