Deploy your Next.js app to Vercel
Step-by-step deployment help for Next.js apps on Vercel. We fix Next.js-specific deployment issues, configure Vercel, and get your app live. From $19.
Next.js issues we fix before deploying
Common Next.js problems that affect Vercel deployments.
Unprotected API routes
Next.js API routes and server actions without authentication checks, allowing anyone to call them directly.
Server action data exposure
Server actions that return sensitive data to the client or don't validate user permissions before modifying data.
Incorrect middleware configuration
Auth middleware that doesn't cover all protected routes, uses wrong matchers, or can be bypassed with URL manipulation.
Missing ISR/SSG configuration
Pages that should be statically generated are server-rendered on every request, causing unnecessary load and slower responses.
Vercel deployment issues we check for
Common Vercel problems that break Next.js apps in production.
Serverless function size exceeds 50MB limit
AI tools bundle heavy dependencies into API routes without tree-shaking, pushing serverless functions past Vercel's 50MB compressed size limit and failing the build.
Edge runtime incompatible with Node.js APIs
Generated code uses fs, crypto, or other Node.js built-ins inside Edge Runtime routes, causing deployment failures since Edge only supports a subset of Web APIs.
ISR revalidation not triggering correctly
Incremental Static Regeneration configured with stale revalidate values or missing on-demand revalidation hooks, serving outdated content indefinitely.
Environment variables missing in production
Secrets added to .env.local but not configured in the Vercel dashboard, causing runtime crashes only in production while working perfectly in local dev.

Frequently asked questions
How do I deploy a Next.js app to Vercel?
We handle Next.js deployments to Vercel end to end. Start with our code audit ($19) to identify deployment blockers specific to your Next.js project, then we configure Vercel, fix issues, and get your app live in production.
What Next.js issues affect Vercel deployments?
Next.js projects commonly have unprotected api routes and server action data exposure. On Vercel, these combine with serverless function size exceeds 50mb limit and edge runtime incompatible with node.js apis to cause deployment failures.
Can SpringCode deploy my Next.js project to Vercel?
Yes. We specialize in deploying Next.js applications to Vercel. We audit your codebase for Next.js-specific issues, configure Vercel correctly, and handle the full deployment so your app runs reliably in production.
What does Next.js deployment to Vercel cost?
Our code audit ($19) identifies all Vercel deployment blockers in your Next.js project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
