v0.dev Security Guide
Security guide for Vercel v0 deployments.
v0 Security Considerations
v0.dev generates React components and full apps deployed on Vercel. While Vercel provides good infrastructure security, application-level security is your responsibility.
1. Server Components vs Client Components
Keep sensitive logic in Server Components. Never expose API keys or database connections in Client Components.
2. API Route Protection
Always validate authentication in API routes. v0-generated code may not include middleware by default.
3. Supabase Integration
If your v0 app uses Supabase, follow our Supabase RLS Guide to secure your database.
4. Automated Scanning
Scan with Aphido to automatically detect exposed credentials and missing security policies.
