Vercel deployment and configuration services
Vercel is the most popular deployment platform for AI-built Next.js apps. It handles hosting automatically, but proper configuration for environment variables, edge functions, and security headers is still your responsibility.
Common Vercel issues we find
Real problems from Vercel codebases we've reviewed.
Missing environment variables
Variables set locally but not configured in Vercel, causing runtime crashes in production that didn't happen during development.
No security headers
Missing Content-Security-Policy, X-Frame-Options, and other headers that protect against XSS, clickjacking, and content injection.
Serverless function timeouts
API routes that take too long hit Vercel's timeout limits, causing 504 errors for users.
Cold start latency
Serverless functions have cold start delays that make API responses slow after periods of inactivity.
No preview deployment protection
Preview deployments publicly accessible with production data connections, creating security risks.
Missing custom error pages
Default Vercel error pages shown to users instead of branded 404 and 500 pages.
Build size limits
Serverless functions exceeding Vercel's size limits due to bundled dependencies, causing deployment failures.
No monitoring or alerting
No error tracking, no uptime monitoring, and no alerts when the app goes down.
Vercel production checklist
Key checks before deploying your Vercel app.
All environment variables set in Vercel dashboard
Security headers configured in next.config or vercel.json
Custom 404 and error pages
Preview deployment protection enabled
Domain configured with proper DNS settings
HTTPS enforced with redirect
Build caching configured for faster deploys
Serverless function regions set close to users/database
Error tracking integrated (Sentry, LogRocket, etc.)
Analytics configured for traffic monitoring

Frequently asked questions
Is Vercel the right platform for my app?
For Next.js apps, Vercel is usually the best choice. For apps with heavy backend processing, long-running jobs, or specific infrastructure needs, other platforms may be better.
How do I add security headers on Vercel?
We configure security headers in next.config.js or vercel.json, including CSP, X-Frame-Options, HSTS, and others. This is a standard part of our deployment service.
Why is my Vercel deployment slow?
Common causes include serverless cold starts, functions deployed in wrong regions, missing caching, and large function bundles. We diagnose and fix all of these.
Can you set up a staging environment on Vercel?
Yes. We configure separate environments with different environment variables, preview deployment protection, and branch-based deployments.
