Fix My v0 App
That Does Not Work in Production

Server / client boundary confusion

v0 is purpose-built to generate UI, and it does that well. The problem is Next.js App Router has strict rules about which components can use state, event handlers, or browser APIs — they must be marked with "use client". v0 frequently generates components with useState or onClick handlers that are missing this directive, causing hydration errors that crash immediately in production but never appear in the v0 preview (which uses a simpler rendering model).

TypeScript and integration mismatches

v0 generates isolated components with inferred or loosely typed props. This compiles cleanly on its own but breaks immediately when integrated into an existing codebase with strict TypeScript settings, a real data model, or third-party libraries that have their own type definitions. API routes, authentication layers, and database schemas all need to be connected manually — and that wiring is where v0-generated code most commonly fails.

TypeScript errors

v0 generates TypeScript that looks right but breaks on build. Type mismatches, missing generics, and incorrect interfaces resolved.

Server vs client boundary errors

"use client" / "use server" confusion is the most common v0 issue. I fix the component tree and Next.js App Router boundaries.

Vercel deployment failures

Builds locally but fails on Vercel. Environment variables, edge runtime issues, and deployment config fixed.

API route errors

Next.js API routes returning 500s or not authenticating correctly. Route handlers, middleware, and response types fixed.

Tailwind styling broken

Components look different in production than in the v0 preview. Purge config, class conflicts, and custom theme issues resolved.

Auth integration issues

NextAuth.js, Clerk, or custom auth not working correctly with v0-generated pages. Session handling and protected routes fixed.

Database and ORM errors

Prisma, Drizzle, or direct SQL connections failing. Schema mismatches, migration issues, and query errors resolved.

Mobile responsiveness

v0 sometimes generates desktop-first layouts that break on mobile. Responsive fixes applied across the component tree.

01

Share the v0 project

Share your v0 project link or export to GitHub. Describe what is broken or what you want to work.

02

Get a flat-rate quote

I identify the issues and send a fixed price. You approve before I touch anything.

03

I fix the code

TypeScript, API routes, component boundaries, styling — fixed in the codebase with clear explanations.

04

Deploy to Vercel

Your fixed app deploys normally. Live and working, typically within 48 hours.

What v0 issues do you fix?

Component rendering errors, TypeScript type mismatches, broken API routes, Vercel deployment failures, Tailwind styling issues, missing server/client boundary handling, and any production bugs that did not show up in the v0 preview.

How do I share my v0 project with you?

Share the v0 project link or export the code to GitHub. I can work with either — whatever is easier for your setup.

I do not understand the code v0 generated — is that a problem?

Not at all. That is typical. Tell me what is broken or what you want to happen, and I will fix the code without requiring you to understand it.

How fast can you deliver the fix?

Most fixes within 24–48 hours. Complex issues may take longer — I give you an honest timeline before starting.

How does pricing work?

I review the project, identify what needs fixing, and send a flat-rate quote per issue. You approve before I start.

Can you also help me extend the v0 app with new features?

Yes. Beyond fixing bugs I can add pages, integrate APIs, implement auth, set up a database, or build out additional functionality.
