Protect your Vibe-Coded site: 5 Security checks you can’t skip
Get these right and your vibe-coded app stands a better chance of staying online, secure, and stress-free.
These are the things that make or break you in production:
1. API rate limits
DDoS attacks are real, and they can drain your wallet fast. Also, you don’t want someone hammering your API 100 times per second because you forgot to set limits. Put sane caps in place.
2. Lock down who can call your API
CORS (Cross-Origin Resource Sharing) stops random websites from making browser requests to your API. Set it so only your production domain and local dev environment are allowed.
3. Clean up your console logs
AI agents overshare. Your console shouldn’t be an open diary. Open your app, run through everything, and read the logs carefully. If anything looks too revealing, copy it into ChatGPT or Claude and ask, “Is this safe to log?” You’ll be surprised how much shouldn’t be there.
4. No secret keys in the client
It’s tempting to put keys into the client “just for testing”, AI agents do this too often! Don’t. Set it up properly in Supabase, Netlify, or your platform of choice from the start.
5. Don’t blindly follow AI agents security advice
AI agents are helpful but dramatic. They’ll happily overcook your setup, strip out things you need, and break your app “for security”. Cross-check their advice with at least two different agents before making changes.
Get these right and your vibe-coded app stands a better chance of staying online, secure, and stress-free.
