v0 gave you exactly the interface you pictured, in minutes. If you're now discovering that the buttons don't save anything, the data is hard-coded, and there's no login or database behind it, that's not a bug. It's the gap between an interface and an application, and it's exactly the gap we close.
We take v0 prototypes to production: auth, payments, integrations, data, security and hosting. Then we hand it over, or we keep running it. Part of our prototype to production service.
A free 20-minute look at what breaks at launch and what it costs to ship.
THE DIAGNOSIS
The Failure Modes We See Most
If your v0 project is stuck, it is almost certainly one of these. Read the one that sounds like yours. The fix is usually smaller than it feels.
It's an interface, not yet an application
v0's job is generating interface components: screens, forms, tables, dashboards. It does that job well. What it doesn't generate is the application behind them: the server, the database, the logic that makes a button actually do something.
This surprises people because the result looks like an app. Click around, though, and nothing persists: the form clears, the table shows the same rows, the settings don't save. Everything visible exists; everything invisible is still to build.
What actually fixes it: Design the data model and backend the interface implies, then wire every screen to it. The interface you have becomes the specification for the application you need.
The mock-data trap
Generated components arrive filled with placeholder data (example customers, sample orders, plausible numbers) written directly into the code so the design looks real.
Replacing it is more than swapping in a data source. Every component needs loading states, error states, empty states, and real pagination: the things mock data let you skip. This is usually the single biggest block of work between a v0 design and a working product.
What actually fixes it: Replace hard-coded data with real data fetching, screen by screen, adding the loading, error, and empty states that production data demands.
No auth, no database, no deployment
A real application needs accounts and login, a database with backups, a server for the logic that can't run in the browser, and hosting with a domain. v0 doesn't claim to provide these, but their absence is what keeps the project a design.
Each piece involves real choices (which auth approach, which database, where to host) that depend on what the app is for, who uses it, and what it must never lose.
What actually fixes it: Stand up the production foundation (auth, database, server, hosting) sized to what the app actually needs, not to a stack someone else's tutorial used.
Components that drift apart
Screens generated across different sessions each look fine alone but disagree in the details: buttons that differ subtly, two date formats, props that don't line up when screens need to share data.
Each generation is independent. There is no shared design system holding the pieces consistent, so assembling many generated screens into one coherent app takes deliberate reconciliation.
What actually fixes it: Consolidate the generated screens onto one shared set of components and conventions, so the app behaves and evolves as one product rather than a collection of pages.
The last 20% still applies
Once the backend exists, the same finishing work every app needs is still ahead: validation, security, email delivery, monitoring, mobile behavior, and the edge cases that only real users find.
The good news: starting from a precise interface makes this stretch faster than usual. The hardest product questions (what should this look like? how should it work?) are already answered on screen.
What actually fixes it: A standard hardening and launch pass over the finished app, with your v0 design serving as the acceptance criteria.
To be clear: v0 is genuinely good at what it does. It produces high-quality interface code faster than any alternative. The patterns below are not v0 failing. They are the difference between generating an interface and building an application. We build the application behind what v0 designed.
WHAT WE DO
Your v0 app, production-grade
It works in the demo. Real users find the rest. We finish the parts a demo never needed.
Auth
Login, roles and password reset that hold up on the server, not only in the browser.
Payments
Checkout, webhooks and failed-payment handling, so money and records agree.
Integrations
Email, your store, your CRM and other APIs, with retries and alerts when a call fails.
Data
A real database with backups, a clean data model and a safe way to change it.
Security
Access rules on every table and endpoint, secrets kept off the frontend, and a pass that tries to break in.
Hosting
A production environment, your own domain, monitoring, and deploys you can repeat.
Built on Firebase? Good.
Many AI-built apps run on Firebase. We run Firebase apps in production for clients, so we know where prototypes on it tend to break.
Security rules left open. Auth flows that skip the edge cases. Cloud Functions with no retries or logging. Queries that get slow and costly once real data arrives.
We fix those in place when Firebase is the right home for your app, and tell you plainly when it isn't.
Then we hand it over, or we keep running it
We hand it over
You get the code in your repository, the hosting set up in your accounts, and notes on how it fits together. Your team or your next hire takes it from there.
We keep running it
We watch it, fix what breaks and ship improvements each month on a Co-Build plan. You can still take it in-house later.
We run our own fleet of AI coding agents. Models from different families review each change, tests run against it, and an engineer who is accountable for the work decides what ships.
The $500 Production Readiness Audit, credited 100% toward the build
Send us your project and we tell you what is actually broken, where the security gaps are, and what production-ready costs, in fixed price bands, with a 72h turnaround. The fee is refundable until the kickoff call. If you go ahead with us, every dollar is credited toward the build.
