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.
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 keysCreate a .env file and update your code to use process.env. Never commit .env to git.
If using Supabase or Firebase, configure Row Level Security or Security Rules. Without these, your database is publicly accessible.
Configure Content-Security-Policy, X-Frame-Options, and other headers in your next.config.js or hosting platform.
Source maps expose your code. Disable them in production builds.
// next.config.js
productionSourceMaps: falseRun a VAS security scan to catch anything you missed. We test your deployed app for real vulnerabilities.
Avoid these common Bolt.new security pitfalls:
Use these tools to maintain security throughout development:
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.
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.
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).
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.
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.
