Is Bolt.new secure?
Bolt.new generates standard Next.js / Vite code that has the same security posture as any AI-generated frontend app. 13.4% of scanned Bolt apps ship at least one leaked credential. The platform itself is safe; the output needs review before production.
Bolt.new's platform security is solid — it's StackBlitz's infrastructure. The risk is in the code it generates.
Common issues in Bolt-generated apps: - Secrets in client bundle (environment variable prefix mistakes) - Missing auth on route handlers - CORS set to '*' left over from dev - No rate limits on AI endpoints (bill-shock risk)
Before you ship a Bolt.new app: 1. Open DevTools → Network tab; search for 'sk_' or 'eyJhbG' in JS bundle 2. Scan the GitHub export with Securie 3. Add rate limits on every paid-API route 4. Tighten CORS to your production origins only
Bolt.new is safe for hobbyist apps. For apps with real paying users, pre-deploy scanning is not optional.
