Is Vercel safe for production?
Get instant answers about your app's security.
Short Answer
Yes, Vercel can be safe for production - but only after a thorough security review. The platform provides solid infrastructure, while your configuration and code determine whether the final app meets production security standards.
Detailed Answer
Vercel is capable of powering production applications, but production readiness requires deliberate security work beyond the defaults. Here is a production readiness checklist:
**1. Database Security** Verify that every table has appropriate access controls. Row Level Security (for Supabase/Postgres) or Security Rules (for Firebase) must be enabled and tested. Query your database as an unauthenticated user to confirm restrictions work.
**2. Secret Management** Audit all frontend code for hardcoded secrets. Move API keys, database credentials, and service tokens to server-side environment variables. Rotate any keys that were previously exposed in client-side code.
**3. Authentication and Authorization** Enforce email verification, strong password policies, and rate limiting on auth endpoints. Verify that authorization checks exist on every API route - not just the frontend UI. Test by calling APIs directly without a valid session.
**4. Security Headers and HTTPS** Configure Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. Ensure all traffic uses HTTPS with no mixed content.
**5. Monitoring and Incident Response** Set up error logging, uptime monitoring, and alerts for unusual activity. Have a plan for rotating credentials and notifying users if a breach occurs.
Complete this checklist and run a VAS scan to verify. If your scan returns no critical or high findings, your Vercel app is ready for production traffic.

Expert Perspectives
“Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial.”
“The problem with AI-generated code isn't that it doesn't work - it's that it works just well enough to ship, but contains subtle security flaws that are hard to spot.”

Can Vercel apps scale for production workloads?
Scalability depends on your architecture and hosting setup, not just the tool you built with. Vercel apps typically run on proven infrastructure (Vercel, Netlify, Supabase, Firebase, etc.) that handles significant traffic. The security concern at scale is ensuring your access controls, rate limiting, and monitoring scale with your traffic - a database without RLS is dangerous at any scale, but catastrophic at production scale.
Do Vercel apps meet compliance requirements like SOC 2 or HIPAA?
Compliance depends on your entire stack, not just the build tool. The underlying infrastructure providers (AWS, GCP, etc.) often have compliance certifications, but your application layer must also meet requirements: encrypting sensitive data, implementing access logging, handling data deletion requests, and configuring proper access controls. Run a security scan first, then consult a compliance specialist for your specific regulatory needs.
What should I do before launching a Vercel app to real users?
Before launch: 1) Run a VAS security scan and fix all critical/high findings, 2) Test authentication flows including password reset and session expiry, 3) Verify database access controls by testing as different user roles, 4) Review all environment variables to ensure no secrets are in frontend code, 5) Set up error monitoring and alerts. A pre-launch security scan takes minutes and can prevent data breaches that take months to recover from.
