How to Secure Your Bolt.new App
Last updated: January 12, 2026
Bolt.new generates full-stack apps in minutes, but the generated code often prioritizes speed over security. Here's how to secure your Bolt app before going to production.

Step-by-Step Security Guide
1. Audit Generated Code for Secrets
Search your codebase for hardcoded API keys. Bolt often generates code with keys directly in source files.
grep -r 'sk-' . # Find OpenAI keys
grep -r 'sk_live' . # Find Stripe keys2. Move Secrets to Environment Variables
Create a .env file and update your code to use process.env. Never commit .env to git.
3. Configure Database Security
If using Supabase or Firebase, configure Row Level Security or Security Rules. Without these, your database is publicly accessible.
4. Add Security Headers
Configure Content-Security-Policy, X-Frame-Options, and other headers in your next.config.js or hosting platform.
5. Disable Source Maps in Production
Source maps expose your code. Disable them in production builds.
// next.config.js
productionSourceMaps: false6. Scan Before Launch
Run a VAS security scan to catch anything you missed. We test your deployed app for real vulnerabilities.

Ready to Secure Your App?
Security is an ongoing process, not a one-time checklist. After implementing these steps, use VAS to verify your Bolt.new app is secure before launch, and consider regular scans as you add new features.
Frequently Asked Questions
Which database does Bolt.new use?
Bolt can use Supabase, Firebase, or other backends depending on your prompt. Check your project for supabaseClient.ts or firebaseConfig.ts. Each requires different security configuration: Supabase needs RLS, Firebase needs Security Rules.
How do I find hardcoded secrets in Bolt-generated code?
Use grep in terminal: 'grep -r "sk-" .' for OpenAI keys, 'grep -r "sk_live" .' for Stripe keys. Also search for 'apiKey', 'secret', and 'password'. Check .env files aren't committed to git (should be in .gitignore).
Why does Bolt include API keys in the code?
Bolt prioritizes getting a working demo quickly. It generates functional code without considering that keys will be exposed in the browser. Always move API keys to environment variables and server-side functions before deployment.
How do I deploy a Bolt app securely?
1) Move all secrets to environment variables in your deployment platform (Vercel, Netlify). 2) Disable source maps (productionBrowserSourceMaps: false). 3) Configure security headers. 4) Set up proper database security rules. 5) Run VAS scan before going live.
