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.
Default stack: Supabase or SQLite · varies
The part that breaks first
Bolt's speed is the trap: it'll wire a working API route in seconds, secret key included as a VITE_ variable that ships straight to the browser. Your app works perfectly in the demo. It also hands your keys to anyone who opens the network tab.
And then this becomes your life
Now every deploy is a held breath. You re-read the env config before you push. You grep the bundle for keys you might have leaked. You tell yourself you'll 'do a proper security pass later' — and 'later' becomes a tab you never close.
Bolt promised you'd build the thing in a weekend and move on. Instead you're the one-person ops team for an app you don't fully understand, patching holes you didn't know you'd dug, on a codebase that moved faster than you could read it.
The good news: every one of these is findable, and most are fixable fast. Here's exactly what tends to be wrong in Bolt apps.
These aren't hypothetical — they show up in the free audits. See the full production-readiness guide →
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.
